摘　　要：几内亚共和国博凯558铝土矿为一处超大型风化残积三水铝石型铝土矿床。赋矿岩系的矿物组分呈上部富集三水铝石、赤铁矿;下部富集石英、白(水)云母、高岭石等。赋矿岩系的化学组分呈上部富集Al2O3、Fe2O3等,下部富集SiO2等。矿体赋存于赋矿岩系的上部铁矾土、铁红土内。558 Bauxite in Boke district, Guinea, is a super-large weathered residual gibbsite-type deposit discovered by our crew. In the ore-boring rocks,the upper minerals are mainly gibbsite and hematite, and the underside is rich in quartz, muscovite,kaolinite and so on. As for the chemical compositions of ore-boring rocks, the upside is rich in Al2O3, Fe2O3 and the underside is rich in SiO2. The orebodies occure in the upper layer of laterite.
