松辽盆地多边形断层的发现及其成因
DISCOVERY AND ORIGIN RESEARCHES OF THE POLYGONAL FAULTS IN SONGLIAO BASIN
摘要
Abstract
Polygonal fault ordinarily developed in deep water environment is a non-structured new fault, which is characterized by short fault throw, limited extended length and complex through-going. The similar studies of this kind of fault are only confined in deep sea basins in China. Recently, with the help of 3D seismic interpretation, the polygonal faults were discovered in Nenjiang Formation of Songliao Basin. It is the first discovery of polygonal fault in the eastern continental basins of China. By means of 3D seismic achievements, the characteristics of profile and plane of the faults are described. In the meantime, integrating with the previous research results, the forming origins of the faults are obtained in Nenjiang Formation in Songliao basin by the origin model interpretations of overpressure syneresis. And furthermore the significances for the discovery are discussed.关键词
