Dolomite (rare) w/ Calcite (classic locale) Trimingham Coll.

Item Description

Dolomite specimens are rare from this famous Greek locale, noted for for quartz prases included with green actinolite, not hedenbergite (Hyrsl and Niedermayr, 2003). Sharp, glassy, coloress, penetration-twinned dolomite crystals are sculpturally intergrown and have a nubby, tan iron oxide overgrowth. Preferentially deposited calcite rhombs with a sprinkling of rare, brassy pyrite crystals are a fine accent to this rare and excellent two-sided combination. A scratch test showed this to be dolomite, not calcite. Ex Bob Trimingham Collection.
