摘要
城口地区是我国锰矿资源重要产出基地之一。以城口地区大渡溪锰矿为研究对象,详细叙述了大渡溪锰矿床地质特征(包括赋矿层位、矿体特征、矿石结构构造、矿石成分以及矿体围岩组成等)。结合沉积学和岩相古地理的综合研究,认为该矿床为原生沉积、碳酸盐还原和生物作用三者结合的产物,并在此基础上总结了成矿模式,为下一步找矿工作提出了合理的建议。
Chengkou district is one of the most important production base of ore resources in China. The Daduxi manganese deposit in Chengkou county as the study object was taken, that descripted the geological features of the Daduxi manganese deposit in detail, incluing enriched ore layer, ore body characteristics, ore texture, ore struc- ture, ore composition, et al. Combined with the comprehensive study of sedimentology and lithofacies paleogeogra- phy, it believe that the deposit is the comprehensive effect of sedimentary, carbonate reduction and biological. Based on this, the metallogenic model was summed up, and put forward some reasonable suggestion for the next prospecting work.
