Metamorphic Rocks and Minerals
Axinite is a complex calcium iron borosilicate mineral typically found in contact and regional metamorphic rocks. It is known for its unique wedge-shaped crystals, glassy luster, and brown to violet coloration. The variety found at New Melones in Calaveras County, California, is especially prized by collectors. Axinite often forms in skarn deposits, where hot, mineral-rich fluids interact with carbonate rocks, making it both a geologically informative and visually appealing mineral.
