摘要
本文介绍了小秦岭金矿带的成矿地质背景,各期花岗岩的分布与产出特征,以及岩性与物质组分特征。并认为花岗岩在金矿床形成中起了“热发动机”的作用,是本区金元素活化迁移的热动力中心,对金矿床起了重要的迭加改造作用,是小秦岭金矿节重要的控矿因素。
In this paper, the metallogenic geological setting of Xiao Qinling gold deposit belt, the occurence and distribution of the granitoids with different phases, and the characteristics of litholgy and compositions are discussed. It is suggested that the granitoids played a role as heat engine in the ore-forming process of the gold deposits. The so called heat engine was a thermodynamic center making the activation and migration of gold elements in this area. Therefore it was an important ore-coutrolling factor which played an important role in the reformation and superimposition of the gold deposits.
