Green Minerals & Rocks

LINK TO THE FREE ROCK IMAGE ID KEY: https://rockpapa.github.io/Rock-Image... In this video, we explore the fascinating world of green minerals and the green rocks they form — and, most importantly, where those green colors come from. Filmed in the beautiful Great Smoky Mountains, this episode looks at how chemistry, geology, and tectonic processes combine to create some of nature’s most eye-catching minerals and gemstones. We cover a wide range of green minerals and rocks, including: • Beryl and its green gemstone varieties, including emerald • How trace elements like chromium and vanadium produce rich green colors • Why many green gemstones form in pegmatites — granite bodies with large crystals • The special case of Colombian emeralds, which form in altered limestones rather than pegmatites • Hiddenite, a green variety of spodumene colored by trace chromium • Amazonite, a green potassium feldspar colored by trace lead • Malachite, a secondary copper mineral commonly associated with limestone • Unakite, a rock made of pink feldspar, green epidote, and quartz • Olivine, a magnesium- and iron-rich mineral from Earth’s upper mantle • Peridotite and its alteration to serpentinite, one of the most widespread green rocks on Earth Along the way, we discuss how aluminosilicates, volatile elements, hydrothermal fluids, and tectonic collisions all play a role in producing green minerals and rocks. This video is designed for rockhounds, students, hikers, and anyone curious about how Earth makes color.
