An X-ray fabric analysis of quartz grains from the Sambagawa crystalline schist, Japan, whose c-axis fabric (optically measured) was regarded as corresponding to an ultimate steady-state pattern of preferred orientation of c-axes developed by the approximately non-rotational two-dimensional strain under the Sambagawa metamorphicconditions, has been made by a texture goniometer for reflection. It has been clarified that  and  directions are preferably oriented in the plane of the longest and shortest principal axes of the strain ellipsoid of mean strain of the system concerned and at the angles of ca. 35° and ca. 17° to the shortest principal axis respectively.
