Mineral Specimen #5331    Hexagonal Calcite partially Pseudomorphed to Malachite on Chalcopyrite Pseudomorph Casts after Galena

Sweetwater Mine, Viburnum Trend Dist., Reynolds Co., Missouri

This specimen exhibits two types of pseudomorphs. The base is composed of small Chalcopyrite crystals which formed over Galena crystals. The Galena crystals are no longer extant leaving a cast. Some of the Calcite has partially altered to Malachite due to substitution of calcium with copper with the Chalcopyrite being the probable source of the copper.

Condition: Good

Flaws: Two of the side faces of the largest crystal show extensive contact surfaces (see the 4th picture).

3.6 x 3 x 3.1 cm
