| 摘 要： | 乐家湾锑太和是粤北锑矿带上的典型矿床。围岩蚀变具有很好的分带性，从矿体向围岩依次为锑矿化带、硅化蚀变带和黄铁矿化蚀变带，蚀变前后每１００ｃｍ＾３中的组分置换可达２０３．３８ｇ。通过成矿作用过程、稳定同位素和包裹体的研究分析，作者认为乐家湾锑矿床属层控－低温热液叠加成因。

| Abstract: | Lejiawan antimony deposit is a typical deposit in the antimony mineralization zone in northern Guang Dong Province. Zoning of mineralization and alteration in Lejiawan antimony deposit is very distinct, from orebody to country rock there are antimony mineralization belt, silification belt and pyritization belt, respectively. Based on the investigations and analyses of the ore forming process, isotopic data and fluid inclusion data, the authors suggest that the genesis of Lejiawan antimony deposit belongs to stratabound epithermal transformation deposit. |
