The New Hypothesis of the Origin to the Emeishan LIP: Because of the “Collisions Aggregation Effect” of a Meteorite Impact

Abstract

Emeishan LIP is the only accredited continental flood basalts (CFB) by domestic and international currently in China, there were a lot of explanations about its origin and based only on the petrology, chemistry, most believe its cause of formation is a "mantle plume", but just stay in the geochemical basis, there is no more convincing evidence. This article combined with the experiments and data demonstrate the truth and universality of the "Collisions Aggregation" theory, and think that there was a violent planetary collision occurred in the other side of the earth (the point of impact), the collision caused "Collisions Aggregation" effect and aroused a huge impact energy aggregated in the collisions aggregation point and earthquakes, volcanic activity and massive lava overflowed, the impact point and the collisions aggregation point were at the corresponding points of the ends of the earth through the geocenter, the impact and large-scale magmatism occurred almost simultaneously. The author believe that the Emeishan basalts may not be "mantle plume" caused, which broke lithosphere formed overflowing may not by the dome rising or crust thinning or rift valley of the dome head effect of the "mantle plume", but may be form a rising channel caused by "Collisions Aggregation" effect on account of a violent asteroid impact at the P/T historical periods of the earth, and the thermal fluid overflow because of external disturbances. Meanwhile, this article also explore the dynamic mechanisms of the "mantle plume" and make the role of better ideas to explore the relationship between the distribution of the hot spots in the surface of the earth and the asteroid impact events and the global mass extinction events.
