依舒地堑方正断陷断层组合及构造样式
FAULT ASSEMBLAGE AND STRUCTURAL MODE OF FANGZHENG RIFT OF YISHU GRABEN
摘要
Abstract
According to the newly acquired 3D seismic data in the Fangzheng Rift, three kinds of fault types including tensional or transtensional, compressional or compressional-shear and stike-slip faults are well developed, thus eight types of fault combinations such as horst, graben, step, Y-shaped, imbricated, hedge, positive flower and negative flower shapes are formed. And furthermore so do four kinds of structural styles; stretched, compressional, strike-slip and reverse. On the basis of the above, the genetic mechanism and distribution characteristics of the fault assemblage and structure styles are analyzed. These achievements have laid the foundations for the further studies of tectonic framework, tectonic evolution and the prediction of the types and distributions of the favorable oil-bearing structures in the rift.关键词
