【摘要】 柴达木盆地是一个多成因的叠合含油气盆地,不同学者对其在不同演化阶段的成因特征和形成机制认识有较大差异;在分析、归纳、总结了4种有代表性的基本观点的基础上,结合区域构造演化、沉积发育、构造发育史恢复、地震反射特征,提出柴达木盆地形成与演化经历了早中侏罗世断陷盆地、晚侏罗世—白垩纪挤压挠曲盆地、古近纪挤压坳陷盆地和新近纪—第四纪前陆盆地共4个阶段的新观点,统一了对柴达木盆地成因类型及其形成机制的认识,对深化盆地地质认识、正确评估盆地资源有重要意义。更多还原

【Abstract】 The Qaidam Basin is a petroliferous basin with multiple genetic types.There are many different view points about its genetic characteristics and mechanisms during different evolution stages.Based on 4 main view points,combined with regional tectonic evolution,sedimentary generation,tectonic history restoration and seismic reflection characteristics,it is concluded in this paper that,the Qaidam Basin has experienced 4 stages: rift-subsidence basin from early to middle Jurassic,compression-inflection basin from late Jurassic to Cretaceous,compression-depression basin during early Tertiary and foreland basin from late Tertiary to Quaternary.This new opinion unifies knowledge about basin genetic types and mechanisms of the Qaidam Basin.It is very important for further research of basin geology and resource evaluation.更多还原
