摘要

摘要: 根据对祁连山、昆仑山、阿尔金山和柴达木周缘露头的野外地质调查和盆地地震反射剖面的解释, 分析了柴达木盆地及相邻造山带区域断裂系统及其对盆地演化的控制作用, 提出5个区域断裂系统对柴达木盆地的形成和发展演化起着重要控制作用: (1) 祁连山-柴达木盆地北缘断裂系统; (2) 东昆仑山-柴达木盆地南缘断裂系统; (3) 阿尔金走滑断裂系统; (4) 鄂拉山走滑断裂系统; (5) 甘森-小柴旦断裂系统.这些断裂系统控制了柴达木盆地的展布方向、盆地内次级断裂的形成和分布、沉积中心的迁移及油气聚集带的分布.

Abstract: The purpose of this paper is to analyze the regional fault systems of Qaidam basin and adjacent orogenic belts. Field investigations and seismic interpretations indicate that five regional fault systems occurred in the basin and adjacent mountain belts and that they control the development and evolution of the Qaidam basin. These fault systems are: (1) Qilianshan-northern marginal Qaidam fault systems; (2) East Kunlunshan-southern marginal Qaidam fault systems; (3) Altun strike-slip fault systems; (4) Elashan strike-slip fault systems; (5) Gansen-Xiaochaidan fault systems. It is indicated that the fault systems have great control over the orientation of the Qaidam basin, the formation and distribution of secondary faults within the basin, the migration of sedimentary center and the distribution of hydrocarbon accumulation belts.
