Pb-Pb Isotopes - Pb207/Pb204 Grid (Regolith) December 2023

This is an interpolated grid of Pb-Pb isotope data (Pb207/Pb204) obtained from the analysis of Australian regolith samples. The point data used for the interpolation are from the Pb-Pb regolith dataset held in Geoscience Australia's Isotopic Atlas as of December 2023. Point data added to the Isotopic Atlas after December 2023 is not represented in this grid. The grid is an ‘Inverse distance weighting’ (IDW) interpolation produced with the Grid (IDW with Nearest Neighbor Searching) or invdistnn GDAL tool in QGIS, with a weighting power of 2 and minimum/maximum nearest neighbouring points of 6/12.
