SDAG Events / Announcements

PRESIDENT'S CORNER:

Greetings SDAG members,

Thank you to all those who contributed to, and attended last month's annual field trip to the Ramona/Julian area. As always, an enjoyable time was had by all! Chris expertly managed taking the P. G. exam, leading the fieldtrip, and expanding his family with twins, all in the same month!

The completion of the field trip brings us to the final two meetings of the year. This month brings an update on the geology of Mission Trails Park from Dr. Pat Abbott. Our Christmas meeting will feature our annual paleontological update from Dr. Tom Deméré at our favorite venue, the San Diego Natural History Museum. Details for both meetings are included herein, so sign up as soon as possible!

As always, please feel free to contact me at adams@geoconinc.com if you have questions, suggestions etc. regarding all matters SDAG related.

I look forward to seeing everyone again on the 14th at Phils BBQ!

Regards,

- Rupert Adams | Sr. Project Geologist / SDAG President

2017 SDAG field trip, Julian-Banner Mining District - A Road to Gold

From Chris Livesey:

turkeys on 2017 field trip For those who could not attend the field trip, the event was enjoyable and the weather, although hot and windy on Saturday, was bearable. We hiked vigorously and enjoyed talks regarding geology, mineralogy, ecology, and history. Geologic jokes were exchanged throughout the trip!

I had a lot of fun orchestrating the field trip and, at the least, I hope everyone enjoyed the trip. I wanted to express my gratitude to all who attended the field trip and worked alongside me. A lot of planning and help was incorporated into our annual field trip(s) and guidebook(s). In no particular order, I would like to express my gratitude to all that helped: Jen Livesey (who allowed me to spend copious time and effort into the trip, despite the fact she was incubating our twin boys, with a due date of October 11-18 and delivered at a convenient week later, so I could fulfill my duties) Pat Abbott, Bill Elliot, Mike Thacker, Monte Marshall, Monte and Diane Murbach, Martin Learn, Lowell Lindsay, Bob Stroh, Adam Avakian, Ken Haase, Jen Morton, the operation staff at Hollow Creek Ranch, Toni and Mike Menghini, Carole and Mike Ziegler for sponsoring the Menghini wine during Saturday night, The San Diego Historical Society, Gemological Institute of America, JR Morgan, Dave Kimbrough, Marty Grove, and Mike Jensen.

I wanted to leave you with a memory, that I enjoyed for some peculiar reason. During the second stop, near Hollow Creek Ranch (who allowed our attendees to park on their property) our vehicles surreptitiously, by no premeditated intent, corralled a Rafter (group of wild turkeys) for a brief moment. As the jokes continued to roll through the stops, some one yelled out:

What is a turkey's favorite rock?

SDAG field trip 2017 participants Thank you to all of the 2017 Field Trip Participants. SDAG enjoyed a wonderful trip to Julian led by our Vice President Chris Livesey whose wife just had twins! Congratulations Chris and thank you for a great trip!

Sad, but true... now may be a good time to look at the geology of Puerto Rico without all the obscuring vegetation which Hurricane Maria removed.

Diamond-Lesedi La Rona sold for $53m to London Jeweller

Lesedi La Rona diamond - Image copyright Graff Diamonds
The world's second-largest gem-quality diamond has been sold to a London jeweller for $53m (39.5m).
Laurence Graff, chairman of Graff Diamonds, bought the diamond privately after it failed to meet its reserve price at an auction last year.

The 1,111-carat stone was recovered by Canadian firm Lucara Diamond Corp in Botswana two years ago.

Lucara said the price was an improvement on the highest bid received at Sotheby's in June 2016.

The diamond is named "Lesedi La Rona", which means "our light" in Botswana's Tswana language.

The stone was first formed between 2.5 to three billion years ago and is roughly the size of a tennis ball. A team of cutters will work out the best way to maximize the stone's potential. As well as its size, the diamond has been certified as being of "exceptional quality and transparency" by the Gemological Institute of America.

NEW Interactive Fault Map for San Diego

As part of the update for the San Diego-Tijuana Earthquake Planning Scenario, Working Group No. 1's "Fault Map Subcommittee" has completed the first publicly available bi-national active and potentially active fault map. This interactive GIS map includes the first publicly available active and potentially active fault map locations from the City of San Diego. The City of San Diego fault locations and activity of faults are based chiefly on interpretation of information contained in geologic reports by private consultants. The City of San Diego identifies active faults as Holocene (<= 11,000yr) and potentially active as Quaternary (up to 1.6my). City of San Diego fault investigations are ongoing that may require future revision of this map. This map is not a substitute for a site specific fault investigation. The map also includes an updated fault map layer from the State CGS. CGS suggests users defer to the City of San Diego fault data, where marked, for increased accuracy. The map also integrated the faults south of the border for a bi-national cross border view. You can expand the map legend on the left side to see the fault ages and sources for each layer that can be turned on or off for the map view. You can select from 1 of 12 base maps. You can click on the fault line on the map to see the meta-data source. This map includes the yellow dashed SURFACE FAULT RUPTURE location layer that will be used for the infrastructure, social, and economic impacts and emergency response for the update to the Earthquake Scenario. In addition, active and potentially active fault investigation locations from private companies are planned to be added to this map as a resource. This map is an on-going project and resource as our knowledge increases about local active and potentially active faults.

The 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), Chair for the SD-TJ Earthquake Scenario Working Group #1 - Earth Science, if you have any questions, or see any errors on this new fault map.

STATE REGISTRATION EXAM HELP One of our new members, Sergio Postigo who has recently moved to the San Diego area, will be taking his registration exams later this year for the PG. Sergio is looking to meet up with anyone who may be interested in forming a study group for the exam and/or hear from anyone who has recently taken the exam and can provide some useful insights. He can be contacted at Email sergiopostigo@yahoo.com


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 (40 years ago!) to Palms to Pines and San Luis Rey volumes recently printed. 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:

SDGS/SDAG

As many of you are aware, the San Diego Geological Society (SDGS) was formed in early 2010 as an official non-profit 501(c)3 corporation, and SDAG is now an organization under this corporation. The reasons for doing this were many and they are spelled out in an informational sheet, the Business Plan of SDGS. The officers of SDGS should be very familiar to you, as they are all past presidents of SDAG. For those of you that would like to read more about SDGS and what it means to SDAG, check out the informational page on the website. Also check out the website www.sandiegogeologicalsociety.org.
