THE DEEP PROCESS AND PALEOZOIC PETROLEUM PROSPECT OF THE BASINS BY THE SIDE OF QINLING-DABIE OROGENIC BELT

The deep geophysical survey information was applied to the description of the deep geologic structures and tectonic features of the lithosphere in East Qinling-Dabie orogenic belt.Researches show that the lithospheric tectonics control the deep processes of different basins related to orogenic belts and the tectono-stratification of lithospheric media and tectono-thermal events are in control of basining.The main characteristics of the relationship between lithosphere structure and petroleum prospect within this area are the lithosphere being laterally blocked and vertically decoupled,the asthenosphere mantle upwelling and thin layer crust,the deep processes with plastic deformation of the lithosphere and continent deeply underthrusting and tectonic decoupled as well as the deep thermal fluids upwelling to control the forming and migrating of the Paleozoic petroleum.
