【摘要】 Ｃ－俯冲带处于造山带和前陆盆地之间，形成于中国大陆拼结之后，因前陆盆地深层次构造失稳而向造山带俯冲挤压，导致造山带中、浅层次构造向前陆盆地方向道冲及浅表层次滑覆。Ｃ型俯冲属陆内俯冲性质，具有中国大陆地质构造演化特色，不仅在中国中西部造山带的形成及其前陆盆地的发展中有重要作用，而且对前陆盆地油气富集条件有重要影响。更多还原

【Abstract】 C-subduction zone, formed after the Chinese continent conjuction, occurs between orogenic belt and foreland basin, which has subducted and compressed into orogenic belts due to the unstablity of the deep-seated struc ture in foreland basin, resulting in the thrusting of the deep-seated structure into foreland basin and slipping of the shallow-seated structure in orogenic belt. C-subduction is with the nature of intracontinental subduction and has the characteristics of the tectonic evolution in the Chinese continent. It not only plays an important roles in formation and development of the orogenic belts and foreland basins in central-western China, but also has a significant effect on the hydrocarbon accumulations in foreland basins.更多还原
