摘要: 巴彦浩特盆地是近年来开始加强油气勘探的重要盆地.它位于阿拉善地块、鄂尔多斯地块、河西走廊过渡带三大构造单元交汇处,是经过不同时期、多次构造运动改造而形成的复合叠加型盆地.它的形成与所处的特定大地构造位置密切相关.该文从区域构造特征入手,深入分析和总结了巴彦浩特盆地在不同地质历史时期的盆地原型及其演化特征.作者认为巴彦浩特盆地及其周缘地区经历了早、中元古代的秦、祁、贺三叉裂谷演化阶段,晚元古-寒武、奥陶纪的坳拉槽演化阶段,志留、泥盆纪的前陆盆地演化阶段,石炭、二叠纪的复合盆地演化阶段,以及中、新生代的断陷盆地演化阶段.Abstract: The Bayanhaote Basin is an important basin to which the exploration of hydrocarbon is strengthened in recent years.It is located in the juncture of three tectonic units,that is,the Alashan Massif,the Ordos Massif and the Hexi Corridor in termediate zone.It is a compound and superimposed basin formed from different periods and many times of tectonic movement reformation.Its formation is closely related to the specific geotectonic location it lies.Starting with regional tectonic characteristics,the prototypes of the Bayanhaote Basin and their evolutionary characteristics in differnt geological historical periods are analysed and summarized thoroughly.The authors considered that the Bayanhaote Basin and its peripheral regions experienced the evolutionary stages of the Early-Middle Proterozoic Qin-Qi-He Trigeminal Rift,the Late Proterozoic-Cambrian Ordovician Aulacogen,the Silurian Devonian Foreland Basin,the Carboniferous-Permian Compound Basin and the Mesozoic-Cenozoic Fault Basin.
