摘  要:托吐喀腊铜镍矿位于中亚造山带南部,准噶尔成矿带东北缘北塔山一带,含矿中-基性杂岩体呈岩枝状产出于NW-NE向断裂构造带上。岩性主要为角闪石岩、橄榄辉长岩、辉长岩、角闪辉长岩、闪长岩,具同源多阶段连续演化的特点。经初步评价,圈定铜镍矿体3个。矿体赋存于橄榄辉长岩-辉长岩中,可见星点状、浸染状、团斑状、块状等矿石构造。金属矿物主要为磁黄铁矿、黄铜矿、镍黄铁矿、黄铁矿,少量辉砷钴矿、铁闪锌矿。托吐喀腊铜镍矿床的发现拓展了准噶尔东北缘岩浆型铜镍矿的找矿空间。The Totukala copper-nickel deposit is located in the northern part of the Central Asian Orogenic Belt,in the northeastern margin of the Junggar metallogenic belt in the Beita Mountain area.On the belt,it is densely exposed within a range of 0.6 km2.The lithofacies are mainly hornblende,olivine gabbro,gabbro,hornblende gabbro and diorite,which have the characteristics of homologous and multi-stage continuous evolution.After preliminary evaluation,three coppernickel ore bodies were delineated.The ore bodies are hosted in olivine gabbro-gabbro,and ore structures such as star-like,disseminated,globular,and massive can be seen.The metallic minerals are mainly pyrrhotite,chalcopyrite,pyrite,pyrite,and a small amount of arsenite and sphalerite.The discovery of the Totukala copper-nickel deposit has expanded the prospecting space for magmatic copper-nickel deposits in the northeastern margin of the Junggar.
