Georgia Mineral Society

The final day of Tellus Science Museum 's Mineral Symposium starts in an hour!! Click on the event for the live stream on Field Collecting from Jeff Deere!

Tune in tomorrow at 12:15PM! "Thirty-five years as Exhibits Chair for the Tucson Gem and Mineral Show (TGMS) has given Peter Megaw unique access to the international mineral community and many of the community’s most august personalities and institutions not to mention the inner workings of mineral shows worldwide."

Happy St. Patrick's Day from the Kentucky Geological Survey! What a cool technique!

Tellus Science Museum shared day 1 of their 2021 Mineral Symposium on mineral collecting with Christopher Clark discussing "The Crystal Habit - Collecting Minerals, Gemstones, And Jewelry"! Be sure to tune in tomorrow at 12:15PM for day 2 with Jose Santamaria on "Caring For Your Collection"! Visit https://tellusmuseum.org/museum-events/events/ to see the upcoming topics. Check out https://gamineral.org/ for Georgia Mineral Society's monthly meetings to learn more about awesome topics like those being covered in this symposium!

"The way crystals grow in nature is always fascinating. This tourmaline, which originally grew as a single black crystal, dissolved and regrew as thin, 'hairy' ...fibers. Each fiber is actually an individual tourmaline crystal. Amazing!" - Michael Wise, Mineral Sciences @smithsoniannmnh #NatureNerding101 See more

Walking between the rolling clay hills at Petrified Forest National Park in Arizona, you can stumble onto a scene that looks like a lumberjack went mad. But thi...s wasn't the work of an axe or saw. Over 200 million years ago, fallen trees washed into an ancient river system and were buried quickly enough that oxygen was cut off and decay slowed. Minerals, absorbed into the porous wood over thousands of years, crystallized and replaced the organic material forming what we call petrified wood. The crystals are hard and brittle, fracturing easily when subjected to stress. Over time, the still buried petrified trees broke like glass rods -- giving the appearance today of logs cut with a chainsaw. Photo by Jacob Holgerson, National Park Service. See more

Bryozoans, known as moss animals are common fossils in rocks that were laid down in marine environments. Typically found as small branching or fanlike pieces,... (around 2.5 inches), the colony you see here had to be assembled from smaller pieces found in these rocks. Three scientists, (shout out to Mark Erickson, David Waugh, and Robert Crawford!) with boundless patience, assembled some 200 bryozoan pieces found in one area to reconstruct this bryozoan colony (known as a zooarium). The assembly and gluing took about 100 hours! The individual branching elements of this complex colony are arranged so that sea water could flow through the colony, allowing tiny zooids (each less than 1 millimeter wide) that line the exterior of the branches to feed.

A variety of colorful rocks in mountain lakes can be evidence of past glacier activity (but not always). At Grand Teton National Park in Wyoming, 11 active glac...iers continue to grind through different layers of rocks, mixing together stones with different mineral make-ups. These lovely rocks, clear waters and breathtaking mountain views are just some of the things that make Grand Teton a popular park. Photographer Josh Packer was recently excited to get back to the park, "I drove 6 hours round trip and had to leave at 2:30 in the morning to get here by sunrise, and what a sunrise it was! Hard to beat a calm, peaceful morning like this." Photo courtesy of Josh Packer Photography. See more
