Preliminary Report on the Paleoproterozoic Metasediments Genesis and Features of the Banfora Belt Western Burkina Faso (West Africa Craton)
《International Journal of Geosciences》2025年第1期1-19,共19页Hermann Ilboudo Bernadin Gnamou Wilfried Antoine Bassou Toe Marc Ephrem Allialy 
Metasedimentary rocks of the Banfora belt are examined for their petrography geochemistry and genesis. The main formations are pelite metapelites sandstone, and metagraywackes. The first ones show a fine interlocking ...
