  abstract = {{I}t has been debated for decades whether rigid inclusions, such as porphyroclasts and porphyroblasts, do or do not rotate in a softer matrix during deformation. {E}xperiments and numerical simulations with viscous matrix rheologies show ongoing rotation of circular inclusions, whereas using {M}ohr-{C}oulomb plasticity results in nonrotation. {B}ecause the rocks in which inclusions are found normally undergo deformation by dislocation creep, we applied a full-field crystal plasticity approach to investigate the rotation behavior of rigid circular inclusions. {W}e show that the inclusion's rotation strongly depends on the anisotropy of the matrix minerals. {S}trongly anisotropic minerals will develop shear bands that reduce the rotation of inclusions. {I}nhibition of rotation can only occur after a significant amount of strain. {O}ur results may help to explain why geologic rigid objects often show evidence for rotation, but not necessarily in accordance with the viscous theory that is usually applied to these systems.},
