摘　　要：用分形理论研究了胜利达圾金矿区花岗质岩石中金含量的分布特征，得出花岗质岩石的金是在韧性剪切活动中被激化的。一部分金被迁移至相邻的黄铁矿化的花岗质糜棱岩中，所构成的金矿（化）体规模大，但金品位低，与围岩没有明显的界线；而另一部分金则被迁移至其他的岩石中去。The distributive characters of Au content in granitic rocks from Au mineralized district inShenglidaban has been studied with fractal theory,The study indlcates that, during ductile shearactiveity,certain part of Au orebodies formed in this way is usually in large-scale,but Au grade isrelatively low and there is no distinct boundary between the orebody and its country rocks.Anotherpart of Au,however,is migrated to other orebodies.
