A Review of the Spatiotemporal Evolution of the High Arctic Large Igneous Province, and a New U-Pb Age of a Mafic Sill Complex on Svalbard

Original data and compiled literature data presented in an Excel file to accompany the paper "A Review of the Spatiotemporal Evolution of the High Arctic Large Igneous Province, and a New U-Pb Age of a Mafic Sill Complex on Svalbard" by Sartell et al. (2025), published in Geochemistry, Geophysics, Geosystems in the Special Collection "Through the Arctic Lens: Progress in Understanding the Arctic Ocean, Margins and Landmasses". This file contains a compilation of all published geochronology of the High Arctic Large Igneous Province (HALIP), a compiled dataset of analytically and statistically reliable U-Pb and Ar-Ar ages from the HALIP based on criteria proposed in Sartell et al. (2025), original U-Pb baddeleyite isotopic dilution thermal ionization mass spectrometry (ID-TIMS) data from a mafic sill in Ekmanfjorden, Svalbard, and detailed information regarding the collected samples. References for the cited literature data can be found in the paper.
