Abstract
OLIVINE in rock-forming aggregates has a strong tendency during flow or deformation to develop a preferred orientation of its crystallographic axes. Turner1 describes a number of olivine fabrics developed under a variety of conditions. The pertinent examples, his figures numbers 7, 10 and 13, show fabrics for banded dunites in which the b crystallographic axis is strongly concentrated perpendicular to the banding, and figure 16, in which b is perpendicular to a plane of pronounced fissility. The (010) plane of olivine is the plane of the best cleavage and most probable glide plane for this mineral.
