Дан комплексный геолого-экономический анализ наиболее важных особенностей формирования минерально-сырьевой базы Африканского континента на современном этапе с учетом ретроспективных (с конца XIX в.) и перспективных (до 2010 г.) тенденций. Рассмотрена геолого-экономическая отраслевая характеристика различных видов твердых полезных ископаемых, учтена роль африканского минерального сырья в мировом капиталистическом хозяйстве и в индустриализации развивающихся стран континента.
Для специалистов, занимающихся экономикой минерального сырья за рубежом.

In July 1975, we began a lifetime of interest in the Kenya Rift lakes when we began as graduate students supervised by the late Professor WW (Bill) Bishop at Queen Mary College, University of London.

The notion that mining can contribute positively to the economic and human development of mineral wealth countries makes a lot of sense, especially given the huge revenue mineral wealth developing countries can generate from the sector to alleviate poverty.

Composition and evolution of fluids depositing tin and tungsten ores in Kibaran quartz vein deposits allow the modelling of devolatizing evolved granites as their source at depth. Fluids forming gold quartz veins and breccias are different from the first, especially by showing characteristics of a high-pressure environment. All deposits are controlled by compressional deformation whose fading phases affect earlier formed veins. These findings lead to the conclusion that both anatectic melting resulting in intrusion of fertile granites, and the generation of fluids forming gold deposits are the final consequence of deep crustal metamorphism. The latter was caused by crustal thickening immediately preceding the metallogenetic climax. <...>

The Kibara belt is an intracontinental mobile belt formed between 1400 and 900 Ma within a craton of Lower Proterozoic age. The belt's evolution started by early rifting at about 1400 Ma, and continued by transition into a marine basin filled by clastic sediments > 10 km thick, with minor basic and acidic volcanic rocks. At about 1300 Ma, the pile was deformed by thrusting and folding of the main Kibaran Orogeny and intruded by numerous large syn-orogenic granite bodies.

Te mining sector is essential in the economic development of many resource rich African countries as it has the potential to fnance infrastructural developments which are much needed in Africa. Tis is due to the fact that various minerals are used as raw materials in different sectors including construction and transport. Most importantly, mineral materials also play an important role in industrialization and urbanization which are now rapidly escalating on the continent.
