| 摘 要： | 白云金矿区总体构造为EW走向的线性褶皱构造,金矿体受EW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找金矿的最显著标志；深部矿化连续,具较好的找矿前景.

| Abstract: | The overall tectonic structure in the Baiyun gold mine is EW trending linear folded structure and the gold orebody is controlled by EW trending ductile to tenacity shear zone.The stratum of Liaohe supergroup is the source layer and the ores occur in third section of Dashiqiao group of Liaohe supergroup and in vein of Yanshanian period.The selection of the mineralization to certain rocks is not obvious and the deposit is characterized by evident tenacity shear zone while the obvious indicator for gold deposi... |
