| 摘 要： | 矿带位于雪峰隆起中段,主要赋存于板溪群五强溪组的一套火山沉积浅变质岩系中。矿体成群成组出现,成带分布,具有明显的方向性与近似等距性。成矿元素与赋矿地层中高含量微量元素有一定对应关系。在区域变质过程中,经中低温热液淋滤作用,以特殊的含锑(金)硫的碱性络合物和钨的杂多酸形式迁移,在有利的控矿构造部位聚集成矿,属火山沉积-变质热液类型矿床。

| Abstract: | Zhazaixi antimony belt is situated in the middle part of Xuefeng upheaval. The mineralization occurs mainly in the slightly metamorphosed volcanogenic sedimentary rock sequence of Wuqianxi Formation of Banxi Group. Orebodies were found in groups and distributed zonally, and are of strong orientation and approximately equal in distances. The ore-forming elements are to some extent in correspondance with the high-content trace elements of ore-hosting strata. In the regional metamorphic process, through meso-epithermal hydrothermal leaching, the ore-forming material migrates in the form of special antimony (gold)-bearing alkaline complexes and tungsten heteropolyacid and accumulates in favorite structural position to form ore deposit. It belongs to volcanic sedimentary-metamorphic hydrothermal type deposit. |
