Superb Siderite Epimorph After Calcite
Broken Hill Mine, North Cape Province, South Africa
An epimorph is a type of pseudomorph where one mineral replaces another mineral and the original mineral dissolves, leaving a hollow cast surrounded by the new mineral. The present specimen is an exemplary one, with an excellent horizon line, comprising five inter-grown crystals. Rich tan Siderite completely replaced the scalenohedral Calcite crystals with their flat tips. The specimen is complete overall. Measuring 7 x 3 1/2 x 2 1/2in
