四川某金多金属矿床地质特征及成因探讨
摘要
该金多金属矿床赋存于花岗岩过渡相及边缘相部位
主要受断裂构造控制;矿脉形态为豆荚状及脉状
与围岩接触界线清楚
呈突变过渡;矿石中金粒结晶微细
扩散交代作用微弱
金属矿物多属中温矿物;其矿床成因类型隶属中温热液充填型矿床
产出地质特征分类应属破碎带蚀变岩型金矿床。
Abstract
The Au-polymetal deposit occurs in granite transitional facies and marginal facies
mainly controlled by fracture structure. The pattern of Vein is the podiform and vein
contact with the surrounding rock boundaries clear
showed by mutation transition. Gold grains with fine crystallization In the ore
diffusion metasomatism is weak
metal minerals are medium temperature. The genetic types of ore deposits belong to the warm liquid filling type deposit. Geological characteristics of classification should be belong to the gold deposit of alteration rock type in the fracture zone.
