This is a specimen of hydroxylapatite. It is present as a pale yellow and translucent crystalline crust on top of an opaque white botryoidal crust over a brown host rock. The hydroxylapatite crystals have a form that is difficult to describe. The curface is not botryoidal, because each dome consists of several nearly flat terminations that are only rounded in the agregate. It reminds me of some skutterudite specimens, although the individual crystals are quite small.
