贵州省纳雍县偏坡寨矿区钼多金属矿地质特征及找矿前景

Geological Characteristics and Prospecting Potential of Molybdenum Polymetallic Deposits in Pianpozhai Mining Area in Nayong County of Guizhou Province

摘要:

贵州省钼矿资源丰富，钼矿资源的勘查和开发利用具有重要的经济和战略意义。贵州钼矿主要产出层位为下寒武统牛蹄塘组底部“磷块岩(上磷层)之上的金属层”，通过在纳雍县偏坡寨矿区进行钼矿详查工作，基本查明矿区地层层序、分布特征，主要含矿层的性质、产状，控矿构造因素及矿化富集的条件，成矿后构造的破坏影响程度，含矿层的沉积环境特征。该区钼矿层形态、规模、产状、分布严格受牛蹄塘组控制，为在广海静水或斜坡相缺氧还原条件下沉积形成的矿床，受时代控制、地层层位控制、岩相古地理控制明显，具有较大的资源潜力和良好的找矿前景，为进一步寻找钼矿提供借鉴。

Abstract:

There are rich molybdenum resources in Guizhou province. The exploration, development and utilization of molybdenum resources have important economic and strategic significance. Through detailed investigation of molybdenum deposits in Pianpozhai mining area in Nayong county, stratigraphic sequences and distribution characteristics The property and occurrence of main orebearing strata, orecontrolling structural factors and mineralization condition, the degree of structural damage after mineralization and the sedimentary environment characteristics of ore bearing strata have been basically identified. The shape, scale, occurrence and distribution of molybdenum deposits in this area are strictly controlled by niuditang formation. The deposit is formed under the condition of anoxic reduction of Guanghai still water or slope facies. They are obviously controlled by age, stratigraphic horizon and lithofacies paleogeography. There are great resource potential and good prospecting prospects, which can provide references for further molybdenum exploration.
