Geo 730: Jan. 21, Day 386: Sepentine In Situ

Another one of Dana's photos, this shows how the serpentine appears in the outcrop. There are innumerable criss-crossing shear zones, and the serpentine fills those faults, to a greater or lesser thickness. Where it's thicker- say, on the order of a millimeter or more- one can often pry the translucent mineral away from its host rock. The host rock here is also mostly serpentine, but microcrystalline, and pretty dull.
