... to be a temporal association with the 2100 Ma onset of transpression/strike-slip and exhumation. However, ore deposition was likely spread over at least 130 m.y. throughout the shield, with some ores as old as ca. 2160 Ma (e.g., Wassa) and some no older than ca. 2030 Ma (e.g., Damang). It is unclear as to exactly...
