Vadim A. Kravchinsky (born in Irkutsk, Russia) is a Russian-Canadian geophysicist. He graduated with a bachelor's degree in geophysics at the Irkutsk National Research Technical University.

He started as an engineer-geophysicist working in the Irtutsk Geophysical Expedition (industry) and defended his PhD thesis in 1995.[1] He became a Director of the Irkutsk Paleomagnetic Laboratory in 1996. He moved to the Institut de Physique du Globe de Paris (France) as an invited professor and CNRS researcher in 1997.[2] Kravchinsky joined the geophysics group of the Department of Physics at the University of Alberta in 2021, where he became a professor of physics in 2002.[3] In 2003, Kravchinsky obtained a Canadian Foundation for Innovation grant to build a laboratory of paleomagnetism and petromagnetism.[4][5] His research interests are in the areas of geophysics, paleomagnetism and archeomagnetism, plate tectonics, climate and paleoclimate, and numerical modelling of geophysical and environmental processes.[6]

Kravchinsky and his graduate students and research associates led field trips in Canada, China, France, Mexico, Mongolia, Scotland, Siberia, and the United States.[7] They published manuscripts on plate tectonics and paleomagnetism of Eurasia and North America, magnetostratigraphy, astrochronology and cyclostratigraphy, archeomagnetism and geomagnetism, geophysics theory and time series analysis.[8]

Kravchinsky reconstructed the size of the Mongol-Okhotsk Ocean and the surrounding continents based on the paleomagnetic data from the Mongol-Okhotsk suture zone.[9][10] His colleagues and he published the longest continental lacustrine climate and geomagnetic records from the deepest lake on Earth, Lake Baikal.[11][12] He was the first to suggest that mass extinctions in the Paleozoic Era were related to the giant volcanic events recorded in the Large Igneous Provinces.[13][14][15] With his co-authors and students, Kravchinsky further developed the quantitative reconstructions of continents, calculating not only their paleolatitudes but also their paleolongitudes[16][17][18] and determining the age of geological events using paleomagnetic dating technique.[19]
