花垣县李梅超大型铅锌矿属层控矿床,赋存于寒武系下统清虚洞组下段第三、第四亚段(∈_1q~(1-3)～∈_1q~(1-4)厚层灰岩中,矿体呈似层状、顺层分布的透镜状和顺层分布的囊状,锌品位一般1.0～5.0%,多数在3%左右,矿石可选性好,回收率高。近年发现砾石胶结物型铅锌矿,提出了准同生成矿新思路。
The ultra-large lead-zinc deposit in Huayuan County is a strata-hosted ore deposit that occurs in the third and fourth sub-sections (∈_1q ~ (1-3) ~ ∈_1q ~ (1-4)) of the lower member of the Qing Xuelong Formation in the Lower Cambrian. In the thick limestone, the ore body is in the shape of a layer, the lenticular shape distributed along the layer and the cystic shape distributed along the layer. The grade of zinc is generally 1.0-5.0%, most of which is about 3%. The ore has good selectivity and high recovery rate. In recent years, found gravel cement type lead-zinc ore, put forward a new idea of quasi-formation of ore.
