PRESIDENT'S CORNER:

December 2018,

Hello SDAG readers,

The air has brought a chill to its breath, the leaves have changed their color and laid to rest, and the day fades to night more earlier than ever. The time has come to end an aging year and begin fresh for a new year! I have been privileged to walk you through 2018, from our monthly meetings to One Stop Wonders. I hope you have enjoyed the journey. I will be standing down next year to allow the next ambitious president to grab the proverbial hammer and forge through the future with passion and determination.

I want to thank Ken Haase, Adam Avakian, Heather Reynolds, and Carolyn Glockhoff for their help during 2018. They have been instrumental at the meetings and behind the scenes, as well as Dave Bloom, Monte & Diane Murbach, Greg Cranham, Bob Stroh, and Lowell Lindsay, as SDAG's relationship continues to hold strong with SDGS.

Farewell for now and I look forward to seeing all of you at future events!

Sincerely,

Chris Livesey -
SDAG President


John A Minch

Dr. John A. Minch

With sadness we convey the passing of Dr. John A. Minch on Wednesday, November 21st, 2018 following a long and valiant fight with prostate cancer. John's spirit and enthusiasm for geology and paleontology will most assuredly live on in his many thousands of former students, both in the U.S., and in his beloved Baja California, his colleagues, prolific publication of hundreds of papers, books, and volumes; and particularly by his proud editing and publishing of the entire Dibblee Geologic Map Series of California. John was unique in his innate ability to have excelled both in academia and teaching which spanned more than six decades, and in business where his eldest son now proudly carries on with the success of John Minch & Associates. His deep commitment to the geologic community was felt from national AAPG committees and conventions to local society chapters and private foundations in California. John's passion for geology was evident in his broad expertise across so many specialties of the profession, ranging from paleontology, geology, and engineering geology, to mineralogy and mining, to coastal and marine geology, faulting and tectonics of the California Continental Borderland. His latest geologic guidebook completed a near lifetime study of the geology and active faulting along California's international border with Baja California, an area he began studying as an undergraduate and later, a graduate student of Edwin Alisson and Gordon Gastil with whom he shared his passion for Baja and its unique geology. Most recently, John's publication of the San Diego Association of Geologist's guidebook to the Geology and Geologic Hazards of Northwestern Baja California: The Gold Coast & Agua Blanca Fault contained much of his and other's groundbreaking work in northwestern Baja, and significantly focused on the cross-border active faulting and tectonics which is so important to the safety of millions of residents on both sides. John is survived by his wife Carol, three children Edwin, Jennifer, and Jason, and 7 grandchildren. Private funeral services will be held on December 5th, 2018. A celebration of life event is planned for early 2019. If you would like more information on this event, please e-mail generationgraphics@cox.net . In lieu of flowers or gifts, please donate to your favorite charity or local geological society to help the next generation of passionate geoscientists.

Calle Guadalajara Landslide - One Stop Wonder

Calle Guadalajara Landslide - One Stop Wonder

Stephen Jacobs is leading our first OSW of 2019 to observe a large landslide in San Clemente. The OSW is scheduled for Saturday, January 5, 2019 from 10am to 12 noon.

Access to the landslide complex is via a trail leading from Calle Guadalajara. Parking near the trailhead is along the street on Calle Guadalajara between Calle Corral and Calle Reata in San Clemente. The proposed meeting time will be 10:00 am to 12:00 pm on Saturday, January 5, 2019.

An interesting landslide complex in an open area of San Clemente has progressed in size since about the mid 1990s. It represents a series of reactivated slides within an ancient landslide complex underlain by the Capistrano Formation according to the Geologic Map of the Dana Point Quadrangle mapped by Tan (1999). The latest and most prominent reactivated portion of the slide complex, which apparently formed in about 2011, is near the eastern part of the mapped area of the ancient landslide complex. This area has an approximately 15- to 20-foot high head scarp with ancient landslide material exposed in the scarp face.

2018 SDAG Field Trip October 12th to 14th 2018

From our Vice President Ken Haase:
Hello SDAG!
I would like to extend my heartfelt thanks to everyone involved with the 2018 Field Trip. We had about 50 people come along and explore the geology of the Mojave Desert. This trip was almost 11 months in the making and it went off without a hitch (maybe a little rain). Thank you to my trip co-leaders Dr. Mario Caputo and Dr. Monte Marshall who's endless geologic knowledge surely made this trip infinitely more interesting than I could have on my own. Dr. Norrie Robbins who unfortunately couldn't make the trip (feel better soon!) but provided great insight into the human history of the Mojave. Thanks to Brian Papurello and crew for setting up the camp kitchen and keeping our bellies full. A big thanks to the SDAG officers, Chris Livesey, Adam Avakian and Heather Reynolds who have been such great help before and during the trip. As always, Diane and Monte Murbach provided the Hawaiian theme and margarita drinks each evening so thanks to them and SDGS board members. Geocon, my employer was gracious enough to provide the beer kegs which kept people more than happy. And thanks to everyone who came on the trip to make it so special! We are working on preparing the volume for the trip, hopefully to be published in 2019. It has been a humbling experience and I thank everyone for their kind words on their enjoyment of the trip. Can't wait to see what our 2019 VP Adam Avakian has in store for us next year.

Keep exploring and see you out there!

Geology Education Rule Making Notice - Board of Professional Engineers, Land Surveyors and Geologists

On November 30, 2018 the Board for Professional Engineers, Land Surveyors, and Geologists (Board) published the Geology Education Rulemaking Notice. The Board proposes to adopt Title 16, California Code of Regulations sections 3022, 3022.1, 3022.2, and amend Title 16, California Code of Regulations section 3031.

2019 SDAG Annual Field Trip - Owens Valley, CA

Hi SDAG members. My name is Adam Avakian. I am the current secretary and future 2019 vice president for SDAG. I am very excited to be tasked with pulling together the annual field trip for 2019 and have some big shoes to fill after attending our latest trip out to the Mojave Desert (thanks to Ken and everyone involved for an amazing trip, and what an awesome group photo!). I am planning on taking us to Owens Valley / Eastern Sierras. I have a few stops in mind already but could definitely use some help on more stop suggestions and especially any enthusiastic speakers who have some knowledge and a love for the geology of Owens Valley. Here is a sneak peek at next year's trip:
  • Owens Valley Fault - 1872 Earthquake Fault Scarp - Lone Pine.
  • Alabama Hills - I was recommended a very interesting geological feature to look at here, also potential campground
  • Poverty Hills Geology - Owens Valley Fault Pressure Ridge and beautiful fault scarps preserved in basalt flows - Tinemaha Dam - Big Pine
  • Crowley Columns - Lake Crowley
  • Bishop Tuff - Ideas??
  • More ideas (basalt flows, glacial moraines etc.??)
Because it's a long drive and there is a lot to see I would like to try to start the trip Friday morning which would require participants to either get up extremely early Friday morning to drive or to camp out with the group Thursday night (my preferred option) or you can join the group midday on Friday. The bulk of the trip would be completed Friday and Saturday. I think I will plan for a half day of stops on Sunday and try to make them on the way back south towards home. Sunday would also be optional if anyone wants to get home earlier they can head out Sunday morning and skip the stops. Any help or advice would be much appreciated. Like I said, speakers are more than welcome. I'm planning to speak at Tinemaha Dam as my company has done work there but that's all I've got so far! Please send responses to adam.avakian@aecom.com.

Cheers! Adam


OSW - Encinitas Copper Mine - Write Up by Jennifer Morton

Encinitas Copper Mine (a.k.a. Danes Lea Mine) N33.081651 W117.208037
Rancho Santa Fe Quadrangle
Directions:
Take I-5 to La Costa Avenue, head east. Turn left onto Rancho Santa Fe Road and right onto San Elijo Hills Road. Bear right at the roadway to a closed landfill and park on the side of the road. Head south on the easternmost dirt path, next to the landfill building. Arrive at the head of Copper Creek trail. Follow this trail until you reach the waterfall and remnants of the mine workings.

OSW Encinitas Copper MineOn September 1, 2018, SDAG visited the site of the Encinitas Copper Mine in the La Costa Preserve. The old mine was situated along what is now known as Copper Creek. According to County Report 3, Geology and Mineral Resources of San Diego County, California, published by the California Division of Mines and Geology in 1963, the mine was discovered in 1887 and was worked until 1917.

We were joined by Richard Bumann, local author/historian and a descendent of one of the founding families of Olivenhain. Mr. Bumann's uncle owned the copper mine from the 1920's through 1940's, and he shared some of the history of the mine and boyhood stories of exploring the mines and at one time lowering himself into one of the shafts! Mr. Bumann confirmed that the mine consisted of two shafts, one on either side of the canyon through which Copper Creek flows. The mine was worked sporadically until 1917, producing a low-grade extract than it would be worth! Piles of light-green rocks - the remaining mine tailings - give away the locations of each of the shafts, which have since been blasted shut for safety. The shaft on the east side of the canyon consisted of two horizontal tunnels terminating at a 140-foot deep vertical shaft, and the shaft on the west side was reported to be a vertical 400-foot shaft. The shafts tend to flood with groundwater, and Mr. Bumann's uncle spent many months pumping out water and restoring the shoring in 1925, but the mine was never again worked.

OSW Encinitas Copper Mine According to the 1963 County Report, the deposit is a northwest-trending zone copper-bearing mineralization, approximately one mile long and 10 to 50 feet wide. The 1939 California Journal of Mines and Geology, Quarterly Chapter of State Mineralogist's Report XXXV describes the vein as a yellowish and black gouge between walls of dark-colored porphyry, and notes that the ore is chalcopyrite associated with pyrite.

OSW Encinitas Copper Mine Steven Jacobs provided a great overview of the formation of porphyry copper deposits. These types of deposits typically form as the result of hydrothermal activity. In the case of the Encinitas Copper Mine, as the magma body of the Western Peninsular Ranges Batholith intruded the Santiago Peak volcanics hydrothermal fluids circulated through preexisting rocks, altering these rocks and depositing metals in the matrix or as a coating in fractures on the surface of surrounding rocks.

Monte Marshall was on hand to discuss the formation of the Santiago Peak Volcanics. These are subduction-related volcanoes, similar to the Andes or the Cascades. He noted that a visible outcrop near the mine consisted of a volcaniclastic deposit - one of three types of structures typically seen associated with the Santiago Peak Volcanics. Others include flows and feeder dikes with vertical foliation.

Thank you to everyone who made this a successful OSW!

NEW Interactive Fault Map for San Diego

As part of the update for the San DiegoTijuana Earthquake Planning Scenario, Working Group No. 1's "Fault Map Subcommittee" completed the first publicly available bi-national active and potentially active fault map (http://sandiego.eeri.org/?page_id=265). This interactive GIS map includes the first publicly available active and potentially fault map locations from the City of San Diego. The map also integrated the faults south of the border for a bi-national cross border view. This map is an on-going project as our knowledge increases about local active and potentially active faults.

You can expand the map legend on the left side to select layers that can be turned on or off for the map view. You can also select from 1 of 12 base maps at the base map icon. You can click on the fault line in your map layer view to see the meta-data source. In addition, the City of San Diego Seismic Safety Study Geologic Hazards & Faults Maps are available in the layer titled "GeoHaz SD City." Please note that the City "Zone 12 Potentially Active" fault layers was not included in this data, therefore you will need to use the City Maps to find Zone 12.

The Fault Map link is available at: http://www.sandiegogeologists.org/Faults_map.html

I would like to thank Carolyn Glockhoff for her endless GIS work, Jim Quinn and the City for providing their data and time, Jerry Treiman with CGS for his time preparing the Surface Rupture and providing their new State fault data layer, and Luis Mendoza at CICESE for providing the faults south of the border. Please contact Diane Murbach (dianemurbach@gmail.com 619-865-4333), Chair for the SDTJ Earthquake Scenario Working Group #1 - Earth Science, if you have any questions, or see any errors on this new fault map.

Photo of the month CALL FOR PHOTOS!
That's right!...It's back, the SDAG monthly photo competition, featuring the very best of member photo submissions from around the County and beyond. The prize is one free drink at the next meeting, so if you're a winner, just see our resident bartender extraordinaire, Cari Gomes at the next meeting.....or myself (The Secretary) if it's not a SDAG libation supplied event.

This picture was taken by my dad, who isn't a geologist but a land surveyor. He's quite the naturalist, but it doesn't take a geologist or naturalist to recognize the beauty of this rock! I mean, wow!! He took this picture while working on the job. The location will remain a secret as property owner probably doesn't want a bunch of crazed rock hounds trying to raid his rock garden in the middle of the night. I'm assuming these are mafic inclusions in some kind of coarse grained plutonic rock and at the bottom of the pic you can see a coarse grained felsic vein cutting through the mafic inclusions. How cool right?!?! Not sure about you guys but I never knew how beautiful mafic inclusions were in cross section, unless these are some sort of special mafic inclusions. Enjoy!

CALL FOR ARTICLES! SDAG invites members to submit articles on their current research or an interesting project they are working on for publication in the monthly newsletter. The article should be no more than 1 page in length. Photos are welcomed, too! Please submit articles to the SDAG secretary via email.

The "Lindavista" Fm: Marine Terraces to Terrestrial Terraces and all Plants in Between

by Eleanora (Norrie) Robbins, PhD (USGS-retired; SDSU-retired)

I have several specialties, one of which is iron bacteria. So anytime I see red rocks I wonder if iron bacteria had a role in their formation. Recently I've been fixated on the red sandstones at the top of the cliffs at Cabrillo, Torrey Pines, Crest Canyon, and along Highway 52. Tom Rockwell teaches that these red rocks were all Pleistocene marine terraces that have been uplifted to become terrestrial terraces in the past 1.5 or so million years. He and his predecessors have mapped seven old terraces and thirteen very old terraces. In general, the red sandstones on these terraces are called "Lindavista" Fm.

If you drive to Torrey Pines, you've seen the large vertical structures that start in the Lindavista and continue down into the Torrey Sandstone. I am fascinated with Pat Abbot's hypothesis that these large structures might have been mineralized tree roots. That got me thinking about the plant communities that would have colonized the marine sediments when they were uplifted into the terrestrial environment. The first plant community growing on uplifted marine sands had to have been coastal salt marsh; then I presume fresh water marsh, forested wetland, grassland, and now the rocks are colonized by coastal sage scrub and Torrey pines. Using this as my model, I am trying to unravel the post-depositional history of these rocks.

Lithified but never buried, the "Lindavista" is cemented with iron oxide. What was the source of reduced iron that could be oxidized? My working hypothesis is that the sediments contained iron monosulfides and pyrite that formed during the marine and coastal salt marsh phases. I am thinking that with uplift, the iron sulfides were oxidized by iron bacteria to ferrihydrite. If the sediments then went through a salinity phase (i.e., sea level rise), ferrihydrite would dehydrate to hematite; but using reflected light, I rarely see hematite in any of the rocks.

Another fascinating characteristic of the "Lindavista" are Mn-rich soil concretions and nodules. In Virginia, I worked in a wetland that was actively forming these; there, iron bacteria were active in the subsurface where the concretions formed. In places, the "Lindavista" concretions form vast accumulations at the surface, where we call them rollers because they are easy to slip on (ask Joe Corones). I presume that they are residual lag deposits from sediments and rocks that have eroded away.

Thinking as a paleoecologist, I've started tromping around our coastal salt marshes: Tijuana, Sweetwater, South Bay, Los Penasquitos, and all the coastal lagoons. In these, I'm searching for sedimentary structures, distinctive shells, and sediments with iron sulfides.

There's more to the story, such as the abundance of magnetite in the rocks. The magnetite is perfectly black under the microscope, not rimmed red. I don't understand its provenance and its role. And where are the shell fossils from the marine history? The only shells that have been collected are from the base of the Lindavista, only inland, where it sits on calcareous rocks.

I've been taking the students I mentor out in the field with me, seeing if I can interest some of them in these rocks. But they need a funded professor to move forward with XRD and thin sections; I'm retired. I do welcome anyone who wants to tromp with me on the red sandstones or in the stinky marshes.

Looking For A Sample of Ardath Shale

I am curating an exhibit for the La Jolla Historical Society about Canyons. We would like to include a specific exhibit - a chunk of Ardath Shale. It ties in to so many of our other items: how La Jolla was formed, ecology and native plants, as well as the issue of landslides. For example, the Soledad Mountain Road slope failure of a few years ago was related to the geology: heavy soils over Ardath Shale...according to the reports I've been reading. I'd like to show our visitors what exactly Ardath Shale looks like.

Does your organization have a sample of this type of rock? If not, can you suggest where I might find a sample large enough to put on display?

Got too many rocks? Are you (or specifically, your spouse...) interested in giving them a good home *away* from your house and garden? Mesa College is looking to collect some rock samples for an inaugural Earth History course. We are specifically looking for sedimentary rocks that include examples of different energy environments (varying grain sizes and shapes) and structures (ripples, cross bedding, planar bedding, graded bedding, etc.). We are also looking to beef up our fossil collection and are looking for all the major phyla: Echinoderms, brachiopods, mollusks (bivalves, cephalopods, gastropods), arthropods (trilobites and more!), corals (Cnidaria), Porifera, Bryozoa, vertebrates (Chordata), etc. Looking for both actual standalone specimens or in the rock still (showing different environments of deposition). We are looking for fossil preservation examples, and also for good trace fossil evidence. Got any sediment grain samples from cool locales? We'll take them! If you have anything else you think provides a good 'story' in the rock, we are willing to check it out! We are collecting ASAP to assess how much needs to be ordered for the fall course. Please contact Jill Krezoski at JillKski@hotmail.com or Don Barrie at dbarrie@sdccd.edu with queries or samples.

ROCK DONATIONS NEEDED: Amy Romano, one of our former student members, is looking for rock donations. Amy is currently attending Humboldt State University and majoring in Geology. She is very involved with Humboldt's Geology Club, and every year the club holds a rock auction to support their activities. If you have any rocks to donate, please contact Amy at ajr612@humboldt.edu.

Annual Scholarship Awards by the San Diego Association of Geologists, a program of the San Diego Geological Society, Inc.

A primary function of the San Diego Association of Geologists (SDAG) is to support academic opportunities in geology and related sciences. By-laws of the San Diego Geological Society (SDGS) specify the support of academic opportunity ranging from elementary through graduate levels. The SDAG scholarship program has supported academic research in higher education by awarding scholarships annually to students from two-year and four-year undergraduate and master's level programs. Awards are for outstanding research in geology and related sciences. Nominations are solicited from individual faculty and from geology or related science departments at accredited academic institutions. Evaluation of the relative merit of each nominee is based on an abstract describing the objectives and results of the research being conducted by the student and on the letter of recommendation by the student's mentor or nominating committee.

The annual timeline is as follows:
  • Request for nominations occurs in September.
  • Nomination letters and research abstracts are received by the Scholarship Coordinator in mid to late October.
  • Awardees and their nominators are invited to attend the December SDAG dinner meeting. Scholarship awards are distributed to the student during the December meeting.
  • Students accepting awards are required to give a presentation of their research results usually at a spring dinner meeting of SDAG.
For further information contact SDGS Board at http://www.sandiegogeologicalsociety.org/contact.html through the Contact Us option

SDAG RESEARCH TOOL

A comprehensive listing of all papers published by SDAG, whether as annual field trip guidebooks or special publications, is available on our website. Entries are sorted by primary author, or chronologically by date of publication, from our first guidebook in 1972, up the San Luis Rey River in 2013, from Coast to Cactus in 2014, and finally over the edge to the Coyote Mountains in 2015. These can be accessed or downloaded as .pdf files. They are fully searchable in Adobe Reader or Acrobat, so if you are researching a topic, "tsunami" for example, you can search for that keyword. This listing will be updated as new books are published. Thanks to Greg Peterson and Hargis + Associates, Inc., for making this possible. See the links below:
