U-Pb SHRIMP geochronology data from the eastern Central Kibalian Superterrane, Bomu-Kibalian Craton, northeastern DRC: Implications for the tectonic evolution of the Kilo Terrane

摘要

This brief presents new U-Pb SHRIMP (Sensitive High-Resolution Ion Microprobe) geochronology data on zircons and titanites dated from the gold-rich Kilo Terrane in the eastern Central Kibalian Superterrane, northeastern DRC. Out of 40 rock samples (), only 36 samples produced zircons and titanites suitable for U-Pb SHRIMP dating (-). Raw ion-microprobe SHRIMP analyses of specific zircon/titanite grain-spots returned U-Th-Pb compositions and radiogenic isotope ratios (-), from which age dates (, Figs 8A-8HH and 13A-F) were derived. With the exception of , all Tables are presented in the Supplementary Material. The new age dates in this Brief can be used in advancing understanding of the gold metallogeny and implications to exploration targeting for large to giant gold deposits in the Bomu-Kibalian Craton.
