Calcite with Bornite

A solitary double terminated scalenohedral Calcite measuring 5 cm long is perched at about 30 degrees to a long and flat bed encrusted with mm sized Calcite crystals.  The large Calcite is dusted with micro-granular golden-bronze Chalcopyrite and the Calcite bed is strewn with Bornite crystals. The latter divide into two categories: sub-mm crystals of mainly iridescent peacock-blue and larger crystals, typically between 2 and 5 mm broad, of iridescent metallic golden-lime-green.
