毛坪铅锌矿床地层-岩性-岩相古地理控矿特征
|
摘要
毛坪铅锌矿为一大型铅锌矿,其矿体赋存于泥盆系、石炭系地层内。从矿区地层、岩性、岩相古地理3个方面的控矿特征,进行深入研究与分析,结果表明:(1)毛坪铅锌矿床是在地层、岩性、岩相古地理的特殊组合下形成的大型铅锌矿床;(2)地层控矿表现为多层位含矿、主矿体集中、有沉积韵律现象、矿体受地层厚度影响明显等特征;(3)地层岩性影响矿体成矿规模;(4)岩相古地理为铅锌矿的富集提供了较好成矿的环境。研究成果可为下一步找矿提供指导。
Maoping Lead-Zinc Mine is a large lead-zinc mine and the ore body was deposited in the strata of the Devonian System and Carboniferous System.A deep study and analysis was conducted on the ore control features from three aspects of the strata,lithology and lithofacies paleogeography in the mining area.The results showed that(1)the lead-zinc deposit of Maoping Mine is a large lead-zinc deposit formed under the special combination of the strata,lithology and lithofacies paleogeography.(2)The ore control of the strata had the multi layers with ore,the main ore body concentrated,sedimentary rhythm phenomenon,the ore body affected by the strata thickness obviously and other features.(3)The strata lithology was affected to the formation scale of the ore body.(4) The lithofacies paleogeography could provide good formation environment of the lead-zinc enrichment in the mine.The study results could provide the guidance to the further ore exploration.
