新疆乌伦布拉克铜矿床直接产于一套由浅成—超浅成或次火山侵入的黑云母闪长岩、石英闪长岩、斜长花岗岩和英安玢岩质隐爆角砾岩构成的花岗质潜火山杂岩中。含矿岩石属钙碱系列,具有低Si、低碱,富Na贫K,过铝质-偏铝质,轻稀土富集、重稀土亏损、铕弱负异常,强不相容元素相对富集,Nb和Ti强烈亏损,Rb、Th、K、Tb相对富集等岩石地球化学特征,成因上属造山壳幔同熔型花岗岩类,成岩时代属华力西中晚期。矿化作用以全岩式铜矿化为特征;矿石构造为浸染状、细脉浸染状、网脉状及团块状;矿石中发育交代结构和固溶体分离结构。蚀变以钾化、绢英岩化、硅化、青盘岩化广泛发育为特征。石英-钾长石-黄铜矿脉中石英包裹体水δD为-102×10-3,δ18O为8.4×10-3,均一温度为119～190℃。矿床成因属典型的含矿化隐爆角砾岩筒的斑岩型铜矿床。
The Ulun Bulak copper deposit in Xinjiang is directly produced from a suite of biotite diorite, quartz diorite, plagiogranite and quartzite cryptoexplosive breccia invaded by supergene or supervolcanic volcano In the granitic subvolcanic complex. The ore-bearing rocks belong to the series of calc-alkaline rocks with low Si, low alkali, Na-poor K, peraluminous-partially aluminous, light rare earth enrichment, heavy rare earth loss, weakly europium negative anomaly and relatively strong strong incompatible elements , Nb and Ti are strongly depleted, and Rb, Th, K and Tb are relatively enriched in lithogenic geochemistry. The genesis was from the orogenic crust and mantle-melting granitoids, and the diagenetic period belonged to the middle and late stages of the Variscan period. The mineralization is characterized by whole-rock copper mineralization. The ore structure is disseminated, veinlet disseminated, reticulated and massive. Ore structures are developed and the solid solution separation structure is developed. Alteration is characterized by the widespread development of potash, sericite petrification, silicification, and green-plate petrography. Quartz-K-feldspar - chalcopyrite vein quartz inclusions water δD of -102 × 10-3, δ18O of 8.4 × 10-3, uniform temperature of 119 ~ 190 ℃. The genesis of the deposit belongs to the typical porphyry copper deposit containing the mineralized crypto-explosive breccia tube.
