Pyotr Nikolayevich Kropotkin
His main publications were devoted to tectonics and its relationships with magmatism and to tectonigeophysical problems. He developed the theory of the Earth's outgassing and abyssal inorganic origin of petroleum and coined the terms "cold outgassing" as well as "degassing column" later known in the West as chimneys concept.
Kropotkin graduated from Moscow Geoexploration Institute (MGRI) in 1932. He took part in prospecting for oil in the West Urals. Since 1936 he was with Geological Institute of Russian Academy of Sciences (RAS). He was elected a RAS Academician in 1992 and was awarded the Demidov Prize in 1994.
