摘要: 新疆小热泉子铜矿区总体为一NW-SE走向的不协调短轴复背斜,后期有SN向次级褶皱叠加。区内NW向断裂发育,均为EW向大断裂之分支断裂,规模小,无推覆性质,主要矿床(Ⅰ号矿床)呈较为典型的立交桥式双层成矿模式。矿床成因类型为中温热液充填-交代型铜(锌)矿床。

Abstract: The major structure in the mine district is NW-SE-trending disharmonic brachy anticlinorium superimposed by later N-S-trending second-order fold.NW trending minor faults as branch faults of E-W-trending major faults are well developed.The main ore deposit (No.1) is characterized by a duplex mineralization.The deposit is considered as a mesothermal filling-replacement copper deposit.
