| 中文摘要:池西铁铜矿床是近年来新发现的赋存在中天山前寒武纪基底卡瓦布拉克群 内的块状硫化物型矿床，具上铁下铜的分带性，在成因上可能与海相火山作用有关。已发现 的2个矿体呈层状、透镜状产出，产状与围岩地层一致。该矿床可能是中天山地区卡瓦布拉 克群内首次发现的块状硫化物型矿床，对今后在中天山乃至东天山地区寻找与海相火山作用 有关的块状硫化物型矿床（尤其是铁铜共生矿床）具有重要的参考意义。 |

| Abstract:The Chixi Fe_Cu deposit, located in Hami area, Xinjiang, is a new type deposit d iscovered in the central Tianshan Precambrian basement. This deposit is hosted within the metamorphosed submarine bimodal volcanic rocks of the Kawabulake Grou p (Pt2). Even BIF_type iron deposits (such as the Baishanquan iron deposit) an d SEDEX_type Pb_Zn_Ag deposits (such as the Yuxi silver deposit and the Xiqianlu zi Pb_Zn deposit), also hosted within the same metamorphosed strata, were discov ered many years ago, the Chixi Fe_Cu deposit is the first reported VHMS_type of Fe_Cu deposit hosted within the Kawabulake Group. The discovery of the Chixi Fe_ Cu deposit suggests a good potential for further prospecting of copper deposits in the central Tianshan region. |
