摘　　要：彩霞山铅锌矿床位于塔里木板块北缘活动带卡瓦布拉克-星星峡中间地块,容矿地层为长城系星星峡群,含矿岩性为角砾状硅化粉砂岩、白云石大理岩.通过对矿体特征、稳定同位素、流体包裹体、微量元素等分析,认为彩霞山铅锌矿床成因类型为碎屑岩-碳酸盐岩容矿的后生层控-热液改造型矿床.通过与我国广东凡口铅锌矿床、新疆卡兰古铅锌矿床成因对比研究发现,彩霞山铅锌矿床与二者成因特征类似,具有MVT型矿床成因特征.The Caixia lead-zinc deposit is located in the middle blockof Kawabulake-Xingxingxia at northern active margin of the Talimu plate.The ore-bearing strata are the ChX.The rock of the lead-zinc deposit is mainly siliconed silt in general,others is contained dolomitized marble. Studying on the mine body characteristics,Stable isotope,flow inclusion, trace element and so on, the Caixia lead-zinc deposit forming type is epigenesis sedimentation-hydrothermal reconstruction which ored mineral clastic rock and carbonate.Though studying with Fangkou Guangdong and Kalangu lead-zinc deposit of Xinjiang, they have similar forming characteristics of MVT lead-zinc deposit.
