Chirvinskii’s main works dealt with such fields as mineralogy and petrology, geochemistry, paleohydrogeology, the study of useful minerals, and the history of science. Chirvinskii was the first to determine the average chemical and mineral composition and atomic structure of granites and other plutonic rocks (1911), of the earth as a whole (1919), and of meteorites. He ascertained the laws governing the crystallization of plutonic rocks and meteorites. He also explained the origin of a number of deposits of various minerals, such as iron ores, phosphorites, tuffs, and potassium salts.
