Detailed Mineral List:

ⓘ Andradite
Formula: Ca3Fe3+2(SiO4)3
Description: Demantoid are mostly found in chrysotile veins in a partly serpentinized peridotite. There are clear signs of hydrothermal/metasomatic alteration near the veins, indicating that the veins formed at relatively low PT conditions. Demantoid is found in 2-3m long veins. The demantoid are found as granular aggregates (up to 5 cm) intertwined into up to 20cm long chrysotile fibers. The individual demantoid aggregates are composed of small (less than a millimeter) grains in the central part and larger grains on the periphery. The intergranular space is filled with clinochrysotile (±lizardite?) and/or carbonate.
