| 中文摘要: |
| 宁乡-新宁断裂南东盘燕山早期花岗斑岩岩脉带(包括少量石英斑岩)呈325°～340°方向展布,它们应是加里东期宁乡-新宁断裂形成时反扭作用产生的羽状张裂隙被燕山早期花岗岩浆所充填的结果.沿岩脉带及其附近分布着较多的内生金属矿产都具有相同的矿床组合,并且形成从北西向南东由中低温-中温-中高温的成矿系列.即由金、锑金→锑→铜铅锌→钨的递变特征.在岩脉带分布的范围内,构成了一个以锑、金、铅锌、钨为主的多金属矿带.在成矿带的北西侧以锑、锑金为主.构成了一个以锑、金为主的成矿区.在成矿带的南东侧以铅锌铜钨为主,构成了一个Pb、Zn、Cu、W成矿区. |

| Granoporphyric dykes (including some felsie porphyries) in the southeast plate of Ningxiang-Xining fracture occur as zones trending in direction of 325-340°. They are granitic magma intrussives of the Early Yanshan Period filled in tensional plume fissures taking place in the process of anti-tortion when Ningxiang-Xinning fracture was formed. Endogenie metal mineral resources are located along them with similar association of Au, Sb-Au-Sb-Cu-Pb-Zn from lower-medium temperature to high temperature metallogeny. The northwest side is dominated by Sb, Sb-Au and southeast by Pb, Zn Cu w. |
