Microstructural Electron Backscattered Diffraction data from experiments designed to test whether olivine grain boundaries in the mantle are water enriched (NERC Grant NE/M000060/1)
Electron backscatter diffraction was used to quantify grain boundary misorientations in experimental samples doped with deuterium-enriched water. The same samples were subsequently studied with nanoSIMS to look for boundary enrichment of D2O. Grain boundary misorientation data were collected using EBSD to test the possibility of misorientation angle dependence on measured D2O concentrations. No clear misorientation dependence was observed. Folders names include the name of the PDRA who collected the data. Data are images, text files (ctf), and other file formats that can be opened using Oxford Instruments EBSD software. Supporting EDS files are available on request

Data Quality
Mixtures of olivine (80 wt.%) and orthopyroxene (20 wt.%) powder were pressed into capsules with 20 μl deuterium oxide. The capsules were sealed and heated to 1000-1300 °C under confining pressures of 300 MPa-2 GPa at the University of Manchester. Post-experiment the samples were polished and carbon coated before electron backscatter diffraction data was collected on an SEM at the University of Liverpool.
