| 摘 要： | 阿希金矿产于下石炭统大哈拉军山组,第五岩性段构成的古火山机构西南缘。矿体产出形态及空间分布,严格受近南北向弧形张扭性断裂控制。主矿体呈厚大似板状体,以南北两个富集中心向NE50°倾角侧伏。矿石以石英脉型为主,其次为蚀变岩型。围岩为英安岩和角砾熔岩。属中一低温火山期后热液型金矿床。

| Abstract: | The Haxi gold deposit occures in the southwestern margin of the paleovolcanic structure formed by the fifth member of the lower Carboniferous. The morphology and spacial distribution of the ore body are strictly controlled by the N-S arc-shaped tensional and torsional fractures . The main ore body, in a large thick tabular shape, is dipping at the angle of 50'c to the northwest from two (south and north) concentration centers. The ores are mainly of quartz vein type followed by alteration type. The country rocks are dacite and breciated lava. So the Haxi gold deposit is believed to be of postvolcanic hydrothermal type of low to intermediate-temperature. |
