Abstract

Abstract

The East China Sea Shelf Basin is a Mesozoic and Cenozoic oil-gas-bearing basin located at the juncture of the subduction zones of the Philippine Sea plate and the Indian plate, in particular in the period of Cenozoic. The indentation of the Indian plate under the Eurasian plate caused extrusion tectonics in the Eurasian Plate. The mantle flow under both the Indian plate and the south China block flowed southeastward through mantle flow channels under the Eurasian plate, that made the mantle upwelling and crust rifting in East China. The subduction of the Indian plate has a long-distance impact to the East China Sea Shelf Basin. The tectonic phenomena observed in this region, such as the retrogression of subduction zones, the increase in subduction angle of the Philippine Sea plate, and the tectonic inversion, the migration of tectonic center and depocenter, and the structural jumping from the west to the east in the East China Sea Shelf Basin, owed their origin to the impact of Indian Plate.
