摘要
白云金矿区总体构造为东西走向的线性褶皱构造,金矿体受东西向展布的脆-韧性剪切带控制.辽河群地层是矿源层,矿体赋存于辽河群大石桥组三段及盖县组地层和燕山期的岩脉中,矿化对岩石无明显选择性,矿床具有明显的韧性剪切带特征.硅、钾蚀变带加上黄铁矿化是寻找金矿的最显著标志.深部矿化连续,具较好的找矿前景.提出了深部勘探工作方向和建议.
The Baiyun gold deposit in Liaoning Province is tectonically located in the conjunction of Dashiqiao-Caohekou fault depression and Yingkou-Kuandian fault uplift,in the middle of Eastern Liaoning rift,on the north margin of North China plate.The general structure in the orefield is the E-W-trending linear fold.The gold orebodies are controlled by the E-W-running brittle-ductile shear zone.The Liaohe group behaves as source bed.The gold ore occurs in the strata of Gaixian formation and the third member of Dashiqiao formation and the Yanshanian dykes.The mineralization has no obvious choiceness to rocks.The deposit is characterized by ductile shear zone.Pyritization in the silicic and potassic alteration belt is the notable indicator for gold prospecting.The metallogenesis in the deep is continuous,with great potential.
