International metallogenic map of Africa

International metallogenic map of Africa

A major objective was achieved with the publication of the International Metallogenic Map of Africa, produced by the Council for Geoscience (Geological Survey of the Republic of South Africa) under the aegis of the CGMW.

This map replaces the first edition of the Map of Mineral Deposits of Africa, of which only sheet 1 (NW) was published in 1991. The mineralogical data (location, names of the main deposits, mineral resources present, characteristics of occurrences and size) have been transferred to a geological base based on the International Geological Map of Africa at 1:5 M (1985-1990), updated from time to time.

This background shows the chronostratigraphic succession of sedimentary and volcanic sequences and plutonic bodies, the geodynamic framework of orogenic domains and the petrogenetic environment, with a lithological distinction between magmatic and metamorphic rocks. Mineralogical deposits were counted and referenced according to a 5° x 5° latitude/longitude grid.

The GIS data for the map are marketed by the Council for Geoscience (www.geoscience.org.za)

General coordinator: E. C. I. Hammberbeck, Chairman of the CCMG Sub-Commission on Metallogenic Maps until August 2004.
Principal compilers: Mrs. M. Veselinovic-Williams and S. Frost-Killian, Council for Geoscience (Geological Survey of the Republic of South Africa), with contributions from numerous collaborators and editors from African Geological Surveys and universities.
