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
