Geology and Minerals
The Emeishan Traps is a flood basalt volcanic province, or large igneous province located in south-western China, centred in Sichuan province. It is sometimes referred to as the Permian Emeishan Large Igneous Province or Emeishan Flood Basalts. It is named after Emeishan, a mountain located in the Sichuan province. Like other volcanic provinces or "traps", the Emeishan Traps are multiple layers of igneous rock laid down by large mantle plume volcanic eruptions. The Emeishan Traps eruptions were serious enough to have global ecological and paleontological impact being associated with the Capitanian mass extinction.
