| 摘 要： | 云岭金矿位于安徽省泾县西部,地处扬子陆块下扬子地块南缘褶断带,金成因类型以残坡积型金为主。文章通过对其金成矿地质特征进行分析研究认为,金矿化受泥盆系五通组砂岩、石炭系黄龙组灰岩、二叠系栖霞组灰岩、北东向断裂构造、云岭花岗闪长岩体以及古地貌控制;金矿化的形成过程:早期岩浆热液形成的含金硫铁矿体受后期构造挤压破碎作用,抬升露出地表后,经氧化、风化及后期堆积作用,最终形成现今的残坡积型金矿体。

| Abstract: | The Yunling gold deposit lies in western part of Jing County, on the southern fringe folding belt of the lower Yangtze massif of the Yangtze landmass, and is dominated by residual gold mineralization in origin. Based on analysis of ore-forming geological features, this paper found that gold mineralization is controlled by Devonian Wutong Formation sandstone, Carbonaceous Huanglong Formation limestone, Permian Qixia Formation limestone, NE-trending faulting structure, Yunling granodiorite intrusion and ancient landform. The gold mineralization process is like this： early magmatic hydrothermal fluid formed gold-bearing pyritic ore body, which was structurally compressed, broken and uplifted to the surface, and then subjected to oxidization, weathering and accumulation, and finally turned into residual gold ore deposit as what we see today. |
