该矿床单独产光学萤石,为世所少见。矿床所在区域处于“康滇地轴”近北端之东翼,区内褶皱平缓,主要展布北东向和北北西向两组压性构造形迹,并显示后者受前者改造。区域地层为 Zα—K,累计厚度5900—8200米,其间缺失 D 和 C。各系地层之间均为平行不整合关系。区域西部有一较大的早震旦世花岗岩体呈北东向延伸,构成一背斜的核部。背斜南东翼为 Zα—P,倾向南东,倾角仅十余度。矿床即赋存于该翼寒武系与震旦系平行不
The deposit alone is made of optical fluorite, rare in the world. The area of the deposit lies in the east wing near the northern end of the “Kangdi-Dianxi” axis with gentle folds in the area, mainly exhibiting the compaction features of the two groups of NE and NW-NW pairs and shows that the latter is reformed by the former. The regional strata are Zα-K with a cumulative thickness of 5900-8200 meters, with D and C missing. All strata are parallel and unconformity. In the western part of the region, a larger Early Sinian granite body extends northeastward and forms a anticlinal core. The southwestern wing of the anticline is Zα-P, with a tendency to the south and a dip of only ten degrees. Deposits that occur in the wing Cambrian and Sinian parallel
