| 摘 要： | 岷礼东部－湘潭子一带蕴藏着甘肃省最大的金矿床和铅锌矿庆。主要控矿地层为中泥盆统，该套地层地球化学条件优越，断裂构造十分发育，岩浆活动非常强烈，是金及多金属矿床的有利成矿地段。区内矿床可划分为四大系列，６个类型。利用地球化学特征，分析主要控矿因素对成矿的控制作用；总结主要矿种的成矿规律；筛选出３个找矿远景区。

| Abstract: | There might be the largest gold and lead-zine deposits in the eastern part of Minli-Xi-angtanzi , Gansu. These deposits were controlled by the middle Devonian in which the geo-chemical conditions,well developing faulted structure and magmatic activity intensely, all of these are favorable for the mineralization of gold and polymetallic deposits. The deposits in this district were classified into four metallogenetic series and consist of six types. The author analysed main ore-controlling conditions with the geochemical characteristics and concluded a ore-forming regularity and got three exploration districts. |
