| 中文摘要: |
| 通过钻探岩芯矿石光片、薄片显微镜鉴定，并结合地表的野外地质调查工作，对下屯铜多金属矿床矿石特征进行系统研究；根据矿石组构特征、矿物组成特征及金属矿物和脉石矿物组合、相互交叉生长关系，将矿床分为两个期次和四个阶段。初步认为该矿床为构造-热液叠加型多金属矿床。 |
| 英文摘要: |
| Based on microscopic identification of polished sections and thin sections of ore collected from core and field observation the ore characteristics of the Xiatun copper polymetallic deposit are systematically studied. Mineralization of the deposit can be divided into 2 metallogenic epochs and 4 stages according to fabric and minerology of the ore and assemblages of metal minerals and gangue minerals and their intergrowth. through identification of light flakes and thin slices under microscopes of drilling core and in combination with the outcrop data, and its rock fabric characteristics are summarized. According to the petrofabric features and relationships of combination and cross-growth between metal and gangue minerals, the metallogenic epoch of the deposit is divided into two periods and four stages. Ultimately, it is preliminarily determined that it's a structural-hydrothermal superimposition polymetallic deposit. |
