CRYSTAL FRACTIONATION IN THE PETROGENESIS OF AN ALKALI MONZODIORITE-SYENITE SERIES: THE OSHURKOVO PLUTONIC SHEETED COMPLEX, TRANSBAIKALIA, RUSSIA

Litvinovsky B.A.; Shadaev M.G.; Zanvilevich A.N.; Jahn B.-M. (2002)

The Oshurkovo Complex is a plutonic sheeted complex which represents numerous successive magmatic injections into an expanding system of subparallel and subvertical fractures. It comprises a wide range of rock types including ...
FORMATION STAGES AND SOURCES OF THE PERALKALINE GRANITOID MAGMATISM OF THE NORTHERN MONGOLIA-TRANSBAIKALIA RIFT BELT DURING THE PERMIAN AND TRIASSIC

Yarmolyuk V.V.; Kovalenko V.I.; Zhuravlev D.Z.; Litvinovsky B.A.; Zanvilevich A.N.; Posokhov V.F.; Jahn B.-M.; Vorontsov A.A.; Sandimirova G.P.; Kuz'min D.V. (2001)

Rb-Sr and Sm-Nd isotopic systems were investigated in the peralkaline granitoids and comagmatic volcanic rocks, which compose the Northern Mongolia-Transbaikalia Belt (NMTB). The belt extends over more than 2000 km at a ...
GEOCHEMICAL AND ISOTOPIC STUDIES OF THE SEDIMENTARY AND GRANITIC ROCKS OF THE ALTAI OROGEN OF NORTHWEST CHINA AND THEIR TECTONIC IMPLICATIONS

Chen B.; Jahn B.-M. (2002)

The Altai orogen (northwest China) represents the southwestern margin of the Central Asian Orogenic Belt. Geochemical and Nd3.4 to 1.8 Ga, and ISr = 0.7106 to 0) and ISr (0.7110.7051). Voluminous syn-orogenic granitoids ...
PETROGENESIS OF SYENITE-GRANITE SUITES FROM THE BRYANSKY COMPLEX (TRANSBAIKALIA, RUSSIA): IMPLICATIONS FOR THE ORIGIN OF A-TYPE GRANITOID MAGMAS

Litvinovsky B.A.; Zanvilevich A.N.; Jahn B.-M.; Poulain S.; Saunders A.; Reichow M.K.; Kuzmin D.V.; Titov A.V. (2002)

Two syenite–granite suites, metaluminous and peralkaline, that form the Bryansky Complex in Transbaikalia, Russia, have been studied with the aim to constrain the existing models of A-type granitoid magma generation. The ...
SOURCES OF PHANEROZOIC GRANITOIDS IN THE TRANSECT BAYANHONGOR-ULAAN BAATAR, MONGOLIA: GEOCHEMICAL AND ND ISOTOPIC EVIDENCE, AND IMPLICATIONS FOR PHANEROZOIC CRUSTAL GROWTH

Jahn B.-M.; Capdevila R.; Vernon A.; Liu D.; Badarch G. (2004)

The Central Asian Orogenic Belt (CAOB) is renowned for massive generation of juvenile crust in the Phanerozoic. Mongolia is the heartland of the CAOB and it has been subject to numerous investigations, particularly in ...
