Dataset of lead isotope ratios of lead ores. KU Leuven
This database was compiled from the literature. All samples analysed prior to 1980 are excluded, due to poorer precision before that date. The ores have been placed in groups corresponding to countries or important regions. In most papers the ratios 208Pb/206Pb, 207Pb/206Pb and 206Pb/204Pb were given. The ratios 208Pb/204Pb and 207Pb/204Pb shown have been calculated from the other values. All samples which were published with only two isotope ratios are excluded.
