Geochronology of the Birim Supergroup of the West African craton in the Wa-Bolé region of west-central Ghana: Implications for the stratigraphic framework

Geochemistry and geochronology of granitoids in the Kibi-Asamankese area of the Kibi-Winneba volcanic belt, southern Ghana

“…This study shows that the Kibi-Asamankese area does not differ significantly from the other Birimian domains of the Leo Rise, with respect to the nature and age of emplacement of the granitoids (e.g., Abouchami et al, 1990;Taylor et al, 1992;de Kock et al, 2011;Sakyi et al, 2014). Three generations of granitoids can be recognised in the study area: the first generation is the Boynton (1984).…”

Discriminating fluid source regions in orogenic gold deposits using B-isotopes

“…This period is divided into two phases. Though there is regional variation, broadly the Eoeburnean (also known as Eburnean I or the Tangaean; 2266-2150 Ma) precedes the Eburnean (2216-1980 (Taylor et al, 1992;Dia et al, 1997;Loh et al, 1999;Allibone et al, 2002;Gueye et al, 2007;Tshibubudze et al, 2009;Hein, 2010;de Kock et al, 2011). The Eoeburnean consists of volcanism, granitoid emplacement and fold, thrust tectonics, and is interpreted by Tshibubudze et al, (2015) to be a single diachronous event across the Birimian.…”
