Calcite
Crystal Cavern, Terlingua Mercury District , Brewster Co., Texas, USA
9.5 cm X 10 cm.
Calcite, rhombohedral and zoned, same location. 9.5 cm X 10 cm. This is an example of the calcite that coats the walls, ceiling, and floor of the Crystal Cavern. The Terlingua Mercury District is characterized by breccia pipes, collapse breccias that formed just a big jumble of limestone boulders. Caves are not uncommon in the mines of the district. Lots of open cavities means good collecting. (Author: Ed Huskinson)
