Description

An unusual growth of calcite from the tin ore deposit otherwise known for exceptional green fluorite crystals. Pale yellow flat rhombohedral calcite grows homoepitaxially on the paper thin sheet of white calcite. The primary calcite is typical of high-temperature calcite and shows reticulated network of domains that look as if they are twinned. the odd thing is that the younger calcite generation is not twinned, but simply overgrows the calcite plate within. Younger calcite is nicely transparent and has a complex texture of sutures on the rhombohedral surfaces. I got this one at the Mineralien Tage in München in 2014.
