| 摘 要： | 白山梁铜矿位于河西走廊西北部金塔县北山,属风化剥蚀、低山丘陵区。矿床大地构造位置属哈萨克斯坦板块马鬃山中间地块东南边缘,音凹峡-白山堂伸展断陷盆地内白山堂隆起带的南缘。矿区内网脉状裂隙和节理带发育为含矿热液体的上侵定位提供有利的空间条件。矿体的分布主要受东西向断裂构造控制,主要矿体均呈东西向或近东西向展布,层间断裂破碎带是主要的找矿标志。

Orebody Features and Oregenesis Analysis of Jinta County Baishanliang Copper Deposit |
| |
| Abstract: | Baishanliang copper mine is located in the Beishan of the Jinta county in the northwestern Hexi corridor, belongs to weathering erosion, low hilly land.The deposit’ s geotectonic position belongs to southeast edge of Mazong mountain mas-sif of the Kazakhstan plate, in southern margin of BaiShanTang uplift belt within the Yinaoxia gorge-Baishantang stretching rift basin.The net vein fissure and joint development in the mining area provide favorable space conditions for the upward assault and positioning of the ore-bearing hydrothermal liquid.The orebody is mainly controlled by the east-west fracture structure, the distribution of ore bodies is primarily east-west or nearly east-west distribution, interlayer fractured zone is the main prospecting marks. |
