Jul 26, 2022 (Q Unknown) - Thin sections of the peridotite are composed of serpentine, relict olivine, pyroxene, chlorite, green spinel, and opaque minerals. The olivine is much fractured and cut by serpentine veinlets carrying fine opaque minerals. The peridotite is cut by veins of olivine-grey deweylite, a variety of serpentine that has the conchoidal fracture and the appearance of chert but is much softer. In places, mica is present in the peridotite.
