1953. 4to, pp. 34; with a number of 11 text figures and 16 tables; lightly browned; stapled as issued in the original printed wrappers, evidence of previous label on lower rear cover. A later paper by the noted Russian born geologist and chemist, Taisia Maximova Stadnichenko (1894-1958), considered one of the foremost geochemists in her field, and whose work focused on the distribution of germanium and the minor-element content in coal. Born in Taganash in the Crimea, she attended Petrograd University before joining the Russian Geological Survey as a chemist, and was part of a surveying expedition to the Island of Sakahalin in 1917. During WWI she moved to the US as an interpreter for the Russian Mission, and remained as a representative to the Washington Disarmament Peace Conference after the war. After the war, she continued her professional life as a researcher at the University of Illinois and as a professor at Vassar College from 1922 to 1935. In 1935, Stadnichenko led the first U.S Geological Survey exploring the minor-element distribution within coal by collecting samples of coal ash for element content analysis, which found germanium and other elements within the coal ash. Stadnichenko is widely considered instrumental in the discovery and understanding of coal's structure and origin.
