本文阐述一个呈钟乳状、腊光褐铁矿状岩溶型菱锌矿矿床的地质特征。它位于区域性地壳隆起的背斜倾伏端,晚震旦世碳酸盐岩分布地区。储矿岩溶体属陡山沱组上段,夹于不透水层之间的碎屑状碳酸盐岩中;在构造上受次级背斜控制;成矿物质来源于陡山组上段的铅锌矿、银钒矿和灯影组底部铅锌矿层。地表水通过断裂、层间裂隙渗入矿源层。在溶蚀,水解等作用下形成菱锌矿矿床。
This article describes the geologic features of a bell-shaped, waxy limonitic karst type calamine deposit. It is located in the regional crust uplift anticline dip end, late Sinian carbonate distribution area. The ore-storing rocks are in the upper part of Doushantuo Formation and clamped in clastic carbonate rocks between impermeable layers; controlled by secondary anticlines in structure; the ore-forming materials are derived from the lead-zinc Mine, silver and vanadium ore and light shadow at the bottom of the lead-zinc deposits. Surface water through the fracture, interbed cracks into the source layer. In dissolution, hydrolysis and other functions under the formation of calamine deposits.
