Spatial characteristics of recycled and primordial reservoirs in the deep mantle

The dataset includes three data tables. The first table (Table S1) is a compilation of previously published geochemical data for global hotspots and relevant geophysical data extracted from published models. The second table (see "Newly Reported Data" tab) presents a new 3He/4He measurement for the San Felix Island. The third table (Table S3) is a compilation of published hotspot buoyancy fluxes for the hotspots examined in this study. In short, only the "Newly Reported Data" tab provides new data, while Tables S1 and S3 provide only previously published data (or data extracted from published global seismic models and buoyancy flux models). For Tables S1 and S3, which provide compilations of previously published data, the complete references for the data sources are provided.
