摘　　要：布尔克斯岱金矿床位于新疆准噶尔西北缘的萨吾尔山东部,是准噶尔地区最典型的浅成岩-构造蚀变岩型金矿床之一。它既与断裂构造带有关,同时也与浅成岩脉关系密切,受浅成岩脉和断裂构造的双重控制,因而区别于一般的构造蚀变岩型金矿床。其突出特点是:最好的矿化部位通常在浅成岩脉与沉积岩层之间的接触带附近,在浅成岩脉的膨胀部位,通常存在较宽大的富矿体。下石炭统黑山头组的含炭质泥质碎屑岩建造,也是其重要的含金建造。The Buerkesidai gold deposit is located in the eastern Sawuershan, the north-western margin of the Zhunge'er Basin, Xinjiang, and is one of the most typical supergene-structural altered-rock type gold deposits in the Zhunge'er area. The metallogenesis was associated with the fracture deformation and the supergene magma invasion. The gold ore bodies were controlled by the fault zones and the supergene veins. It is different from the normal structural altered-rock type gold deposit. The main characteristics are the best mineralized parts commonly existed near the contacting zones between the fractured zone and the supergene vein, and the bigger rich ore bodies are generally located near the expanded part of the supergene vein. The important gold-bearing formation is the carbonaceous muddy clastic rocks of the Lower Carboniferous Heishantou formation.
