英文摘要Contrary to what is currently known, archetypal zircon samples from gneisses and intrusive leucogranites in the Palaeoproterozoic Suhum Basin, SE Ghana, suggest the involvement of Neoarchean crustal material in the formation of the Palaeoproterozoic juvenile crust of the Birimian terranes in Ghana. The zircons dated using U-Pb dating methods and subjected to Lu-Hf isotopic analysis suggest that crustal-forming events from different contemporaneous magmatic episodes within the Suhum Basin took place over a time interval of 139 Ma from 2224 to 2085 Ma. Whole-rock Lu-Hf data obtained for the gneissic and leucogranitic rocks gave model ages (T-DM2) ranging from 2789 to 2456 Ma with eHf(t) values ranging from -1.1 to +5.4. These model ages imply that the magmas that formed these rocks were sourced from the early Palaeoproterozoic juvenile mantle with substantial Neoarchean crustal reworking.
