| Abstract: | The Tancheng - Lujiang wrench fault system is one of the most important giant structural zones in Eastern China , which controls or affects the formation of many oil -bearing basins along it .In this article , the structural features and evolution of the Tancheng -Lujiang wrench fault system in Bohai Bay Area during the Cenozoic period , as well as the control of the fault activities on the evolution of sedimentary basin in this area , are discussed upon analyses of seismic expression across the fault system .Main views advanced in the article are as follows : (1 ) Even within the Bohai Bay Area , the structural characteristics of the Tancheng-Lujiang wrench fault system are different in Northern , Southern and Central Bohai ; (2 )The mainly active period of the fault system is the Early Tertiary , it is actually a right -lateral divergent-wrench fault system with a strong synsedimentary characteristic instead of a left-lateral wrench fault system or a purely extensional one ; (3 ) The oil-bearing basin in Bohai Bay Area is not a simply extensional basin as it was thought originally , the distribution of structural traps in the basin is different from those formed in a simply extensional basin , as is its pattern of oil and gas accumulation . |
