Evaluating quartz crystallographic preferred orientations and the role of deformation partitioning using EBSD and fabric analyser techniques

Quartz crystallographic preferred orientations (CPO) from three distinct orthogneisses using both the Electron Back Scatter Diffraction (EBSD) and Fabric Analyser (FA) techniques reveal a clear trend from basal and rhomb slip for high P–T conditions (670 ± 20 °C/9 kbar), rhomb and basal slip for m...

Zusammenfassung:	Quartz crystallographic preferred orientations (CPO) from three distinct orthogneisses using both the Electron Back Scatter Diffraction (EBSD) and Fabric Analyser (FA) techniques reveal a clear trend from basal and rhomb slip for high P–T conditions (670 ± 20 °C/9 kbar), rhomb and basal slip for medium P–T (590 ± 15 °C/6 kbar) and a dominance of prism slip for lower P–T conditions (
