Description
This strange mineral has a very unusual surface covering of the sulfosalt boulangerite over a heavy sulfide matrix. The texture is unlike any other mineral - appearing like a thick mat of semi-metallic fur that has completely coated the host rock. These microscopic, capillary mineral hairs make the whole piece resemble a very weird, misshapen owl pellet or a chunk of an animal carcass!
