description: This repository contains the supplementary materials for "Underplated melts control sulfide segregation at the continental crust-mantle transition". Contained within:Supplementary figuresSupplementary Table 1. Nomenclature of the samples collected from the Balmuccia mantle peridotites, Contact Series sequence, and Mafic Complex with the corresponding numbers of thin-sections and whole-rock analyses number used in this study.Suplementary Table 2. Bulk-rock chemical composition of the investigated samples.Supplementary Table 3. Petrographic and textural characteristics of sulfides.Supplementary Table 4. Average major and trace element composition of pentlandites from Balmuccia mantle peridotites and Contact Series sequence.Supplementary Table 5. Average major and trace element composition of pyrrhotites from Balmuccia mantle peridotites and Contact Series sequence.Supplementary Table 6. Average major and trace element composition of chalcopyrites from Balmuccia mantle peridotites and Contact Series sequence.Supplementary Table 7. Average major and trace element composition of pyrites from Balmuccia mantle peridotites and Contact Series sequence.Supplementary Table 8. Average major element contents (wt%) and their molar ratios in sulfide phases.Supplementary Table 9. Bulk sulfur geochemistry of the Contact Series sequence of the Balmuccia peridotite massif.Supplementary Table 10. Detection limits and uncertainties of the whole-rock major element measurements determined using X-ray Fluorescence at the Federal Institute for Geosciences and Natural Resources (BGR), Hannover, Germany.Supplementary Table 11. Detection limits and uncertainties for selected elements of the whole-rock trace element measurements at the Activation Laboratories Ltd., Canada.Supplementary Table 12. Modal composition of host silicate rocks.Supplementary Table 13. Detection limit (ppm), accuracies (%), and precisions (rel.%) of EPMA measurements for sulfides.Supplementary Table 14. The accuracy and precision of the LA-ICP-MS measurements calculated based on Se and Rh contained in both NIST 610 and PGE-A standards. The normalization values are adapted from Lorand and Alard (2001).Supplementary Table 15. Average detection limits and sample errors (ppm) of LA-ICPMS measurements for pentlandites from Balmuccia mantle peridotites and Contact Series sequence.Supplementary Table 16. Average detection limits and sample errors (ppm) of LA-ICPMS measurements for pyrrhotites from Balmuccia mantle peridotites and Contact Series sequence.Supplementary Table 17. Average detection limits and sample errors (ppm) of LA-ICPMS measurements for chalcopyrites from Balmuccia mantle peridotites and Contact Series sequence.Supplementary Table 18. Average detection limits and sample errors (ppm) of LA-ICPMS measurements for pyrites from Balmuccia mantle peridotites and Contact Series sequence.In addition to supplementary materials, associated with the submission to Communications Earth &amp; Environment, this repository contains raw data collected during electron microprobe measurements (EPMA) and laser ablation coupled to inductively coupled plasma mass spectrometry (LA-ICPMS) measurements. The original files of LA-ICPMS measurements are packed into one folder entitled "LA_ICPMS_raw data" and grouped into analytical sessions (each session per one thin-section). The LA-ICPMS results are associated with EPMA results, as the same sulfide grains have been analyzed by these two methods. <br>
