Through field study of the sponge reefs in Jushui of Anxian and the sections in Ma’antang of Jiangyou, Shangsi of Guangyuan and Hanwang of Mianzhu, the authors think that the sponge reefs in the frontal region of the oft-com:office:smarttags" />Longmenshan Mountains grew in the deeper water body with complex landform and with low energy. In the Longmenshan Mountain area, the sponge reefs are overlain by black mudstone (shale) and silty mudstone and the boundary is obvious. This set of Carnian mudstone is distributed stably over West Sichuan Province and implicates the Carnian Pluvial Event. The death of the sponge in the Jushui area was triggered by this event which was influenced by megamonsoon and the input of terrigenous materials.oft-com:office:office" />
