摘要
通过对豫西南地区中元古界官道口群、上元古界栾川群与铅锌银有关的沉积建造中元素含量分布、表生富集特征及综合地球化学异常特征的研究,认为官道口群、栾川群是铅锌银矿的矿源层,并指出龙家园组、南泥湖组、煤窑沟组是寻找与官道口群碳酸盐岩和栾川群碎屑岩-碳酸盐岩沉积建造有关的层控铅锌银矿床的有利层位。
Based on a study of elements distributed in Pb-, Zn-, Ag-related sedimentary formations within Mesoproterozoic Guandaokou Group and Upper Proterozoic Luanchuan Group in southwestern Hanan area, the supergene enrichment of these elements, and the distribution characteristics of integrated geochemical anomalies, the authors bold that Guandaokou Group and Luanchuan Group are Pb, Zn, Ag source beds, and that Longjiayuan Formation, Nannihu Formation and Meiyaogou Formation seem to be favorable horizons in search for stratabound Pb, Zn, Ag deposits related to such sedimentary formations as carbonate rocks of Guandaokou Group and clastic rocks-carbonate rocks of Luanchuan Group.
