title: Supplementary data to "Destruction and regrowth of lithospheric mantle beneath large igneous provinces"

description: Database files to accompany "<em>Destruction and regrowth of lithospheric mantle beneath large igneous provinces</em>", By Stephenson et al. (2023). The article can be accessed by following this permanent link. The primary resources in this database are (i) estimates of melt equilibration pressure and temperature calculated using the scheme of McNab & Ball (2023); (ii) a database of lithospheric thickness estimates beneath modern intraplate magmatic provinces using geochemical and seismological techniques; (iii) a database of the outlines and ages of large igneous provinces, substantially updated from Coffin & Eldholm (1994), and Coffin et al. (2006); (iv) a database of large igneous province eruption centres; and (v) a document of references used to build these databases. Files are numbered as in the Supplementary Information of the paper. Please see below for more details. <strong>Data S1</strong>. A database of global geochemical compositions of mafic intraplate magmatic rocks compiled by Ball et al (2021), and corresponding estimates of melt equilibration pressure and temperature P<sub>eq</sub> and T<sub>eq</sub>, respectively; this study). Note that authors should cite Ball et al. (2021) in reference to the global geochemical database. They should cite Stephenson et al (2023) in reference to the global equilibration pressure and temperature estimates, in which case they should also cite McNab & Ball (2023), whose software was used to calculate P<sub>eq</sub> and T<sub>eq</sub>. <strong>Data S2</strong>. A spreadsheet containing modern-day lithospheric thickness estimates beneath modern intraplate provinces. For complete references to geochemical analyses contained in this database, please see Ball et al (2021). The database includes lithospheric thickness estimates obtained by exploiting melt equilibration pressure and temperature (this study); by inverse modelling of rare earth element compositions (Ball et al., 2021); and from the lithospheric thickness model of Hoggard et al. (2020), which is based upon the tomographic model of Schaeffer & Lebedev (2013). <strong>Data S3</strong> & <strong>S4</strong>. A database containing outlines of magmatic provinces dating back to 750 Ma, including a directory (Data_S3.zip) containing the unfiltered database shape files (lips.shp, lips.shx, lips.dbf, lips.cpg). This directory also contains the same data in a multisegment text file for plotting in the Generic Mapping Tools (polys_ID_age_unfiltered.dat) in which each polygon is separated by '&gt;' where the header indicates polygon ID and time since eruption. And a database filtered for final magmatic event in a given location (Data_S4.dat), where each polygon header also contains '&gt;' ID age polygon_area'. See the paper for methodological details. <strong>Data S5</strong>. A database of located LIP eruption centres. <strong>Data S6</strong>. A pdf document of references. The document includes references used to update locations and ages of the large igneous province database of Coffin et al. (2006); references for existing lithospheric thickness models used test our observed LAB depth as a function of time relationship; and references used to locate the eruption centres of mantle plumes (i.e. Data S5; this study).
