广东省小坑金矿地质特征及成因浅析

Analysis of Geological Characteristics and Genesis of Xiaokeng Gold Deposit in Guangdong Province

文章对小坑金矿地质特征进行了详细的阐述,认为区内成矿地质条件十分有利,主要构造线为北西走向,区内岩浆活动强烈,围岩蚀变中矽卡岩化、硅化和毒砂矿化与金矿化关系密切,地球化学异常强度高、规模大。并浅析矿床类型,推测为矽卡岩型金矿床。

This article elaborates the geological characteristics of the Xiaokeng gold deposit. It is believed that the metallogenic geological conditions in the district are very favorable. The main tectonic line is in the northwest direction. The magmatic activity in the area is intense, and the skarnization and silicification in the wall rock alterations. Mineralization with arsenopyrite is closely related to gold mineralization, with high geochemical anomaly intensity and large scale. The types of deposits are inferred to be skarn gold deposits.
