In 2015 and 2018, the author put forward the new hypothesis of the origin to the Emeishan LIP based on the “Collisions Aggregation Effect” of a Meteorite Impact. Under the guidance of this hypothesis, the author and his team collected a large number of domestic and international researches on Emeishan LIP and paleogeography, it is concluded that: 1. The main eruptive period of ELIP is at the P/Tr boundary period, about 257Ma. Its main distribution is located at 4°S, 152°E or 4°S, 110°E, located in YZ Block of the Southwest China, and is the marine facies eruption. 2. Based on the “Collisions Aggregation Effect”, the author proposed that the "impact point" is located in the 4°N, 28°W or 4°N, 70°W at the P/Tr boundary period, and is the marine sedimentary environment; 3. Combined with the "impact point" paleogeographic location, put forward located in the Atlantic Ocean of the northeastern Brazil or Colombia now; 4. The author believes that the"impact point" just in the oceans at the P/Tr boundary period, It is possible that the "impact point" of a meteorite is located exactly in the Panthalassic Ocean, resulting in an extensive regression, significant sea level declines, over 90% of marine life, and nearly 70% of the land extinction? 5. The authors will further study and analyze the evolution of the Panthalassic Ocean in the hope of gaining some ground from it, hoping to find evidence to verify the "impact point" and hope that interested researchers can join in to participate in the work.
