An explicit plate kinematic model for the orogeny in the southern Uralides

Geology and assessment of undiscovered oil and gas resources of the Northern West Siberian Mesozoic Composite Total Petroleum System of the West Siberian Basin Province, Russia, 2008

“…accreted to the surrounding cratonic areas ultimately led to the assembly of Pangea (Hamilton, 1970;Scarrow and others, 2002;Surkov and others, 2004;Vyssotski and others, 2006;Görz and Hielscher, 2010). The basement of the West Siberian Basin, along with parts of the Kazakh and Altay-Sayan uplifts, form what are called the West Siberian Altaids (Görz and Hielscher, 2010).…”

“…accreted to the surrounding cratonic areas ultimately led to the assembly of Pangea (Hamilton, 1970;Scarrow and others, 2002;Surkov and others, 2004;Vyssotski and others, 2006;Görz and Hielscher, 2010). The basement of the West Siberian Basin, along with parts of the Kazakh and Altay-Sayan uplifts, form what are called the West Siberian Altaids (Görz and Hielscher, 2010). By Permian time the basement of the West Siberian Basin was a coherent entity, but the heterogeneous nature of the basement formed a zone of crustal weakness compared to adjacent cratonic areas (Aplonov, 1995;Scarrow and others, 2002), and this weakness figured prominently in the subsequent location of the West Siberian Basin.…”

“…Exposures in the Urals represent rock assemblages that are similar to those within the basement of the West Siberian Basin, and the Uralian orogenic belt extends beneath the basin (Ulmishek, 2003). The complex convergent tectonic history of the Uralian orogenic zone is well known and many studies have documented the rock assemblages formed during closure of the various paleo-oceans (Savelieva and Nesbitt, 1996;Brown and others, 1997;Juhlin and others, 1998;Ayarza and others, 2000;Scarrow and others, 2002;Puchkov, 2009;Brown, 2009;Görz and Hielscher, 2010). The Novaya Zemlya fold belt ( fig.…”

“…1). The motion of the Novaya Zemlya fold belt was accommodated along regional bounding faults (Otto and Bailey, 1995;Görz and Hielscher, 2010). Following the ultimate closure of the various oceanic basins between the Uralian orogenic belt and terranes in the late Carboniferous and early Permian, the area of the West Siberian Basin apparently was emergent, as there are no preserved Permian sediments (Friberg and others, 2002;Saunders and others, 2005).…”

The early Precambrian history of rock metamorphism in the Urals segment of crust

“…However, in recent years, geochemical and isotopic data have been obtained demonstrating that the protolith of the East Uralian zone may be primarily oceanic crust and gneisses that do not contain Palaeozoic granites but rather constitute the boundaries of granite massifs (Görz et al 2009;Görz and Hielscher 2010).…”
