Projet 638 - Paleoproterozoic Birimian geology for sustainable development

Projet du PICG - réunion 2018

3rd Colloquium of the IGCP 638 on Geodynamics and mineralizations of Paleoproterozoic formations for a sustainable development

  • 15-16 October 2018, University Félix Houphouët-Boigny, Abidjan, Côte d'Ivoire

It will join together the international scientific community. The sets of themes of the conference will relate to geodynamics, mineralizations, geochemistry, geochronology, geophysics, mapping lithology, sedimentology, imagery, environment (pollution and deforestation related to mines)

The events and targets are:

  • generate active exchanges between actors of the field (enquiring, expert mining
  • produce scientific knwoledge on the geology of the WAC for an update of the academic and school programmes and facilitate mining exploration
  • reinforce the capacity of the participants on the field methods of the Paeloproterozoic (Birimian) basement geology by the means of field trips


Bref résumé du projet

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.
