Abstract

Our understanding of fabric evolution in rocks and icemasses has advanced from simply measuring the c-axis. Sotoo have the methods available to extract crystallographicorientation data. Methods such as neutron diffraction (ND),electron backscattering diffraction (EBSD) can potentiallyprovide a higher density of information and data onadditional crystallographic axes. In addition, techniquesutilizing EBSD and automated optical fabric analysers(FA) have the advantage of producing spatially referenceddata with the ability to generate Achsenverteilungsanalyse(AVA) or axial distribution diagrams (Sander 1950). Sucha diagram, essentially a map of crystallographic orientationwithin a 2D slice from a sample, can help identify spatiallydistinct grains or groups of grains. In this contribution wewill illustrate and draw comparisons between the outputsbetween the three main techniques currently being used inthe structural geology community.
