| Ca2(Mg,Fe)5Si8O22(OH)2 - Occurs as translucent elongated prismatic crystals found as monomineralic aggregates, or associated with phlogopite or talc. Crystals are dark green and do not possess terminations. Actinolite in cores of ultramafic lenses are more translucent and brighter in color. |
CaCO3 - Occurs as opaque white to grey cleavable masses from decimeter scale monomineralic calcite lenses. | |
Mg3Si2O5(OH)4 - Occurs as chatoyant seams in ultramafic rock observed to about 1-inch thick. | |
Chromium (Cr) rich muscovite, KAl2(AlSi3O10)(OH)2 - Occurs as bright green schistose masses. | |
KMg3(AlSi3O10)(OH)2 - Occurs as bronze-colored schistose masses. | |
FeS2 - Occurs as cubes to about 2 cm embedded in silicic matrix. | |
SiO2 - Occurs as milky crystals up to about 2 cm in small cavities. | |
