摘要
Based on detailed geological work,the authors investigated three geological sections in Hexi and Dasanjie area within the northern part of Lanping Basin. The gypsum-bearing horizons are of the same attitude as the overlying and overlying carbonate layers. The rock associations of the horizons are different in different places, so that the stratigraphic sequences can’t be laterally correlated with each other. The salt-bearing horizons present some syn-sedimentation characteristics, but are different from the evaporate deposits formed by evaporation.
