Project 638 - Paleoproterozoic Birimian geology for sustainable development

Project Updates - 2022


The 5th Colloquium of the IGCP 638 on the geodynamics and mineralization of the West African Craton (WAC) will be held in Accra at the University of Ghana from the 4th to the 5th of December, followed by a field trip from the 6th to 9th of December. 

The sets of themes of the conference will relate to geodynamics, mineralization, geochemistry, geochronology, geophysics, mapping, lithology, sedimentology, imagery, environment (pollution and deforestation related to mines), climate change, and other related subjects. The events and targets are expected to: (i) generate active exchanges between the actors of the field (enquiring, expert mining); (ii) produce scientific knowledge on the geology of the WAC for the benefit of academia and teaching programmes and facilitate mining exploration; (iii) reinforce the capacity of the participants on the field methods of the Paleoproterozoic (Birimian) basement geology by the means of field trips (possible sampling of specimens).

Brief outline of the project

This IGCP project is focused to the knowledge of bearing mineralizations (particulary goldbearing mineralizations) related to the geodynamic evolution of the old terrains (dated between 2300 and 2000 million years); known as Birimian formations (Paleoproterozoic) in West Africa.

The characterization of the Birimian terrains will be investigated through structural, metamorphic, geochemical, geochronological and geophysical data at variousscales. The goal is to understand the relations existing between the history of the orogen and the development of the particularly rich and dense metal concentrations of economic interest within the Birimian domain. This natural resource, that we will contribute to emphasize through this project, will widely take part in the economic and social development of our states.In addition, the knowledge of the Birimian geodynamics could take parting the complement of the “curricula” of the secondary education of our West African countries. Indeed, these programmes are currently deprived of chapters on the geology of Precambrian of mining resource of West Africa (geodynamic) fault of precise knowledge in this field.

The results of this project will also allow the public authorities to have scientific guides for the improvement of the mining tools and the education policies in the areas concerned.
