Permian-Triassic flood basalts are widespread across an extremely large area of the Siberian plate in the pre-Jurassic basement of the West Siberian plate. We show that Permian-Triassic flood basalts are similar to the trap basalts of the Siberian Platform with regard to geochemical features and Pb, Sr and Nd isotopic composition. Strontium and neodymium isotope ratios indicate the contribution to the formation of the flood basalts of the EM1 reservoir. We will also show a possible contamination of basalt magma by the Palaeozoic island-arc and orogenic rock complexes.
