This data package contains the reconstructed scans presented in the paper of Beyer et al. 2024, Sulfide melt wetting properties in Earth's mantle: New constraints from combined 2D and 3D imaging. The data package is divided in five folders, each representing one sample.
The goal of the study was to gain a better understanding of how polymineralic silicate rocks and pressure influence the mobility of sulfide melts in the Earth's deeper upper mantle. A series of high-pressure experiments was conducted between 6 and 13 GPa, with temperatures above the liquidus of FeNiS and a metal-to-S ratio of approximately 1. By combining dihedral angles measured on 2D sections of samples with 3D tomography, we found that under conditions typical of the uppermost transition zone, sulfide melts have the potential to form an interconnected liquid network within a majoritic garnet and omphacite matrix. Experiments with sulfide melt and a matrix mainly consisting of olivine confirmed previous results that sulphide melt blebs are isolated.
Every folder contains a series of .tiff files making up a 3D volume and a text file that describes either the scanning or reconstruction parameters.
The data is provided in five subfolders. Detailed information about the files in these subfolders is given in the explanatory file ReadMe_Wepros.txt. Contact person is Christopher Beyer - christopher.c.beyer@rub.de
