摘要
斑岩型金矿床作为现今社会主要工业类型的金矿,为世界提供了超过55% 的金.这种矿床的特征表现为吨位大、低品位,比较容易开发利用.金矿的形成作为一个多种物质来源、极其复杂的地质构造演变与成矿地质条件反复叠加的过程,其过程依然会存在一定的规律可找.基于此,提出斑岩型金矿床成矿地质条件分析与探讨,对其红泥塘岩体构造以及地壳厚度及速度结构分别进行阐述.
Porphyry gold deposits,as the main industrial type of gold deposits in today's society,provide more than 55%of the world's gold.This deposit is characterized by large tonnage and low grade,and is relatively easy to develop and utilize.The formation of gold deposit is a process of multiple material sources,extremely complex geological structure evolution and repeated superimposition of metallogenic geological conditions.There are still some rules to be found in the process.Based on this,the metallogenic geological conditions of porphyry gold deposits are analyzed and discussed.The structure of Hongnitang rock mass,crustal thickness and velocity structure are expounded respectively.
