The research area is located in northern depositional depression of Heibei depression,which is part of the Dalangtan depression.Located in the northern part of Hongsanan-1 and the steep hill,it is divided into two irregularly shaped late Pleistocene depositional depressions in the south and north with small sedimentary thickness.In this paper,the stratigraphic,including tectonic and deposit characteristics are all analyzed in detail.The long-term evaluation of salt mineral resources is of great guiding significance to the exploration of geology and mineral resources in the future.%研究区位于黑北凹地的北部沉积凹地,黑北凹地属大浪滩凹陷区的一部分,位于其北部红三旱一号及尖顶山、黑梁子、长尾梁构造间,尖北隐伏构造将其分割为南、北两条不规则形的晚更新世沉积凹地,沉积厚度小.对地层、构造、矿床特征进行详细分析,进而对盐类矿产资源远景评价,对研究区以后的地质矿产勘查工作具有十分重要的指导意义.
