Pyrite-after-Anhydrite with Galena
specimen number:
3261052
location:
Sweetwater mine, Viburnum Trend, Reynolds Co., Missouri, USA
description:
Collected in the very early 1990s, these kind of came and went in a hurry. A prismatic crystal of what was once anhydrite replaced by crystallized pyrite and topped off with a lustrous cubic galena crystal 0.7 cm on edge. There was always a question in the past whether this was truly after anhydrite, of late I had someone tell me they actually found relict anhydrite on one of these specimens. In great condition all around.
