Abstract: The late Permian Emeishan Basalt Formation of SW China is one of Earth's LIPs (large igneous provinces), yet its basic geology remains poorly documented. Recent work on sections close to the type area in Sichuan Province enable us in part to rectify this. Descriptions of the formation and associated units at two areas, one on the lower flanks of Mt Emei and another from a series of outcrops in Ebian County, 50-70 km to the SW, are presented. The basalt pile is 180-270 m thick and in both areas comprises 12 flows that were erupted in relatively quick succession. It rests conformably upon shallow-- marine limestones/lignites suggesting emplacement close to sea level. The upper half ...
