摘要: 塔北隆起张性构造带分布于隆起轴部的轮台断隆上,主要为早期断裂受喜马拉雅运动早期的左旋扭动在浅层派生的北西-南东向张性构造。断裂在平面上呈左行雁列展布,在剖面上为小型地堑组合,部分断裂向深部与先存断裂联合形成负反转构造。与断裂相伴的褶皱构造沿断裂走向分布,且受断裂活动控制。塔北隆起张性构造带位于极有利的构造部位,具有良,好的油气远景。

Abstract: Tabei uplift tensional tectonics belt distributed in Luntai fault-uplift at its axis, mostly formed in early period of Himalayan event, controlled by the left-lateral couple of force, resulted from NW-SE striking local tensile stress field caused by sinistral torsion of the pre-existing fault in early period of Himalayan orogeny. Faults appear in a left-lateral echelon arrangement in plane and as small-sized graben combination in section. The deeper part of faults formed negative inverted structure along with the pre-existing fault. Fold structure associated with the fault distributed along fault strike, controlled by faulting. Tabei uplift tensional tectonics belt is. expected to have satisfactory oil and gas prospect due to its favorable structural position.
