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。
雲嶺金礦位于安徽省涇縣西部，地處颺子陸塊下颺子地塊南緣褶斷帶，金成因類型以殘坡積型金為主。文章通過對其金成礦地質特徵進行分析研究認為，金礦化受泥盆繫五通組砂巖、石炭繫黃龍組灰巖、二疊繫棲霞組灰巖、北東嚮斷裂構造、雲嶺花崗閃長巖體以及古地貌控製；金礦化的形成過程：早期巖漿熱液形成的含金硫鐵礦體受後期構造擠壓破碎作用，抬升露齣地錶後，經氧化、風化及後期堆積作用，最終形成現今的殘坡積型金礦體。

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.
