| 摘 要： | 沅陵一带的黄铁、铅锌矿床,赋存于上震旦统远硅质建造白云岩层位中。矿质主要来自矿层顶板硅质页岩建造,受层、相、位联合控制.矿石物质组分简单,沉积组构保存较好,又经受轻微的后期改造富集。为华南前寒武系中不多的沉积改造型黄铁、铅锌矿床.

| Abstract: | Pyrite and lead-zine ore-deposits in Yuanling existing in dolomitite stratum belong to tele-siliceous formation of upper Sinian series. The ore minerals came from upper-plate of ore layere that is the silicious shale formation. There are three faciors which contril forming of this ore-deposits, they are stratum, lithofaces, horizon. The composition of the ore minerals is simple. It was slighlly reworked and concentrated, the depositional facbric is preserved very well. It is a rare type of reformed sedimentary pyrite and lead-zinc ore-deposits of Precambrian in South China. |
