| 摘 要： | 以北山地区两个斑岩铜矿床的含矿岩体为例，系统研究了火山岩－斑岩体系的岩石学及地球化学特征和产出构造环境。发现斑岩铜矿区皆发育有钾质、钾钠质、钠质三种类型的中酸性岩类岩石组合，矿区岩石与外围及区域岩石相比，在稀土配分和微量元素特征上有很大差别。总结出以白山堂流纹斑岩为代表的酸性斑岩和以公婆泉英安斑岩－花岗闪长斑岩为代表的中酸性斑岩的含矿判别标志。

| Abstract: | Ore-bearing porphyries of the two porphyry copper deposits is examplified to make a systematic study on the petrology,lithochemistry and geochemistry of porphyry system as well as its tectonic setting. In ore districts, three typies of rock association such as K, K-Na and Na have been identified in these volcanic rocks, especially acid and intermediate to acid rocks.The rocks of ore district, periphery and region have differences in characteristics of REE and trace elements. The diagnostic marks of acid ore-bearing porphyry in the Baishantang deposit and intermediate to acid ones in the Gongpoquan deposit are summarized |
