| 摘 要： | 简要叙述了黔西北地区铅锌矿的地质特征，从断陷盆地、构造、地层岩性、矿化富集、热液活动、物化探异常几个方面论述了它的成矿规律。认为水城断陷盆地控制了区内铅锌矿床（点）的分布区域；NW向构造带控制铅锌矿床（点）的集中产出，其内之断层和层间构造带直接赋存铅锌矿床；石炭－二叠系地层的白云岩、白云质灰岩、灰岩是含矿的有利岩性；多期次的构造岩浆活动与铅锌矿成矿有关；物化探异常均沿NW向构造展布，异常浓集中心往往与矿床（体）吻合。初步建立了该区铅锌矿找矿模式雏形。

| Abstract: | This paper summarizes the geology of the Pb-Zn deposits in the areas of southwest Guizhou, and discusses its ore-forming regulation in view of fault-subsidence basin, structure, stratum lithology, mineralized concentration, thermal activity and abnormal of physical chemical exploration. In the writer's opinion, the Shuicheng fault-subsidence basin governs the distributed zones of the Pb-Zn deposit or ore points in the areas; the structural belts with NW strikes control the concentrated yields of the Pb-Zn deposits or ore points, its interior faults and interstratified structural belts directly preserves the Pb-Zn orebodies; the dolomites in the Carboniferous-Permian strata, dolomitic limestone and limestone are good lithology of ore-bearing; multi-stage structural magmatic movement is correlated to the mineralization of the Pb-Zn deposits; the abnormal of physical chemical exploration distributed along the NW strike, the anomalous concentrated core usually is coincided with the deposits or orebodies. The prospecting model for the Pb-Zn deposits in the areas is established initially. |
