摘　　要：火烧云铅锌矿为层间溶蚀-构造带控矿,为早侏罗世SEDEX型Pb-Zn矿床新型;多宝山铅锌矿表现断裂控制后生产成矿作用特征,为MVT型Pb-Zn矿床;甜水海铅锌矿为残坡积成矿特征,裂陷盆地边缘产出的MVT型Pb-Zn矿床。笔者认为神仙湾裂陷盆地的南缘为寻找SEDEX型Pb-Zn矿床的有利环境,而盆地的北缘是寻找MVT型铅锌矿床的有利环境。Huoshaoyun Pb Zn deposit is a new type of SEDEX Pb Zn deposit in early Jurassic,which is controlled by interlayer dissolution structural belt;The Duobaoshan Pb Zn deposit is a MVT type Pb Zn deposit,which is characterized by post fault controlled mineralization;The Tianshuihai Pb Zn deposit is a MVT Pb Zn deposit in the margin of rift basin.The author thinks that the southern margin of shenxianwan rift basin is favorable environment for searching SEDEX type Pb Zn deposit,while the northern margin of shenxianwan rift basin is favorable environment for searching MVT type Pb Zn deposit.
