摘要
在综合分析区域地质、构造等资料的基础上,结合中国西北地区中生代构造背景的研究成果,证实了焉耆盆地早侏罗世处于弱伸展环境中,同时结合区内地震剖面特征以及热史的研究证实焉耆盆地侏罗系盆地原型为拉张背景下的断陷盆地。
On the basis of the integrated analysis of the regional geology,tectonic and deposition data,combined with the tectonic setting of Northwest China in the Mesozoic,this paper proves that in the Early Middle Jurassic,the Northwest China formd in a comparatively weak outspread environments.At the same time,combined with the study of seismic profile characteristics and thermal history,it is confirmed that the prototype of the Jurassic basin in Yanqi Basin is a rifted basin under tension background.
