Abrupt chemical weathering increase across the Permian–Triassic boundary

Previous studies have suggested a variety of causes for the end-Permian extinction event including a bolide impact, flood basalt volcanism, methane clathrate dissociation, or some combination of catastrophic processes. One common feature of these hypotheses is the prediction of an enhanced earliest Triassic greenhouse. New high-resolution geochemical results from Graphite Peak, Antarctica suppo...

The Permian–Triassic boundary in Antarctica

The Permian ended with the largest of known mass extinctions in the history of life. This signal event has been difficult to recognize in Antarctic non-marine rocks, because the boundary with the Triassic is defined by marine fossils at a stratotype section in China. Late Permian leaves (Glossopteris) and roots Vertebraria), and Early Triassic leaves (Dicroidium) and vertebrates (Lystrosaurus) ...

The Permian–Triassic boundary crisis and Early Triassic biotic recovery

This issue of Palaeogeography Palaeoclimatology Palaeoecology is devoted to papers on the Permian– Triassic boundary crisis and Early Triassic biotic recovery. It is an outgrowth of the Symposium on Early Triassic Chronostratigraphy and Biotic Recovery that was held in Chaohu, China, on May 21st–23rd, 2005 under the auspices of IGCP Project 467 and attended by about 200 Earth scientists with a ...

PERMIAN-TRIASSIC BOUNDARY OF INDIAN SUBCONTINENT AND ITS INTERCONTINENTAL CORRELATION

The Permian-Triassic boundary in the Himalayas is reviewed and discussed in the light of palaeontologic and stratigraphic data collected during the past two and a half decades from Kashmir, Spiti and Nepal. The deposition of the Kuling Shales and their equivalents in different parts of the Himalayas was followed by shallowing and regression of the sea. Sedimentation was interrupted at the t...
