Late Permian coal deposits are widely distributed throughout southwestern China. This paper describes the petrological composition of last seam in Longmendong section Emeishan area during latest Changhsingian (Permian) and records important information regarding evolution mass extinction event that occurred at end Permian. The results show dominant maceral group is vitrinite, followed by liptin...

The paper considers the Pd/Pt ratio in ores of Norilsk-1 and Talnakh deposits associated with Permian-Triassic intrusions Norilsk type comparison that lavas same age region. mean is 1 2–4 times higher than barren horizons intrusions. Such an increase implies these elements were borrowed by magma from small medium-sized crust previous stage Permian island-arc volcanism.

The Permian–Triassic boundary (PTB) section at Guryul Ravine (Kashmir, India) comprises a N100-m-thick, apparently conformable succession of mixed siliciclastic–carbonate sediments deposited in a deep-shelf or ramp setting. This section, although long important in debates concerning placement of the PTB, has not previously been the focus of an integrated chemostratigraphic study. In the present...
