On the method of active slip system detection in olivine porphyroclasts by EBSD

Abstract

The paper examines the sequence of determining the slip system in olivine porphyroclasts of mantle tectonites using the electron backscatter diffraction (EBSD) method. Determination of the orientations of the main crystallographic axes [100], [010], [001], the boundaries of kink bands and rotation axes is carried out automatically using the HKL Channel 5 or MTEX programs. The paper provides an example of such an analysis and shows that the study of porphyroclasts is an important clarifying method that complements statistical pole figure diagrams.
