Geochronology And Isotopes This web service provides access to the Geoscience Australia (GA) ISOTOPE database containing compiled age and isotopic data from a range of published and unpublished (GA and non-GA) sources. The web service includes point layers (WFS, WMS, WMTS) with age and isotopic attribute information from the ISOTOPE database, and raster layers (WMS, WMTS, WCS) comprising the Isotopic Atlas grids which are interpolations of the point located age and isotope data in the ISOTOPE database. This internal database is only publicly accessible through the web service. The data structure currently supports summary ages (e.g., U-Pb and Ar/Ar) as well as extended system-specific tables for Sm-Nd, Pb-Pb, Lu-Hf and O- isotopes. ISOTOPE and the data holdings were initially developed as part of the Exploring for the Future (EFTF) program. Complete analytical data for GA results are available from Geochron Delivery: http://www.ga.gov.au/geochron-sapub-web/.

The point data used for the interpolation is the median magmatic epsilon Hf data from the summary Lu-Hf dataset held in the Isotopic Atlas as of February 2021. Point data added to the Isotopic Atlas after February 2021 is not represented in this grid. The grid was generated with Esri's ArcMap Spatial Analyst interpolation tool using the Natural Neighbor algorithm and 0.01 degree cell size. Two classifications are provided for this grid; a Jenks natural breaks classification with ten classes (classification 1) as per Champion (2013) http://pid.geoscience.gov.au/dataset/ga/77772, and; the same eight-class interval binning and colour scheme applied to the source point data in the Lu-Hf Isotopes - Summary Data layer (classification 2). 128.356727 -24.134164016647095 139.836727 -11.904164002361881 isotope:luhf_magmatic_ehft_grid image/png image/jpeg text/plain application/vnd.ogc.gml text/xml application/vnd.ogc.gml/3.1.1 text/xml text/html application/json EPSG:3857 EPSG:3857:0 0 0 0 0 EPSG:3857:1 1 1 1 1 EPSG:3857:2 2 2 3 3 EPSG:3857:3 4 4 6 7 EPSG:3857:4 8 9 13 14 EPSG:3857:5 17 18 27 28 EPSG:3857:6 34 36 54 56 EPSG:3857:7 68 72 109 113 EPSG:3857:8 136 145 219 227 EPSG:3857:9 273 291 438 454 EPSG:3857:10 546 582 877 909 EPSG:3857:11 1092 1165 1754 1819 EPSG:3857:12 2184 2331 3508 3639 EPSG:3857:13 4368 4662 7016 7278 EPSG:3857:14 8737 9324 14033 14556 EPSG:3857:15 17475 18648 28067 29112 EPSG:3857:16 34950 37297 56134 58224 EPSG:3857:17 69901 74594 112269 116448 EPSG:3857:18 139803 149189 224538 232897 EPSG:3857:19 279606 298379 449077 465795 EPSG:3857:20 559213 596759 898154 931591 EPSG:3857:21 1118427 1193519 1796308 1863183 EPSG:4326 EPSG:4326:0 0 0 1 1 EPSG:4326:1 1 1 3 3 EPSG:4326:2 2 2 6 7 EPSG:4326:3 4 5 13 14 EPSG:4326:4 9 10 27 28 EPSG:4326:5 18 20 54 56 EPSG:4326:6 36 40 109 113 EPSG:4326:7 72 81 219 227 EPSG:4326:8 144 162 438 454 EPSG:4326:9 289 324 877 909 EPSG:4326:10 579 649 1754 1819 EPSG:4326:11 1159 1298 3508 3639 EPSG:4326:12 2318 2597 7016 7278 EPSG:4326:13 4637 5194 14033 14556 EPSG:4326:14 9275 10388 28067 29112 EPSG:4326:15 18551 20777 56134 58224 EPSG:4326:16 37102 41554 112269 116448 EPSG:4326:17 74204 83109 224538 232897 EPSG:4326:18 148408 166219 449077 465795 EPSG:4326:19 296817 332439 898154 931591 EPSG:4326:20 593634 664879 1796308 1863183 EPSG:4326:21 1187269 1329759 3592616 3726367 Pb-Pb Isotopes - Regolith Data A compilation of full analytical data tables for publicly-available Pb-Pb isotope data for regolith samples from both Geoscience Australia (GA) and literature-compiled sources.

The data provides an estimate of the timing of extraction from the mantle of the middle to lower crustal source regions from which the felsic melts were generated. The point data used for the interpolation is the “felsic igneous rock” subset of the Sm-Nd data held in the Isotopic Atlas as of July 2024. Point data added to the Isotopic Atlas after July 2024 is not represented in this grid. The grid is a Natural Neighbours interpolation with a cell size of 0.01 degrees, generated using the nn C code library published at https://github.com/sakov/nn-c. Two classifications are provided for this grid; a Jenks natural breaks classification with ten classes (classification 1) as per Champion (2013) http://pid.geoscience.gov.au/dataset/ga/77772, and; the same nine-class interval binning and colour scheme applied to the source point data in the Sm-Nd Isotope Data layer (classification 2). 114.65793991725847 -43.74337909038955 152.94913107696533 -11.622379833967258 isotope:smnd_t2dm_grid_july_2024 image/png image/jpeg text/plain application/vnd.ogc.gml text/xml application/vnd.ogc.gml/3.1.1 text/xml text/html application/json EPSG:3857 EPSG:3857:0 0 0 0 0 EPSG:3857:1 1 1 1 1 EPSG:3857:2 2 2 3 3 EPSG:3857:3 4 5 6 7 EPSG:3857:4 8 10 13 14 EPSG:3857:5 17 20 26 29 EPSG:3857:6 34 40 52 59 EPSG:3857:7 68 81 104 118 EPSG:3857:8 136 162 209 236 EPSG:3857:9 272 325 419 473 EPSG:3857:10 545 650 838 947 EPSG:3857:11 1090 1301 1676 1894 EPSG:3857:12 2181 2602 3352 3788 EPSG:3857:13 4362 5205 6705 7576 EPSG:3857:14 8724 10410 13410 15152 EPSG:3857:15 17449 20820 26820 30305 EPSG:3857:16 34898 41641 53640 60611 EPSG:3857:17 69796 83282 107281 121223 EPSG:3857:18 139593 166564 214563 242446 EPSG:3857:19 279187 333128 429126 484892 EPSG:3857:20 558375 666256 858253 969784 EPSG:3857:21 1116750 1332512 1716506 1939569 EPSG:4326 EPSG:4326:0 0 0 1 1 EPSG:4326:1 1 1 3 3 EPSG:4326:2 2 2 6 7 EPSG:4326:3 4 5 13 14 EPSG:4326:4 9 11 26 29 EPSG:4326:5 18 23 52 59 EPSG:4326:6 36 47 104 118 EPSG:4326:7 72 95 209 236 EPSG:4326:8 144 190 419 473 EPSG:4326:9 289 380 838 947 EPSG:4326:10 578 760 1676 1894 EPSG:4326:11 1156 1521 3352 3788 EPSG:4326:12 2312 3043 6705 7576 EPSG:4326:13 4624 6086 13410 15152 EPSG:4326:14 9249 12173 26820 30305 EPSG:4326:15 18499 24347 53640 60611 EPSG:4326:16 36999 48694 107281 121223 EPSG:4326:17 73999 97388 214563 242446 EPSG:4326:18 147998 194777 429126 484892 EPSG:4326:19 295996 389555 858253 969784 EPSG:4326:20 591993 779111 1716506 1939569 EPSG:4326:21 1183986 1558223 3433013 3879138 Igneous Crystallisation Age Grid This grid is an interpolation of magmatic (igneous crystallisation) age point data held in the Isotopic Atlas as of February 2021.

The data provides an estimate of the timing of extraction from the mantle of the middle to lower crustal source regions from which the melts were generated. The point data used for the interpolation is the median magmatic T2DM data of the summary Lu-Hf dataset held in the Isotopic Atlas as of February 2021. Point data added to the Isotopic Atlas after February 2021 is not represented in this grid. The grid was generated with Esri's ArcMap Spatial Analyst interpolation tool using the Natural Neighbor algorithm and 0.01 degree cell size. Two classifications are provided for this grid; a Jenks natural breaks classification with ten classes (classification 1) as per Champion (2013) http://pid.geoscience.gov.au/dataset/ga/77772, and; the same three-class interval binning and colour scheme applied to the source point data in the Lu-Hf Isotopes - Summary Data layer (classification 2). 128.356727 -24.134164016647095 139.836727 -11.904164002361881 isotope:luhf_t2dm_grid image/png image/jpeg text/plain application/vnd.ogc.gml text/xml application/vnd.ogc.gml/3.1.1 text/xml text/html application/json EPSG:3857 EPSG:3857:0 0 0 0 0 EPSG:3857:1 1 1 1 1 EPSG:3857:2 2 2 3 3 EPSG:3857:3 4 4 6 7 EPSG:3857:4 8 9 13 14 EPSG:3857:5 17 18 27 28 EPSG:3857:6 34 36 54 56 EPSG:3857:7 68 72 109 113 EPSG:3857:8 136 145 219 227 EPSG:3857:9 273 291 438 454 EPSG:3857:10 546 582 877 909 EPSG:3857:11 1092 1165 1754 1819 EPSG:3857:12 2184 2331 3508 3639 EPSG:3857:13 4368 4662 7016 7278 EPSG:3857:14 8737 9324 14033 14556 EPSG:3857:15 17475 18648 28067 29112 EPSG:3857:16 34950 37297 56134 58224 EPSG:3857:17 69901 74594 112269 116448 EPSG:3857:18 139803 149189 224538 232897 EPSG:3857:19 279606 298379 449077 465795 EPSG:3857:20 559213 596759 898154 931591 EPSG:3857:21 1118427 1193519 1796308 1863183 EPSG:4326 EPSG:4326:0 0 0 1 1 EPSG:4326:1 1 1 3 3 EPSG:4326:2 2 2 6 7 EPSG:4326:3 4 5 13 14 EPSG:4326:4 9 10 27 28 EPSG:4326:5 18 20 54 56 EPSG:4326:6 36 40 109 113 EPSG:4326:7 72 81 219 227 EPSG:4326:8 144 162 438 454 EPSG:4326:9 289 324 877 909 EPSG:4326:10 579 649 1754 1819 EPSG:4326:11 1159 1298 3508 3639 EPSG:4326:12 2318 2597 7016 7278 EPSG:4326:13 4637 5194 14033 14556 EPSG:4326:14 9275 10388 28067 29112 EPSG:4326:15 18551 20777 56134 58224 EPSG:4326:16 37102 41554 112269 116448 EPSG:4326:17 74204 83109 224538 232897 EPSG:4326:18 148408 166219 449077 465795 EPSG:4326:19 296817 332439 898154 931591 EPSG:4326:20 593634 664879 1796308 1863183 EPSG:4326:21 1187269 1329759 3592616 3726367 Pb-Pb Isotopes - Pb207/Pb206 Grid (Regolith) December 2023 This is an interpolated grid of Pb-Pb isotope data (Pb207/Pb206) 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.
