Some preliminary results of the study of melted rocks

Abstract

We studied random samples of thin sections of melted rocks, which were given to us by A.V. Vvedenskii. We did not pursue the goals of a systematic study of this random, although quite extensive (about 200 thin sections) material, and in this note we limited ourselves to only some data, characterizing the more common types of these "artificial rocks". The vast majority of the studied thin sections represent glasses that have just begun to crystallize with the formation of spherulites or various kinds of skeletal formations. Only in a few thin sections could one find individualized minerals in such a form that they were amenable to optical examination. Therefore, the main task of the study was the study of structures, and much less work was the study of minerals.
