| 摘 要： | 山东招掖金矿带的金矿床受花岗岩类型及构造控制,使其分布很不均匀。金矿化集中发育在栖霞—掖县复背斜翼部的交代花岗岩中,受北东向压扭性断裂控制,而在复背斜核部的重熔花岗岩中很不发育。本文通过构造-花岗岩的控矿作用,对本区金矿控制条件提出了新的看法:①构造-岩浆控制了金矿床的空间展布;②构造-岩浆演化控制了金矿的成矿演化;③内生成矿作用与构造-岩浆作用有密切的成因联系。

| Abstract: | Almost all gold deposits in Zhao-Ye ore zone were discovered in granitic rock, they are distributed very unequally in different types of granites and different locations of structures. Gold mineralization is concentrated in the metasomatic granites at the limbs of Qixia-Yexian anticlinorium, controlled by NE compressive-shearing fractures, whereas in anatectic granite in the middle sector of this anticlinorium, there is no gold deposit discovered. In this paper, according to the ore-controlling significance of structure-granite, the authors put forward some new views on the geological conditions of gold mineralization in this area. 1. Structure-magmatite controls the distribution of gold deposits. 2. The evolution of structure-magmatite controls the evolution of endogenic mineralization. 3. There is close genetic relation between endogenic mineralization and structure-magmatism. |
