Record Type: Object
Calcite
Single, terminated calcite crystal with small, globular prehnite masses ringing the base of the calcite crystal. Crystal appears to have broken off from a larger matrix, as evidenced by massive inclusions at the base, but the prehnite is intergrown with the calcite and separated as well. Calcite is almost transparent with several inclusions. Crystal faces have some striations, and a vitreous luster.
