Abstract
U-Pb and Pb isotopic measurements of cassiterite from the ~200 Ma tin deposits of Belitung, Indonesia, and ~2100 Ma Zaaiplaats deposit in South Africa demonstrate that cassiterite can be used to directly date mineral deposits, rather than associated minerals such as zircon and rutile. A precise U-Pb age of 2099 ± 3 Ma has been determined for cassiterites hosted in granites from the Bushveld Complex. On conventional 207Pb/204Pb-206Pb/204Pb plots, the data for the Indonesian deposits give an age apparently older than that obtained from U-Pb plots, perhaps indicative of inheritance of Pb from an older source. -Authors
