本文拟介绍早二叠世浅海沉积型海泡石矿床的地质情况,初步探讨其找矿条件和评价方法。不当之处,请批评指正。一区域地质在早古生代,萍(乡)乐(平)坳陷属降起地带,加里东运动期因诸深大断裂的强烈活动而陷落,开始了中泥盆世至早三叠世的沉积。印支运动后,坳陷逐渐解体,其上发育一些中新生代的陆相断陷盆地(图1)。海泡石矿床产在下二叠统小江边组内。小江边组遍及整个坳陷,但海泡石矿床(点)却局
This article intends to introduce the geological conditions of the Early Permian shallow-sea sedimentary sepiolite deposit and to explore its prospecting conditions and evaluation methods. Improper, please criticize correction. Geology of a region In the early Paleozoic, the Ping (Xiang) Le (Ping) depression belonged to the Lower Belt. During the Caledonian movement, the Cretaceous to Early Triassic sediments started to fall due to the intense activities of deep faults. . After the Indosinian movement, the depression gradually disintegrated and some Meso-Cenozoic continental rift basins were developed (Figure 1). The sepiolite deposit is produced in the Lower Permian basin. Small river edge group throughout the depression, but the sepiolite deposit (point) is the Council
