Abstract

Two groups of bauxites developed on dolerite and shale yield the same mineral paragenese. The differences of mean Al2 O3 and Fe2 O3 content in both groups are expressed entirely by differences of concentration of gibbsite and goethite, which reflect mobility of aluminium and iron in solutions circulating through the system of open large pores. Boehmite and hematite would tend to crystallize from oversatured solutions in confined environment of fine pores
