云南金厂金矿床铬绢云母系列成因矿物学特征与找金标志

GENETIC MINERALOGIC FEATURES OF CHROME－ SERICITE MTNERAL SERIES FROM THE JINCHANG GOLD DEPOSIT,YUNNAN PROVINCE AND THE MARK FOR GOLD DEPOSIT PROSPECTING

通过 57个电子探针分析，配合其它分析测试方法，将金厂金矿床铬绢云母系列划分为 2个矿物类 10个矿物种和 3个生成世代，并总结出其成因矿物学特征，提出铬绢云母系列的生成与金矿的形成关系密切。铬绢云母系列是该区找金的重要标志。

This study is based on fifty－ seven electron microprobe analyses,one wet method chemical analysis,three INAA,one DTA and three powder X－ ray diffraction analyses of Chrome－ Sericite mineral series from the Jinchang gold deposit,Yunnan province. Chrome－ Sericite mineral series from Jinchang gold deposit is classified into two mineral groups,ten mineral types and three mineral generations. And its genetic mineralogic features are summed up in this paper. It is put forward that there is a close relation between the forming of Chrome－ Sericite mineral series and gold ore. The appearance of Chrome－ Sericite mineral series is an important mark for gold deposit prospecting in this area.
