    摘要
  • 浙东南石平川钼矿区经过近数十年的地质勘查,累计查明钼资源量已达大型规模。为了更好地理解石平川钼矿区的控矿机制,为在老矿山外围确定新的找矿靶区提供理论依据,通过实地观测和分析矿区的层内构造、节理裂隙发育特征、石英细脉及微细脉穿切关系,利用区域构造解析法、节理统计分析法等,系统研究了石平川钼矿区的构造特征和控矿机制。钼矿床整体受到石平川火山穹窿和断裂构造的共同控制,均产于石平川火山穹隆范围内的断裂或层内构造带内,并严格受层内构造的控制,层内构造为辉钼矿脉的形成提供了运移通道和储矿空间,区域构造应力场及岩体冷凝收缩作用共同形成了矿区的层内构造。研究成果可为石平川钼矿区外围找矿靶区的筛选提供参考。
    After decades of geological exploration in Shipingchuan molybdenum mining area in the southeastern Zhejiang, the amount of molybdenum resources has reached a large scale. In order to better understand the ore control mechanism in Shipingchuan molybdenum mining area and provide theoretical basis for determining new prospecting targets around the old mine, the authors systematically observed and analyzed the characteristics of the intra layer structure, joint and fissure measurement statistics, quartz vein cutting relationship, and micro vein cutting relationship in the mining area. Regional structural analysis method and joint statistical analysis method were used to study the structural characteristics and ore control mechanism of Shipingchuan molybdenum mining area. The molybdenum deposit was generally controlled by Shipingchuan volcanic dome and structure,and it wholely occured within the faults and intra layer structure belts in the range of Shipingchuan volcanic dome. Besides, it was strictly controlled by the intra layer structure, which provides a migration pathway and storage space for the formation of molybdenite veins. The regional tectonic stress field and the condensation and contraction of the rock mass jointly formed the intra layer structure of the mining area. The study results could provide some references for prospecting targets screening in the peripheral areas of Shipingchuan molybdenum mining area.
