چکیده
The present study investigates the crystal preferred orientation (CPO) of quartz crystals in psammitic rocks to ascertain the deformation
mechanism using electron backscatter diffraction (EBSD) on quartz crystals from north of the Renvyle-Bofin Slide (RBS) near
Letterfrack in western Ireland. Complete crystallographic orientations were determined for several thousand individual quartz crystals
in psammite samples to provide a dataset for exploring the active deformation mechanism(s). Quartz crystallographic orientations are
plotted as pole figures and contour diagrams in <0001> and <11¯20> directions. Quartz-c-axis patterns show maxima in the Y axis of
the pole figure, which can be explained by the dominance of prism <a> gliding, indicating that dislocation creep was the dominant
deformation mechanism.
