The first data on the silver content in volcanics of the West Siberian Plate are presented, and data on basalts of the Siberian Platform are supplemented. The silver contents in all studied rocks do not depend on the fractionation of initial melts an

We present new high-precision 40Ar/39Ar ages on feldspar and biotite separates to establish the age, duration and extent of the larger Siberian Traps volcanic province. Samples include basalts and gabbros from Noril'sk, the Lower Tunguska area on the

The Oneka intrusive complex, recognized on prospecting for hydrocarbons in the western Siberian Platform, in the northern half of the Bakhta megablock (Tunguska syneclise), holds a special position among the known and new large-scale manifestations o

The lava sequence of the Alag-Zaar-Gol River catchment (southern Hövsgöl area, northern Mongolia) is an accretionary prism composed of metamorphosed basalt and, less often, andesite alternating with siliceous tuff. The protolith of metabasalts may

New major and trace element data for the Permo–Triassic basalts from the West Siberian Basin (WSB) indicate that they are strikingly similar to the Nadezhdinsky suite of the Siberian Trap basalts. The WSB basalts exhibit low Ti/Zr (~50) and low hig

Widespread basaltic volcanism occurred in the region of the West Siberian Basin in central Russia during Permo-Triassic times. New 40 Ar/ 39 Ar age determinations on plagioclase grains from deep boreholes in the basin reveal that the basalts were eru

Five of six samples representing the entire stratigraphic sequence (∼3700 m thick) of basaltic flows in the Noril'sk section in the northwestern part of Siberian flood basalt province, Russia yield 40 Ar– 39 Ar plateau ages between 248.3±1.7 Ma
