| 摘 要： | 本文重点论述了甘孜－理塘断裂带北段嘎拉金矿床含金剪切带围岩蚀变类型、阶段，讨论了构造－蚀变岩的岩石化学及稀土、微量元素地球化学特征，进一步阐明了构造－蚀变作用与金矿化的关系，即金矿化在空间上与围岩蚀变类型及强度关系密切，在时间上大致同期形成。这种由剪切构造变形作用引起的蚀变作用，对金矿化具有重要意义。

| Abstract: | Types and stages of wallrock alteration,petrochemistry,minor element and REE geochemistry of tectonic-altered rock in Gala shear zone type gold deposit in the northern sectino of the Garze- Litang fracture zone are discussed.Relation of the gold mineralization with structure and alteration is exPOunded.The gold mineralization is associated with wallrock alteration spatially and temporally.Wallrock alteration resulting form shear deformation is of importance to gold mineralization . |
