Orientation Distributions of Low Symmetry Polyphase Materials Using Neutron Diffraction Data: Application to a Rock Composed of Quartz, Biotite and Feldspar

The crystallographic texture of the three main constituting phases of a granodioritic rock have been determined quantitatively, using neutron diffraction with a position sensitive detector. Intensities deconvoluted from the full profiles were used in the orientation distribution refinements using the WlMV algorithm. Satisfactory results were obtained for the three phases.
