| 摘 要： | 铝土矿床（点），位于南天山石炭纪被动大陆边缘，其中阿依里河是铝土矿成矿中心，区域上矿体沿地层走向在北东、南西地区均有稳定的延伸。以阿依里河铝土矿矿床为例，阐述了新疆乌什北山一带铝土矿成矿地质条件、含矿层位、矿床地质特征。工业铝土矿体主要产在中石炭统灰岩内的3个侵蚀面上，矿体以似层状、透镜状为主，其形态及规模受侵蚀面及古地形的控制。笔者分析了铝土矿矿床成因类型、矿石类型，总结了矿区的成矿规律和铝土矿找矿标志，乌什北山一带有形成大中型铝土矿成矿的地质条件，具有寻找大型铝土矿的找矿远景和潜力，认为滚滚铁列克至英阿特一带中石炭统分布的狭长地带是重要的找矿靶区。

| Abstract: | Several bauxite deposits have been discovered in north area of Wushi, Xinjiang, recently. These bauxite deposits are situated in the edge of passive continent margin of Carboniferous system in south Tianshan where the Ayili River is the bauxite-enriched center, with the ore body steadily extending in NE and SW directions in this region. On the basis of Ayili River ore deposits, we expound the ore-forming geological conditions, bauxite-bearing stratum, and deposit character in this area. The commercial bauxite deposits are formed in three eroded surfaces of middle carboniferous limestone, dominated by bedded and lenticular ore bodies, whose pattern and size are controlled by the eroded surfaces and ancient landform. In addition, we analyze the genesis type and ore type, and summarize the ore-forming rules and prospecting indicators for the bauxite deposit. Our study shows that the north Wushi area possesses the geological condition for forming large-sized or moderately-sized bauxite deposit and so has a potential of prospecting large-sized bauxite deposit. In addition, the Gonggongtielieke-Yingate zone in nor the Wushi area where the middle carboniferous limestone is distributed is an target area for bauxite deposit. |
