摘要
通过对新泰地区花岗绿岩带基本地质特征、金的初始丰度及其后生变化、花岗质岩石金含量的研究 ,探讨了火山喷发沉积作用、变质作用、岩浆作用及构造作用对金的活化与迁移的影响。结合对区域地质背景及演化史的分析 ,认为该区绿岩型金矿具糜棱岩型和石英脉型两种类型 。
Through study on basic geological characteristics, gold primary abundance and its deuterogenic variation, and granites gold content in Xintai granitic greenstone belt, volcanic eruption-sedimentary, metamorphism, magmatism and tectonization effects to gold activation and transportation have been discussed. Considering the regional geological background and its evolution history, it is said that greenstone type gold deposit has two types as mylonite type and quartz-vein type, and it belongs to multi-sources and multi-stages hydrothermal-filling type gold deposit.
