| 摘 要： | 斑岩型金矿包括伴生、共生和独立斑岩型３个亚型。峪耳崖和牛心山独立斑岩型金矿有诸多相似之处。二者都与浅成小岩株、磁铁矿系列花岗岩有关；矿上单脉型和细网脉浸染型两种矿石组成。单脉型矿体以线性蚀变为特征，细网脉浸染型矿体则赋存在面型石英－绢云母化蚀变带内。峪耳崖和牛心山金矿是我国极具代表性的贫铜独立斑岩型金矿，在冀东、辽西和内蒙古境内有良好的找矿前景。

| Abstract: | Porphyry gold deposits include three subtypes: paragenetic type, associated type and independent porphyry type. There are many similarities between Yuerya and Niuxinshan independent porphyry deposits. Both are related to the hypabyssal stock and the magnetite series granites. The orebodies are divided into two styles: single vein and fine network disseminated ores. Single vein orebody is characterized by line alteration. Network disseminated orebody is located within the banded quartz sericitized alteration belts. The two deposits are typical representative of Cu dilution independent porphyry gold deposits in China. There is a good exploration prospect in eastern Hebei, western Liaoning and Inner Mongolia. |
