Some preliminary results of the study of melted rocks
Abstract
Random samples of thin sections of molten rocks, which were given to us by A. V. Vvedenskii, were studied. We did not aim at a systematic study of this random, though rather 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 are glasses that have just begun to recrystallize with the formation of spherulites or various kinds of skeletal formations. Only in a few thin sections could one find minerals individualized in such a form that they were amenable to optical examination. Therefore, the main task of the study was the study of structures, and a considerably smaller amount of work involved the study of minerals.
