| Abstract: | 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. |
