1. U-Pb, O and Lu-Hf isotope ratios of detrital zircon from Ghana, West-African Craton : formation of juvenile, Palaeoproterozoic crust
University essay from Lunds universitet/Geologiska institutionenAbstract : Detrital zircon were sampled from five rivers in Ghana and they were analysed in situ for U-Th-Pb, O and Lu-Hf isotopes. Based on the analyses, their U-Pb crystallisation ages, δ18O isotope ratio, εHf and Hf-model ages were determined. This provides information about the origin and crustal evolution of the Palaeoproterozoic bedrock in Ghana. READ MORE
