Abstract

Discrete methods of orientation distribution (ODF) analysis are applied to quartz and calcite rocks with trigonol crystal and triclinic sample symmetry. ODF’s are calculated from pole figures measured by neutron diffraction. A particular complication for quartz is the presence of overlapping peaks which can be separated with the WIMV or ADC algorithms based on diffraction intensity differences. Both methods provide similar solutions. Characteristic differences are discussed. By comparing ODF’s obtained from different data subsets (changing number and extent of pole figures) it is concluded that quantity and quality of data, as well as the texture type, have a crucial influence on resolution. It is demonstrated that discrete methods provide the possibility to obtain quantitative texture information from minimal experimental data.
