The Jülich neutron diffractometer and data processing in rock texture investigations

The texture diffractometer SV7-b which is operated at the Forschungszentrum Jülich as a user and service instrument has been improved with respect to the efficiency of the position-sensitive detector system and to the variety of wavelengths available. Instrumental aspects of data collection and different methods of data processing for pole figure evaluation are discussed. Recent examples of texture investigations on geological materials are presented for quartz, hematite, hematite-quartz, orthopyroxen-quartz and anorthosite rocks.
