MESO-CENOZOIC EVOLUTION OF THE TANLU FAULT AND FORMATION AND DISTRIBUTION OF PETROLIFEROUS BASINS

A number of Meso-Cenozoic medium and large petroliferous basins in the peri-Pacific region in the eastern part of continental China are distributed on both sides of or inside the Tanlu fault.It is evident that the formation and evolution and distribution of these petroliferous basins are related to the development and evolution of the Tanlu fault.Based on an integrated analysis of the geological and geophysical data,the internal relations between the Tanlu fault and the formation and distribution of petroliferous basins were studied from the aspects of the distribution of petroliferous basins and their structural geometry,kinematics and dynamics.The author thinks that the sedimentary basins on both sides of the Tanlu fault belong to the fault system and is local derivative structures formed during the Meso-Cenozoic evolution of the fault system.
