Calcite, Quartz, Dolomite on Fluorite     Dongshan Mine, Hunan Province, China.  On this piece we see tan dolomites with white calcite on clear to white quartz crystals.  All of these have heavily coated green fluorite.  The thin "slices seem to be where there were once bladed barite crystals or possibly anhydrite (now all gone with only their molds remaining).  No damage.  It measures 11.5 x 8.3 x 5.7 cm.  $40
