Electron backscatter diffraction data and sample analysis from the Nusfjord Shear Zone, Lofoten, Norway (NERC Grant NE/P001548/1)
Field and microstructural analysis of pseudotachylytes formed at lower crustal depths and now lying exposed in the Flakstadøy Anorthosite, Lofoten, Norway. Electron backscatter diffraction (EBSD) analysis : 10 EBSD datasets (cpr files) - unfiltered. These characterise deformation in pyroxenes spatially associated with pseudotachylyte faults in the Nusfjord anorthosite. Grain size analysis - backscattered electron (BSE) images and processed equivalents (segmented manually or with ImageJ software) of fragmented orthopyroxene for grain size analysis. Results are processed in the spreadsheet 'Grain size distributions for fragmented OPX'. Samples involved: LC1724 and N22 Grain growth modelling - spreadsheet calculating grain growth rates for orthopyroxene in samples LC1724 and N22 Strain analysis - used to estimate strain via clast analysis of mylonitised pseudotachylyte, sample 269c

Data Quality
EBSD data and BSE images: acquired from polished sections of the sampled pseudotachylytes at the Electron Microscopy Centre, Unversity of Plymouth using JEOL 7001 FEG-SEM (Nordlys Nano detector) and a JEOL 6610 low vacuum SEM (Nprdlys Max detector). Working distances, step sizes and accelerating voltages are contained within individual .cpr files. Grain growth modelling uses the empirical growth laws sourced from: Skemer, P., & Karato, S. (2007). Effects of solute segregation on the grain-growth kinetics of orthopyroxene with implications for the deformation of the upper mantle. Physics of the Earth and Planetary Interiors, 164(3), 186–196. https://doi.org/https://doi.org/10.1016/j.pepi.2007.06.011
