补充资料：围岩蚀变
| 围岩蚀变 wall rock alteration 在热液成矿过程中，近矿围岩与热液发生化学反应而产生的一系列物质成分和构造、结构的变化。气化热液矿床中的普遍现象和重要特征，因其常与矿体伴生且其分布范围一般比矿体分布范围广，因而是一种重要的找矿标志。常见的围岩蚀变有：①夕卡岩化。多产在中酸性侵入岩与碳酸盐岩的接触带附近，常由石榴子石、辉石等矿物组成，有关矿产有铁、铜、钨、锡、钼等。②云英岩化。主要产于花岗岩类岩石中，由石英和白云母等组成，与钨、锡、钼、锂、铍等矿产有关。③绢云母化。一种广泛分布的热液蚀变，在中性和酸性火成岩及板岩等富铝岩石中最常见，常与黄铁矿和石英伴生，有关矿产有铜、钼、金、铅、锌等。④绿泥石化。产在多种岩石中，有关矿产有铜、铅、锌、金、银、锡等。⑤硅化。使围岩中石英或隐晶质SiO2显著增加的一种蚀变作用，分布很普遍，与铜、金、锑、汞、明矾石、重晶石等多种矿产伴生。 |
