A Shallow‐Marine Ecosystem Before Initial Tibetan Plateau Uplift

Abstract The uplift of the Tibetan Plateau profoundly influences global atmospheric circulation, sediment transport, and biodiversity, but its pre‐uplift marine paleoenvironment remains poorly understood. Here we report the first discovery of an in situ benthic fossil assemblage...

The role of equatorial juvenile arcs in the Middle Triassic seawater 87Sr/86Sr decline during the Pangean “quiet” period

The Middle Triassic (246−235 Ma) seawater 87Sr/86Sr record exhibits an excursion following the recovery from Siberian large igneous province volcanism. Two primary mechanisms have been proposed to explain the isotopic shift: (1) a change in the 87Sr/86Sr ratio of the continental...
