Deep Earth subject of Tues., June 15 Virtual Program Meeting

Join us Tuesday, June 15 for a journey through the deep Earth, with Dr. Krista Sawchuk. The deep Earth, which encompasses the mantle and core, makes up 99% of our planet. Because we can’t physically go to the deep Earth, scientists employ a variety of techniques to learn more about it. Dr. Sawchuk will share what we do know about the deep Earth and how her research on the behavior of minerals at high pressures and temperatures is helping us learn more about the chemistry of the mantle.

Dr. Sawchuk recently graduated from UCLA with a PhD in geochemistry. Her dissertation research focused on the high-pressure behavior and chemical reactions of volatile-bearing minerals in Earth’s mantle. Since graduating, she started a postdoctoral research
position at Los Alamos National Lab in New Mexico where she continues her high-pressure research. In her spare time she enjoys mineral collecting and curating her personal mineral collection.

The Tuesday, June 15 program meeting starts at 6:30 p.m. via Zoom. To join us, send an email to joenmar1[at]verizon.net in advance, using ‘PROGRAM MEETING’ in subject line, and request the Zoom meeting link. We hope to “see” you there!

Obsidian Featured Presentation for Tuesday, April 20, 2021 Program Meeting; 6:30 p.m.

Obsidian is a popular lapidary material to collect and cut. Join Pasadena Lapidary Society at the April general meeting, as lapidary artist Terry Wilson takes us on a virtual trip to Davis Creek and other obsidian collecting locations, updating us on collecting site regulations. Terry will share tips on how to inspect the obsidian in the field and back at home. She will also demonstrate how to line up, slab and cab the material to bring out the best of their unique optical properties, including how to cut a cab exhibiting the cat-eye effect.

Explore the Geologic Diversity of New Zealand; Virtual Program Meeting March 16, 2021, 6:30 pm

Pasadena Lapidary Society’s Tuesday, March 16 program meeting will feature geologists Dick and Mary Pat Weber, whose presentation will focus on the geological wonder of New Zealand. From volcanoes to glaciers, caves and fjords, finding so much variety of terrain in such a small geographical area would be impossible anywhere else on Earth.

The Webers are exploration geologists who spent a month in 2007 visiting every corner of this tiny island nation; they have worked and travelled extensively in North America, Australia and New Zealand.

Our program meeting will also feature the Rock of the Month, by PLS member David Lacey, whose presentations are always informative.

Focus on Ametrine for Tuesday, February 16th

Join us for our next virtual general meeting on Tuesday, February 16th. We will be joined by our friend, Professor George R. Rossman. Professor Rossman will highlight the troubled history of Ametrine. Specifically, he will discuss the controversy that developed about ametrine early on, and his personal experience traveling to Brazil amethyst mines, the Bolivia ametrine mine, and Russia where synthetic ametrine was produced. RSVP to joenmar1[at]verizon.net for a Zoom meeting link, using ‘AMETRINE’ in subject line.

The Rock of the Month will be presented by PLS member Phil Lahr, who will discuss “Tumbling through the Pandemic” – a personal journey of rock tumbling triumphs and tragedies during the summer of 2020.

Rhodochrosite Focus of February 18th Meeting

Rhodochrosite is so popular with members of Pasadena Lapidary Society that we’re bringing back a two-part video featuring the mining and geology of this lovely mineral. Part One will be presented at the Tuesday, February 18th program meeting. Rhodochrosite is a manganese carbonate mineral that ranges in color from light pink to bright red.

The February Rock of the Month Talk speaker is PLS member Karl Stull. Karl will share some tips and ideas for organizing a co-op display case for Pasadena Lapidary Society’s Annual Gem Show, coming in April.
