We present the results of geostructural, mineralogic–petrographic, geochemical, and U–Pb geochronological investigations mafic, intermediate, felsic igneous rocks from dikes in Yana–Kolyma gold belt Verkhoyansk–Kolyma folded area (northeastern Asia). The Vyun deposit Shumniy occurrence intruding Mesozoic terrigenous Kular–Nera Polousniy–Debin terranes were examined detail. had diverse mineralogical petrographic compositions including trachybasalts, andesites, trachyandesites, dacites,...
We present new structural, petrographic, geochemical and geochronological data for the late Paleozoic–early Mesozoic granites associated igneous rocks of Taimyr Peninsula. It is demonstrated that large volumes were formed due to oblique collision Kara microcontinent Siberian paleocontinent. Based on U-Th-Pb isotope zircons, we identify syncollisional (315–282 Ma) postcollisional (264–248 varieties, which differ not only in age but also petrochemical features. shown as magmatism was coming an...
The geodynamic development of the north–western (Arctic) margin Siberian craton is comprehensively analyzed for first time based on our database as well analysis published material, from Precambrian-Paleozoic and Mesozoic folded structures to formation Mesozoic-Cenozoic Yenisei-Khatanga sedimentary basin. We identify main stages region’s tectonic evolution related collision accretion processes, mainly subduction rifting. It demonstrated that prototype basin was a wide late Paleozoic foreland...
Sedimentary successions and igneous rocks exposed in Eastern Sayan provide an important geological record on the tectonic evolution of southwestern margin Siberian Craton during Neoproterozoic. Here we present sedimentological detrital zircon provenance data from key stratigraphic units, complemented by a new U-Pb age 718 ± 6 Ma mafic Nersa magmatic complex. Sedimentological lower part succession (Karagasy Group) show that these were deposited passive setting after 750 before emplacement The...
Abstract We present a tectonothermal model for the late Paleozoic syncollisional formation stage of Kara orogen in northern Taimyr Central Arctic. The is based on new and published structural, petrological, geochemical, geochronological data, as well thermophysical properties obtained orogen. latter hosts significant volume granites formed result collision between microcontinent Siberian craton. Based geological, U–Th–Pb isotope were differentiated into postcollisional intrusions that...
