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!














March’s field trip will be a return to the Sidewinder Mountains. High clearance or short wheelbase vehicles are recommended for this trip. 2wd is okay. Those with passenger vehicles might need to be shuttled when we get close to the collecting sites. We’ll be searching for both tri-color marble (pictured above) and blue marble. Tri-color marble is a beautiful green, black, and white material and is perfect for yard rock and spheres. It’s also a good beginner material for making cabochons. We’ll also explore tailings piles in the Ord Mountains for chrysocolla and malachite.
