摘　　要：汤原断陷位于我国东北依兰-伊通地堑北部,为新生代断陷盆地。汤原断陷早期经历拉张和断陷,后期经历挤压和抬升,在早期断陷基础上,后期发生构造反转,形成东西分带和南北分段的构造格局。汤原断陷主要发育两个反转构造带,分别为中部反转凸起带和东南缘挤压走滑构造带,分析反转构造的形成及特征,总结反转构造有利成藏条件,认为吉祥屯-龙王庙反转构造带以及东南缘挤压走滑带具有较好的勘探潜力,这两个反转构造带为汤原断陷有利勘探区带。The Tangyuan Fault-depression is in the north of Yilan-Yitong Graben in the northeast of China,and is a Cenozoic faulted basin.The Tangyuan Fault-depression experienced tension and fault depression in the early stage,and compression and uplift in the later stage.Based on the early fault depression,the tectonic inversion occurred in the later stage,forming a structural pattern of east-west zonation and north-south segmentation.The Tangyuan Fault-depression mainly developed two reversal structural belts,namely the central reversal bulge belt and the extrusion strike-slip structural belt in the southeast margin.The formation and characteristics of the reversal structure are analyzed,and the favorable accumulation conditions of the reversal structure are summarized.It is considered that the Jixiangtun-Longwangmiao reversal structure belt and the compression strike-slip belt on the southeast margin have good exploration potential.These two reversal structure belts are favorable exploration zones in the Tangyuan Fault-depression.
