We investigated the microstructures and geochemistry of pseudotachylytes found within the ophiolitic peridotites and gabbros from the Moncuni area (Lanzo Ultramafic Massif, Western Alps). The pseudotachylytes preserve dry glass and pristine microlites. The presence of garnet and the static development of eclogite-facies assemblages in local hydrated domains indicate that pseudotachylytes experienced subduction conditions of 600 °C and 2.1 GPa. Samples were investigated using optical and scanning electron microscopic imaging as well as electron backscatter diffraction, Raman and IR spectroscopy, single-crystal X-ray diffraction and microprobe analysis. Based on the analysis of the pseudotachylytes and associated wall-rocks, we suggest that the Moncuni body can be regarded as representative for the rheological behaviour during subduction of seismically active, dry, lithosphere. The data is organised in 8 folders termed Figure X, where X is the figure number in the primary publication. One folder is titled Supplements containing 5 subfolders equivalent to the supplementary material in the primary publication. Detailed information about the files and methods used is given in a readme file.
