确定成岩成矿的准确年龄是进行矿床学研究的基础,然而在热液型矿床中由于缺少合适的定年矿物,使得准确的成矿年龄很难获得。传统方法是利用蚀变围岩中矿物的年龄来代表成矿年龄,但是,近年来,越来越多的研究表明蚀变矿物的年龄可能并非真正的成矿年龄(胡瑞忠等,2014),因此直接利用矿石矿物来确定成矿年龄是十分有必要的。黄铁矿在金矿床中普遍存在,是重要的载金矿物,常与金同时沉淀,因此对黄铁矿定年能够很好地确定成矿年龄。近年来,直接利用黄铁矿的Rb-Sr(Yang
Determining the exact age of diagenesis and mineralization is the basis of deposit study. However, due to the lack of suitable dating minerals, accurate metallogenic age is difficult to obtain in hydrothermal deposit. However, in recent years, more and more studies indicate that the age of altered minerals may not be the true age of mineralization (Hu Ruizhong et al., 2014), so the traditional method is to use the age of altered minerals in altered rocks to represent mineralization age The direct use of ore minerals to determine the age of mineralization is very necessary. Pyrite is ubiquitous in gold deposits and is an important gold-bearing mineral, which is often deposited simultaneously with gold. Therefore, dating of pyrite can well determine the ore-forming age. In recent years, direct use of pyrite Rb-Sr (Yang
