| 摘 要： | 新疆阿希金矿床为西天山一典型的形成于晚古生代的与火山岩有关的大型浅成热液金矿床.电子显微探针微区成分分析结果显示,该矿床黄铁矿具有富砷贫硫的特点,w(Co)/w(Ni)比值主要介于1.79～4.61之间,反映出成矿流体以岩浆热液为主,而其比值在环带结构富砷黄铁矿核部(＞5)及环带(＜1)中的变化规律则进一步反映出成矿早... |

| Abstract: | Axi gold deposit,existing in West Tianshan Mountain,Xinjiang,is a type of large volcanic-related epithermal gold deposit formed in the Paleozoic era.Electron microprobe(EMP) analysis shows that the pyrites are characterized by being rich in As and poor in S.That the Co/Ni of pyrites varies mainly from 1.79 to 4.61 suggests the ore fluids come mostly from magmatic hydrothermal solution probably.Furthermore,the ratio variation from the cores(>5) to the rims(<1) of the zoned arsenopyrites suggests the particip... |
