Dolomite Pseudomorph After Calcite

ID: CC1286

Large platy crystals of Calcite have been completely replaced by creamy Dolomite, an uncommon specimen from the Bere Alston Mines, Devon. The original crystals of Calcite have grown in a stepped form in sub-parallel habit, the largest crystal measuring to 8cm. A crystal druse of rhombic Dolomite with a pearly lustre covers the surface of the 'Calcite' crystals and a scattered dusting of light brassy yellow pyrite is seen on the Dolomite. A colourless to slightly yellow Fluorite with Pyrite is the matrix for the pseudomorphed Calcite crystals. An uncommon specimen from the mines.
