​Product Description

​Discover the rugged mineralogy of Western Colorado with this captivating multi-mineral matrix specimen, self-collected from the precarious cliffside workings of the Goat Trail Mine in Garfield County. This piece serves as a textbook example of complex geological formation, showcasing a striking contrast of colors, textures, and crystal habits all anchored to a single host rock.​The specimen features a dominant, milky-to-translucent quartz matrix embedded with rich, contrasting pockets of deep black, sub-metallic minerals—likely a mix of iron-rich biotite mica and dark tourmaline or amphibole. Strikingly perched on the sides are distinct, silvery-tan book-like clusters of muscovite/phlogopite mica, showing off their classic micaceous, layered splitting planes that brilliantly catch the light. Patches of pale olive-green alteration minerals thread through the upper matrix, giving the entire piece a beautifully weathered, authentic "alpine vein" aesthetic.​Perfect for serious regional collectors, Colorado enthusiasts, or as an educational display piece that tells a story of high-altitude geology.
