“…However, Saunders et al (2005) suggest that doming due to an ascending mantle plume ('Siberian plume') occurred in the area of the West Siberian Basin rather than beneath the thick and stable Siberian craton. Alternatively, the plume may have been intrinsically dense due to an abundant pyroxenite (eclogite) component, and this, associated with erosion of the base of the lithosphere by the plume, may have minimised surface uplift (Sobolev et al, 2011).…”

The Siberian large igneous province (LIP) forms the world's most extensive continental exposure of basalt and has several sub-provinces surrounding it, which may be genetically related. The Taimyr peninsula of north Siberia is one of these sub-provinces and is frequently assumed to be the northerly continuation of the basalts exposed at Noril'sk, the best-studied area of the Siberian LIP. However, the correlation is uncertain. The major and trace element data for both groups are consistent with a process of fractional crystallisation coupled with small degrees of assimilation of incompatibleelement-enriched lower crust involving different contaminants. Trace element model calculations indicate a process of magma formation at large degrees of partial melting and at pressures of less than 3 GPa, probably within the garnet-spinel transition zone or the spinel stability field of the asthenospheric mantle. We obtained an argon plateau age of ~252 (252.7 ± 1.5) Ma and a ~239 Ma total fusion age from a Taimyr lava and intrusive sample, respectively, confirming that volcanism is only partly contemporaneous with the activity of the Siberian LIP. Although this is in agreement with previous interpretations, we argue that the age difference between both events is only ~13 myrs and probably less (~5 myrs) although further investigation of the relationship is required. Our data allow correlation with distinct Noril'sk members and most importantly to the ore-bearing (Ni-Cu) intrusions implying that whole rock chemistry could have value as a prospecting tool in Taimyr.

“…4 remained virtually unchanged until the Permo-Triassic boundary as reflected by paleogeographic maps reconstructed through different stratigraphic ages (Vinogradov, 1968) (Podurushin, 2002). Saunders et al (2005), however, argued for a relationship between the uplift and a plume. The question whether the subsidence/uplift history recorded for Siberia is associated with a plume is considered in more detail below.…”

Various evidence, including size and volume of the Siberian Traps, timing and duration of eruptions, paleotectonic and paleogeographic reconstructions, lithospheric structure, heat flow, trace element and radiogenic isotope compositions of lava are reviewed in this chapter.The major evidence may be summarized as follows. The Siberian Traps erupted in a number of brief volcanic events from the Late Permian until the end of the Middle Triassic. They In radiogenic isotope and trace element coordinates, mixing trends between these two types of magma are absent or, at least, not evident. Some volcanic rocks contain primary magmatic mica. These are considered in light of different models. Each model can explain, or was thought to explain, particular observations. However, some evidence can be fatal for some models. For example, the enormous size and volume cannot be explained in the framework of impact and edge-driven convection models, and is problematic for lithospheric delamination models. Plume models face problems explaining the uplift/subsidence pattern and the absence of mixing curves between expected high-Ti primary plume melts and contaminated low-Ti

“…Basaltic magmatism was co-incident with -and possibly promoted by -rifting in 33 the West Siberian Basin, which continued to a poorly-constrained time in the Triassic 34 (Saunders et al 2005). The West Siberian Basin covers ~2.5 x 10 6 km 2 , located over 35 basement created or assembled in the Altaid orogeny (Şengör & Natal'in 1996).…”

We use magnetic intensity data to determine the geometries of basalt-filled rifts of the West Siberian Basin. En echelon graben arrays suggest a component of right-lateral, north–south shear during east–west extension (present co-ordinates). Several major exposed faults at the basin margins, mainly within the Altaid orogenic belt, underwent right-lateral strike-slip in the Late Permian–Early Triassic interval. The combined datasets show that the Siberian flood basalts were erupted during right-lateral oblique extension between the Urals and the Siberian craton, centred on a triple junction in the NE of the West Siberian Basin.
