| 摘 要： | 杨斜地区石英脉型钨金矿床（点）主要分布在以沙河湾岩体为中心的北侧秦岭群内北北西向断裂中。钨、钨钼、铜、铅、锌等多金属及金、银矿化空间分布自南而北具有明显的分带性。同位素和包体资料表明成矿溶液主要为大气降水。钨金矿床（点）的形成与印支期花岗岩活动有关，岩体为成矿提供了主要金属元素。区内钨金、钨钼、铜、铅、锌及金银矿化规律性分布具有成矿系列的特点。

| Abstract: | The W-Au deposit (occurrences), being quartz vein type, is mainly distributed in NWW fault where is in northern Qinling Group and Shahewan rock body as a centre, It is distinct that zonation of W,W-Mo, Cu, Pb and Zn polymetals as well as the spatial distribution of Au and Ag mineralization present from south to north. Meanwhile, the isotopic and inclusion data show that mineralizing solution is mainly meteoric water. The formation of W-Au deposit (occurrences) is related with granite magma activity of Indo-Chinese epoch, and the main metal elements in ore-forming process is provided by the rock bodies. The regular distribution of W-Au, W-Mo, Cu, Pb, and Zn as well as Au-Ag mineralization in the region is characterized by metallogenetic series. |
