白云金矿集区位于辽宁凤城白云—小佟家堡子金矿国家级规划重点勘查区内，沿尖山子断裂由北向南划分为3个矿带，矿带由北向南走向由近东西向转为近北西西向，矿床分布与辽河群大石桥岩组三段和盖县岩组地层分布具有一定的成矿专属性。在该矿集区深边部已取得一定找矿突破。其中，位于白云—冯家—石棚沟北金矿带的鸡爪金矿床是近年来新发现的金矿床。矿区出露地层主要为古元古界辽河群大石桥岩组，运用追索成矿构造带法，探矿工程揭露9条矿体，金平均品位6.41 g/t，银平均品位29.83 g/t。矿体主要赋存于北东东向—近东西向矿化蚀变带，倾向南或西南，倾角10°～70°。矿区东部矿体类型为蚀变岩型，西部为石英脉型。围岩蚀变以钾长石化和硅化为主。金和银等多金属化探异常和低阻高极化物探异常是重要的找矿标志。矿床成因类型为变质-热液型。

Baiyun gold ore concentration area is located in Baiyun-Xiaotongjiapuzi National Key Exploration Area for gold mines in Fengcheng,Liaoning.The district is pided into 3 mineralized belts along Jianshanzi Fault,transitioning from a near EW to a near NWW trend from north to south.The distribution of gold deposits has certain metallogenic specificity with the stratigraphic distribution of the Dashiqiao Formation and the Gaixian Formation of the Liaohe Group.Certain exploration breakthroughs have been made in the deep and peripheral sections of the district,with Jizhua Gold Deposit,located in the Baiyun-Fengjia-Shipenggoubei Gold Belt,being a notable recent discovery.The outcropping strata mainly consist of the Paleoproterozoic Dashiqiao Formation of the Liaohe Group.Using a metallogenic structural belt tracing approach,9 ore bodies were identified through exploration,with average grades of 6.41 g/t gold and 29.83 g/t silver.The ore body occurs predominantly within NEE-nearly EW trending mineralized alteration zones,dipping south or southwest at angles of 10° to 70°.Orebody types are alteration rock-type in the eastern part of the district,while orebody types are quartz vein-type in the western part.Alteration is dominated by K-feldspar and silicic processes.Geochemical anomalies for multiple metals like gold and silver,along with geophysical low-resistivity and high-polarization anomalies,are key prospecting indicators.The deposit is classified as metamorphic-hydrothermal in genesis.
