中文摘要：

西秦岭地区金矿资源丰富,找矿潜力巨大。为了探讨不同源区参与成矿的程度,对该区3个成矿亚带19个典型金矿床主成矿期流体包裹体及H、O、C、S稳定同位素特征进行研究,发现西秦岭地区成矿流体为岩浆水、变质水和大气降水混合来源,具有中低压、中低温和低盐度的特征,成矿物质为岩浆和沉积岩中碳酸盐岩的混合来源。西秦岭地区3个成矿亚带整体上具有明显的分带特征,自南向北其矿源具有从以混合来源为主向沉积来源过渡的趋势。

英文摘要：

Western Qinling Mountains is rich in gold resources, the area has a huge potential for prospecting.In order to investigate the mineralization extent of different ore-forming materilas, we analysis the fluid inclusion and stable isotope characteristics in the main mineralization stage of 19 main gold deposits from three metallogenic belts in Western Qinling Mountains,based on the results of previous studies.It was found that the metallogenic fluid of Western Qinling Mountain is a mixed origin consist by precipitation, metamorphic and magmatic water with characteristics low-pressure, low-temperature and low salinity, the ore-forming material is the mixed origin of magmatic and sedimentary rocks.From south to north,three metallogenic belts of Western Qinling Mountains have an obvious zonation features and it＇ s metallogenic fluid have a trend that shifting from mixed origin to deposit origin.
