Drusoid from the river Slyudyanka

Abstract

From the Museum of the Mining Institute, a sample No. 169/3 with the label: “Bronzite from the river Slyudyanka” was transferred for research in the Mineralogical Cabinet. Two thin sections made from it showed that the sample is a rock, which, in fact, contains, as a component, rhombic pyroxene, close to bronzite. The rock itself presents some features in its composition and structure, which force to attribute it to the type of drusite rocks.
