摘　　要：鄂西地区铅锌矿床的成因类型主要有两种:沉积型和热液型。沉积型铅锌矿主要形成于晚震旦世—寒武纪;热液型铅锌矿床主要形成于燕山中晚期,与区域性伸展构造事件密切相关,矿化主要集中于青峰强变形带、神农架断穹西部、黄陵断穹北部及咸丰背斜和长阳走马坪背斜等次级褶皱中。近年来的找矿勘查实践表明,区内铅锌成矿地质条件十分有利,找矿前景良好。Pb-Zn deposits in the western Hubei Province were mainly formed through sedimentation and hydrothermal deposition. Sedimentary type deposits usually formed during late Sinian to Cambrian period. Hydrothermal type deposits are mainly related to middle-late Yanshanian regional extension, and mineralization happened mainly in Qingfeng competent deformation zone, western Shennongjia faulted dome, northern Huangling faulted dome, secondary Xianfeng and Zoumaping anticline. Recent explorations show that there are very excellent geological conditions and prospecting potential in the studied region.
