Abstract

The styles of structure systems are generally en echelon-distributed in plane in petroliferous basins in Eastern part and Central-Western part of China, which commonly resulted from shearing during tectonic evolution. Six typical features of shearing structure systems are summarized based on various styles of seismic structures in these regions by seismic profiles interpretation,such as extensional υ-type structural systems in Jiyang Depression and the λ-type fracturing structural systems in Jiyang Depression in Bohaiwan Basin during Tertiary pull-apart movement. The W-E-trending fracturing belts are common compressive but the NW-trending ones are right-lateral and NE-trending ones are left-lateral compresso-shearing structural systems in Tarim Basin under the effects of Honghe and Altun megafratures.
