Pseudomorph of quartz after calcite

One perfect cabinet size specimen, illustrating pseudomorph of quartz after calcite developed on quartz crystals. Pulsation of the mineralization process was fixed by developing several stages of mineralization of quartz on the top of steep calcite scalenohedron crystals.

Calcite ater calcite pseudomorph

A very attractive specimen of steep calcite scalenohedrons followed by thin quartz layers and covered with several portions of later generation of calcite. The crystals were broken by tectonic moves and later rehealed by transparent calcite.
