inspecting a collection of calcite crystals.
At this location
one could expect to find Goethite, Quartz, Calcite, Rhodochrosite and
other manganese minerals.

Detail of Rhodochrosite
Iron stained quartz
crystals with minor Baryte and calcite.
Most of the calcite on this piece has been etched away to reveal the
encrusted with clear and smoky, double terminated quartz crystals
to about 3mm with a small group of baryte on the tip.

A small cavity
lined with clear quartz crystals with a few micro-goethites attached.
More barytes with
small "stalagmites" of goethite,
again encrusted with tiny double terminated quartz crystals.
A close up
of some tiny goethite growths with Baryte in the background.
example showing the iron stained quartz crystals embedded
with calcite and other minerals in a definite layered growth pattern.
