Quartz cement is shown to be syntaxial to the nearest host domain (grain or subgrain), both for
monogranular, polygranular, undeformed and deformed quartz. The quartz cement growth may have been initiated at different subgrain surfaces,
and preserving pre-depositional deformation structures. EBSD inverse pole figure imaging shows dauphine´ twins to be common in all samples,
both in quartz grains and quartz cement. The dauphine´ twins appear in grain-grain contacts and in cement-crystal boundaries, and commonly
crossing grainecement boundaries.
