Barite from the Kerch mines

Abstract

In the summer of 1901, I managed to inspect the Kerch mines, where I obtained a fragment from a large barite specimen with the note that it was found in a mine located near the plant. The specimen in its original size was about 2 kilos in weight and had the shape of a mushroom; completely dense both in its central part and at the edges; wax-yellow in color with a white streak, translucent in small pieces and transparent in thin fragments; the pereferical layer about 3 mm thick is yellowish-white and cloudy. The structure is radiant. March 20, 1909
