The Origin Of Continents And Ocean Basins by M. V. Muratov

Professor Mikhail Muratov, P.Sc., Corr. Mem. USSR Acad. Sci., is Head of the Chair of Regional Geology and Paleontology, Moscow Institute of Geological Prospecting. He is the winner of State and Lenin Prizes.

This book deals with the origin, structure, and tectonic behavior of the earth’s crust beneath continents and oceans and describes principal stages of the earth’s geologic history. The author attaches much importance to geosynclinal cycles and their role in continental crust build-up and discusses intri­guing hypotheses explaining the present day face of our planet.

Translated from the Russian by V. Agranat

Acidification des océans : la limite est franchie

« L’acidification des océans, conséquence directe de l’excès de CO2 atmosphérique, menace les équilibres marins. Identifié au début du millénaire, ce phénomène continue de questionner la recherche : quels en sont les effets, comment les étudier, et peut-on encore inverser la tendance ? »
