| 摘 要： | 在详细论述桂东地区金矿床赋存的构造地质环境，控矿地层岩性及岩浆活动与金矿化与关系等成矿地质特征基础上，通过矿石微量元素和稀土元素特征及硫，铅，氢氧稳定同位素组成特征研究证实，在矿物质以深源岩交为主，混有少量壳源物质成矿流体为岩浆水，后期混有少量变持水和大气降水，矿床具有多源，多成因及多期次成矿特征，矿床成因类型主要有岩浆热液，变质热液和复合叠加类型，而以后者为主。

| Abstract: | ectonic and geololgical background, ore-controling strata and magmatism related to Au de-posits in East Guangxi are detailed in this paper. Evedences of minor element. REE. S,Pb, H,O isotope analysis reveal that ore fluid is dominated by magmatic water and incorporated with some metamorphic water and meteoric water. The Au depolsits are characterized by multi-sources and multi-perioldical metallogeny. Au ore deposits are classified intol magmatic hydrol thermal flu-id type and metamolrphic fluid and superimpostion types. |
