摘要
辽南地区是我国一个重要的黄金产地，分布有几十个大、中、小型金矿床。本文主要从辽南地区与金矿有着十分密切关系的中生代花岗岩类的成因特征入手，划分出两期不同类型的花岗岩，亦从花岗岩岩石地球化学特征方面讨论了花岗岩与金矿的成因关系，从而确定燕山早期花岗岩类是辽南地区最主要的成金花岗岩。
South Liaoning is one of important goldoccurring areas in China, where distribute dozens of large,middle,and smallscale gold deposits.In light of close relationship between gold deposits and Mesozoic granitoid, the paper divided the granitoid into 2 stages of granites, discussed their genesis relationship in the aspect of lithogeochemical characteristics, and then determined the early stage of Yanshanian granitoid is the most important goldforming granite.
