TL;DR: In this paper, the authors show that heating of Tunguska Basin sediments by ascending magma played a key role in triggering the end-Permian environmental crisis.

TL;DR: In this article, the authors use thermodynamic calculations to show that high-temperature interaction between magma and organic matter can lead to a dramatic reduction of the magma redox state, and significant departure from that of the original source.

TL;DR: In this article, the authors show that tuffs are virtually absent along a 150 km long transect along the Dyupkun lake and Kureika river, even though tuff is shown on available geological maps and the main thicknesses of explosive tuff, up to 700m, are located in the central and southern parts of the province where the LIP erupted through thick Cambrian salt and carbonate sequences.

TL;DR: The first high precision U-Pb zircon geochronology from two alkaline ultramafic-felsic layered intrusive complexes from Taimyr is reported, showing synchronicity between these and the main Siberian Traps (sub)volcanic pulse, and the presence of a second Dinerian-Smithian pulse.

TL;DR: In this paper, a detailed study of the breccias in the Sholokhovsk basalt pipe located within the Nepa potash deposit in the Tunguska Basin, Siberia, Russia (about N 59° and E 107°) was conducted.
