| 摘 要： | 新疆阿尔泰地区原生金矿的围岩蚀变较发育，且不同类型金矿床同时具有相同特征的围岩蚀变类型。多数金矿床的围岩蚀变具有分带性，从矿体或断裂面向两例呈对称分布。金矿化一般随绢英岩化、黄铁矿化等蚀变的增强而增强。围岩蚀变是成矿流体、围岩和构造活动共同作用的结果，也是金矿化的表现形式，而不同类型的围岩蚀变则是成矿流体在不同的物理化学条件下演化的产物，正是这种成矿流体沿破碎带活动，形成一个由高温到低温的蚀变类型组合及与之相应的围岩蚀变分带。

| Abstract: | The wall rock a1terations develop intensively in the primary gold deposits in AltayXinjiang. The same kind of wa1l rock alteration occurs in different types of gold deposits.They are characterized by zonation and distributed symmetrically on the both sides of thegold bodies. With the intensive phyllication and pyritization the gold mineralization in-creases gradually.The wall rock alteration is mainly resulted in coprocess of ore fluid. wall rock and tec-tonic activities. The ore fluids which originated from different physical and chemical condi-tions resulted in various alterations. It is the ore fluid that migrated a1ong the fracturezone to form a series of alteration from high to low temperature and caused alteration zona-tion for wall rock. |
