Paleotemperature indicators and apatite fission track analysis of Australian continental margin cover sequeRces accreted to the active Banda arc-continent collision indicate little to no heating during rapid late Neogene uplift and exhumation. Thermal maturation patterns of vitrinite reflectance, conodont alteration and' illite crystallinity show that peak paleotemperatures (PPT) increase with ...

Becker et al. (1) presented geochemical evidence that suggests that the largest mass extinction in Earth history, at the PermianTriassic boundary (PTB) 250 million years ago (Ma), coincided with an extraterrestrial impact comparable in size to the one that likely caused the end-Cretaceous extinctions 65 Ma (2). Although Becker et al. analyzed material from sections in Hungary, Japan, and China,...

Cycle stratigraphic and magnetostratigraphic analyses of a -5000-m-thick composite section obtained by scientific coring in the Newark rift basin of eastern North America provide a high-resolution astronomically calibrated geomagnetic polarity timescale (GPTS) spanning over 30 m.y. of the Late Triassic and earliest Jurassic. Only normal polarity is found in -1000 m of interbedded volcanics and ...

The protracted recovery of marine ecosystems following the Permian–Triassic mass extinction may have been caused, in part, by episodic environmental and climatic crises during the Early Triassic, among which the Smithian– Spathian boundary (SSB) event is conspicuous. Here, we investigate the SSB event in the Shitouzhai section, Guizhou Province, South China, using a combination of carbonate car...
