Abstract
In the process of the formation of classical lateritic bauxites in the Futa Jallon-Mandingo province, due to a complex of two- to three-stage genesis, lithological and genetic types of bauxites were formed that differed in external characteristics, color, texture, and structure. The proposed genetic typification of bauxite based on textural and structural features of the rocks in fact is the basis for the geological and industrial classification of deposits of the region. Studying the textural and structural features of bauxites is the only way through which one can get an idea of the conditions of their formation. It is in the textures and structures of ores their genetic history is imprinted. The analysis shows that the deposits, within which deposits of sedimentary-lateritic and chemically transformed bauxites predominate, are distinguished not only by greater thicknesses of ore bodies and a significantly higher content of total alumina in the ores, but also by increased contents of monohydrate forms. This also determines various economic indicators of the operation and technology of metallurgical processing of bauxite.
期刊介绍：
Geology of Ore Deposits is a periodical covering the topic of metallic and nonmetallic mineral deposits, their formation conditions, and spatial and temporal distribution. The journal publishes original scientific articles and reviews on a wide range of problems in theoretical and applied geology. The journal focuses on the following problems: deep geological structure and geodynamic environment of ore formation; distribution pattern of metallogenic zones and mineral deposits; geology and formation environment of large and unique metallic and nonmetallic deposits; mineralogy of metallic and nonmetallic deposits; physicochemical and isotopic characteristics and geochemical environment of ore deposition; evolution of ore-forming systems; radiogeology and radioecology, economic problems in exploring, developing, and mining of ore commodities.
