Focal mechanisms of intraslab earthquakes: insights from pseudotachylytes in mantle units

This file contains all the experimental data, in datails, that are published in our JGR: Solid Earth paper. Our method resolves the seismic slip direction and slip sense and it provides promising results to investigate subduction tectonics. This method utilizes the kinematic information recorded in magnetic fabrics of fault pseudotachylytes. <br><br>Dataset includes the results of below measurements:1- Verwey Transition Temperature was measured on a Quantum Design Magnetic Properties Measurement System (MPMS) at the Institute for Rock Magnetism2- Thermomagnetic Experimens that were performed in the Paleomagnetism Laboratory at UT Dallas using an AGICO Kappabridge MFK1-A system interfaced with a CS-4 furnace3- Anisotropy of Magnetic Susceptibility (AMS) of mafgnetic fabric in pseudotachylytes were measured using an Agico (Brno, Czech Republic) Kappabridge 4-S in 450 A/m fields, at a frequency of 875 Hz.4- Magnetic Hysteresis and FORC measurements were performed on a Princeton Measurements Vibrating Sample Magnetometer (VSM) 3900-04 in fields up to 2 T. Dunlop plot of dataset is availabe in repository5- Frequency dependence of susceptibility was measured on a Quantum Design Magnetic Properties Measurement System (MPMS) at the Institute for Rock Magnetism<br>
