The Early Cambrian bimodal magmatism in the northeastern Siberian Craton

Russian 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 ...

Chapter 6.4 The Oldest Rock Assemblages of the Siberian Craton

2007
Publisher Summary This chapter elaborates the oldest rock assemblages of the Siberian Craton. The Siberian Craton that occupies an area of approximately 4 × 10 6 km 2 is overlain largely by Mesoproterozoic to Phanerozoic sedimentary rocks, whose thickness ranges between 1 and 8 km, averaging approximately 4 km.

Signature of Precambrian extension events in the southern Siberian craton

Russian Geology and Geophysics, 2007
Abstract We investigate extension events in the southern Siberian craton between 1.8 and 0.7 Ga. Signature of Late Paleoproterozoic within-plate extension in the Northern Baikal region is found in 1674 ± 29 Ma dike swarms. A Mesoproterozoic extension event was associated with intrusion of the 1535 ±14 Ma Chernaya Zima granitoids into the

Paleoproterozoic, High‐Metamorphic, Metasedimentary Units of Siberian Craton

Acta Geologica Sinica - English Edition, 2009
Abstract:Sensitive, high‐resolution ion microprobe zircon U–Pb ages of Paleoproterozoic, high‐grade, metasedimentary rocks from the south‐western part of the Siberian Craton are reported. Early Precambrian, high‐grade complexes, including garnet–biotite, hypersthene–biotite, and cordierite‐bearing gneisses compose the Irkut terrane of the Sharyzhalgay ...

Mesoproterozoic to Neoproterozoic Evolution of the Siberian Craton and Adjacent Microcontinents

2007
Abstract: Over the past decade several restorations of the hypothetical Mesoproterozoic to Neoproterozoic supercontinent have been suggested. In this paper, we summarize the most recent data on Mesoproterozoic to Neoproterozoic geology of the Siberian craton to test different restorations.
