A REVIEW OF EARLY PERMIAN (300–270 MA) MAGMATISM IN EASTERN KAZAKHSTAN AND IMPLICATIONS FOR PLATE TECTONICS AND PLUME INTERPLAY
Autor: S. V. Khromykh, P. D. Kotler, A. E. Izokh, N. N. Kruk
Publikováno v: Геодинамика и тектонофизика, Vol 10, Iss 1, Pp 79-99 (2019)
The history of the Central Asian Orogenic Belt (CAOB) was marked by several major events of magmatism which produced large volumes of volcanic and intrusive (mafic-ultramafic and granitic) rocks within a relatively short time span (30–40 Ma) over a

Metabasalts of Greenstone Belt of the Bulun Terrane (Southwestern Siberian Craton) as Indicators of Compositional and Isotopic Features of Archaean Mantle
Autor: A. D. Nozhkin, A. E. Izokh, O. M. Turkina
Publikováno v: Petrology. 29:315-335
The paper summarizes major, trace, and Sm-Nd isotopic data on metabasites of the Urik greenstone belt (GB) (Sharyzhalgai uplift, southwestern Siberian craton). The Archean metabasalts (amphibolites and garnet amphibolites) of the supracrustal complex

Ultramagnesian Olivine in the Monchepluton (Fo96) and Pados-Tundra (Fo93) Layered Intrusions (Kola Peninsula)
Autor: Andrei Y. Barkov, Robert F. Martin, Vladimir N. Korolyuk, Andrey A. Nikiforov, Andrey E. Izokh
Publikováno v: Russian Geology and Geophysics. 62:324-338
—The paper focuses on compositional variations of olivine and chromian spinel in the Monchepluton and Pados-Tundra layered intrusions, which host significant chromitite mineralization. Ore-bearing dunite (with up to 25–30 vol.% Mcr) in the Sopche

Thermomechanical Modeling of the Formation of Multi-Сhamber Intrusions for Identifying the Relationship of Plutonic Metamorphism with Gabbro-Diorite Massifs of Western Sangilen, Tuva, Russia
Autor: R.A. Shelepaev, Andrey E. Izokh, V.V. Egorova, A. N. Semenov, O. P. Polyansky, A. Yu. Selyatitskii
Publikováno v: Geotectonics. 55:1-19
For the first time, a thermomechanical model of a system of multilevel magma chambers above a mantle heat source has been developed to explain the formation mechanisms of intrusive complexes and metamorphic aureoles in Western Sangilen. A model of
