摘要
通过对砂锅厂红土型金矿床化学组成 (常量元素、微量元素、稀土元素 )的研究 ,根据矿床地球化学特征 ,探讨了矿床的物质来源 ,推断其矿源体为浅成低温热液金矿床 (体 ) ,属微细侵染型金矿其矿石系黄铁矿化、毒砂化富金玄武质凝灰岩类风化的产物 ,初步分析了此类矿床的成矿作用机理。
Based on study of Chemical composition of macro_elements, micro_elements and REE at Shaguochang lateritic gold deposit in southwestern Guizhou province, the material sources of the lateritic gold deposit is discussed in accordance with geochemical feature of this deposit. The source body is inferred to epithermal gold deposit or body and the ores can be formed from weathering Au_rich pyritized and arsenopyritized basaltic tuff et.al.. Mineralization mechanism of this type deposit is analysed.
