| 摘 要： | 扎村金矿为中-低温热液型金矿床。黄铁矿是最主要的载金矿物，其含金性与成矿期次有着密切连系。分粗粒、中细、细粒、微细粒四种类型，其含金性随着黄铁矿的粒径变细而降低。粗粒黄铁矿含金性最好（10～25．5）g／t；其次中细粒为（3—7．35）g／t；微细粒基本不含金。

| Abstract: | The Zacun Au deposit is a Au Deposit of middle - low T hydrothermal type. The pyrite is the main Au - bearing mineral. The Au - bearing ability is close related with the metallogenetic stage. The pyrite can be divided into 4 types of coarse, middle -fine, fine, impalpable structure. The Au - bearing ability of coarse pyrite is the best one, 10 - 25.5 g/t, middle - fine pyrite is the second one, 3 - 7. 35 g/t. The impalpable pyrite basically doesn＇ t bear any Au. The Au - bearing ability declines as the grain-size of pyrite decreases. |
