摘　　要：锰矿是我国重要的战略紧缺资源。本文通过对云南省大平-鸣就地区矿产地质调查研究,首次发现在石炭系顺甸河组中赋存有工业锰矿。通过对矿区的岩相古地理、地质特征、地球化学特征的研究分析,表明该锰矿是在贫氧的环境下,形成于古陆边缘的浅海,属于台地边缘浅滩相的产物。该发现和研究为今后在该层位中寻找锰矿提供了重要线索和依据,为锰矿找矿工作提供了新方向。For the first time,this work has discovered industrial manganese ore in the Shundian River Formation of the Carboniferous in the Daping-Mingjiu area of Yunnan Province.Analysis of lithofacies,palaeogeography,geological characteristics and geochemical features of the survey area indicates that the manganese ore formed in a shallow sea at the edge of an ancient continent under an oxygen-lean condition,attributed to the sedimentary facies of the shallow sea shelf.This discovery and research provide important clues and evidence for searching manganese ore in this stratum in the future,and represent a new direction for manganese ore prospecting.
