STRAKHOV, NIKOLAI MIKHAILOVICH (Geologist) 



N. M. Strakhov was born April 15, 1900. In 1928 he gradu- 

 ated from Moscow University. He began working in 1934 at the 

 Geological Institute of the U.S.S.R. Academy of Sciences. In 1953 

 he was made a member of the main editorial staff of the Bol' - 

 shaya Sovetskaye Entsykl. (Great Soviet Encyclopedia). He was 

 elected a Corresponding Member of the U.S.S.R. Academy of 

 Sciences in 1946, and in 1953 an Academician. In 1948 he was 

 awarded a Stalin Prize. 



Strakhov' s scientific activity is in the field of modern de- 

 posits, ancient sedimentary rock— iron ore, lime-dolomitic 

 rocks, oil shale, halogen deposition, and of the geochemistry of 

 iron, manganese, phosphorus, vanadium, chromium, nickel, and 

 a series of other elements. Continuing the work of his teacher, 

 A. D. Arkhangel' skii (1879-1940, geologist, professor at Mos- 

 cow University, and Academician), Strakhov developed and es- 

 tablished a comparative method of analysis in lithology. A 

 study of contemporary reservoirs (Black and Caspian Seas, 

 Lake Aral, Balkash and others) was made and an exact analysis 

 of contemporary sedimentation was presented. He studied the 

 role of diagenesis in the formation of sedimentary rock. He 

 published monographs on iron ore and lime-dolomitic species 

 of modern and ancient reservoirs and discovered new regulari- 

 ties in the formation of iron and carbonate rocks. He defined 

 the characteristics of sedimentation by the main structural 

 units of the earth's crust— platforms, geosynclines and the fore- 

 most depressions. He suggested a scheme of irreversible evo- 

 lution in sedimentary rock formation during the history of the 

 earth, and indicated three important stages: Pre-Cambrian, 

 the Proterozoic-lower Paleozoic, and the modern (from the 

 Devonian to the present). In addition, he associated the peri- 

 odic recurrence of similar rocks with the recurrence of major 

 transgressions and regressions of the sea. Recently he
