The volume texture of a naturally deformed quartzite from the
Kaoko belt, North-West Namibia, has been analysed by both
universal stage microscopy and neutron diffraction. Universal
stage microscopy is restricted to the determination of the base
pinacoid preferred orientation in quartzite. For a more complete
description of the texture, the orientations of additional crystal
planes, such as first and second order prisms as well as positive
and negative rhombs, must be known. Neutron methods allow the
evaluation of pole figures of all Bragg reflecting planes, of
which those of the first order prisms being considered to be the
most active slip planes, are of particular interest. Drawbacks of
neutron diffraction, i.e. the faking of an eventually absent
inversion centre and lack of resolution, can be overcome by pole
figure inversion and subsequent calculation of desired pole
figures. Both, universal stage microscopy and neutron diffraction
yield well comparable results, of course only with respect to the
pole figure of the c-axis.
