摘要

摘要: 通过分析四川盆地东部垫江盐盆三叠纪嘉陵江成盐期构造演化及后期构造作用，结合大地电磁测深和地震资料解译等综合分析初步认为垫江盐盆三叠纪嘉陵江期，在整体海退的条件下，由于泸州—开江古隆起的逐步形成，在长寿合兴地区和垫江董家场地区形成有利于古卤水浓缩的次级凹陷。早白垩世末期川东褶皱带的形成虽然对三叠系含盐地层进行了改造，但次级凹陷位于向斜核部和褶皱倾末端，未受到风化剥蚀。同时，大地电磁测深和地震资料显示深部没有断裂构造穿过次级凹陷区域，初步证明具有较好的保存条件。

Abstract: Based on the analysis of the tectonic evolution and late-stage tectonics of the Dianjiang Salt Basin in the eastern Sichuan Basin, combined with magnetotelluric sounding method and seismic data interpretation, this paper holds that there are two sub-depressions in the Dianjiang Salt Basin. Both Hexing sub-depression and Dongjiachang sub-depression are advantageous to the concentration of ancient brine. Although the formation of the eastern Sichuan fold belt in the late Early Cretaceous reformed the Triassic salt-bearing strata, the secondary depression area was located at the syncline core and the end of the fold dip, and was not subjected to weathering. Meanwhile, the magnetotelluric sounding and seismic data showed that no fault structure existed in the two depression area, indicating the well preservation conditions.
