Density heterogeneity of the cratonic lithosphere: A case study of the Siberian Craton

open access: yesGondwana Research, 2015
Using free-board modeling, we examine a vertically-averaged mantle density beneath the Archean–Proterozoic Siberian Craton in the layer from the Moho down to base of the chemical boundary layer (CBL). Two models are tested: in Model 1 the base of the CBL coincides with the LAB, whereas in Model 2 the base of the CBL is at a 180 km depth.

Age of the Siberian craton crust beneath the northern kimberlite fields: Insights to the craton evolution

Gondwana Research, 2016
Abstract Comprehensive studies of zircon xenocrysts from kimberlites of the Kuoika field (northeastern Siberian craton) and several kimberlite fields of the eastern Anabar shield, along with data compilation on the age of kimberlite-hosting terranes, reveal details of the evolution of the northern Siberian craton.

Assembly of the Siberian Craton: Constraints from Paleoproterozoic granitoids

Precambrian Research, 2020
Abstract The paper presents a synthesis of geochronological, geochemical, and isotopic data on Paleoproterozoic granitoids in the Siberian craton and, in some cases, on volcanics related to these granitoids. Different evolution stages of the craton, including its assembly, are recorded in several major events in the history of Paleoproterozoic ...

The Early Cambrian bimodal magmatism in the northeastern Siberian Craton [PDF]

open access: yesRussian Geology and Geophysics, 2016
Abstract We present new data on geochemistry, isotopic geochemistry, and geochronology of the Early Cambrian igneous rocks of the northeastern Siberian Craton (Kharaulakh anticlinorium, contact between the Siberian Platform and the West Verkhoyansk sector of the Verkhoyansk fold-and-thrust belt united into an Early Cambrian bimodal ...
