AN UNDERSTANDING OF TENSE-SHEARING AND COMPRESSO-SHEARING STRUCTURES IN BOHAI BAY BASIN
对渤海湾盆地张扭、压扭性构造的一点认识

The structural manner studying provides a crucial presumption of tectonic movement and developing processes. Tense-shearing and compresso-shearing structure accompanies two types of structural manners with striking and extending and contrcting action. A static coming from abundance of tense-shearing and compresso-shearing faults indicates that the two types of faults have specific spacial and profiling characters in sedimentary basins. What means that the former discerning of tense-shearing and compresso-shearing structures depending on positive flower and negative flower structures should be developed, and distinctly understanding tense-shearing and compresso-shearing structures is absolutely necessary condition to ascertain the tectonic evolution process of Bohai bay basin and its internal depressions.
