The residual stress in a quartz vein from a metamorphic province is evaluated by an X-ray diffraction technique. Diffraction analyses at multiple incident angles yield residual stress magnitudes for the specified directions on the plane parallel to the sample surface. Residual stress formation in the vein is found to be determined by the platy geometry with respect to the host rock. The results indicate a compressive residual stress of -15 to -20 MPa parallel to the long axis of the vein. The compressive stress magnitude parallel to the quartz vein is found to increase with sample temperature, indicating that the quartz vein has a greater thermal expansion coefficient than that of the host rock. A two-dimensional model explaining residual stress formation in the vein in response to tectonic exhumation is proposed, and the paleostress magnitude at the time of vein formation is estimated from the residual stress magnitude and fluid inclusion microthermometric data. The quartz vein is concluded to have formed under a horizontal compressive stress of 550-660 MPa in the direction parallel to the long axis of the vein.
