Petrology of Polygenic Mafic-Ultramafic Massifs of the East Sakhalin Ophiolite Association (eBook, ePUB)

• Format: ePub

Produktbeschreibung

The well-known concept of plate tectonics long dominated notions of stratified structure of ophiolite associations and overlap gabbroides on ultramafites. This book presents data that does not agree with these views and suggests an earlier introduction of protrusions of ultramafic upper mantle restites against the intrusions of gabbroides breaks, and their parent melts are actively working on ultramafic and convert them. This work presents new evidence of polychronic and polygenic formation of complex mafic-ultramafic massifs and various mechanisms of the formation of their rocks.

Autorenporträt

Felix P. Lesnov is Doctor of Geology and Mineralogy, Leading Research Fellow of the Sobolev Institute of Geology and Mineralogy, Siberian Branch of the Russian Academy of Sciences, and Member of the Russian Academy of Natural Sciences. He specializes in research on mafic-ultramafic complexes of folded areas (geology, petrology, petrochemistry, geochemistry, mineralogy, isotope geochronology, and chromite and Pt contents). The main study areas are the Chukchi region, Kamchatka region, Sakhalin Island, Primorye, northern Baikal region, eastern Transbaikalia, East and West Sayan, Tuva, Urals, Kyrgyzstan, Tajikistan, Mongolia, and Brazil. Felix Lesnov has (co-)authored more than 300 works, including more than ten monographs.
