Stress inversion results in (a) Region A and (b) Region B. (Left) The best directions of the principal stress (σ1, large circle; σ2, large triangle; σ3, large rectangle) and their 95% confidence regions (σ1, small circles; σ2, small triangles; σ3, small rectangles) are plotted in lower hemisphere projections. The numerals below the stereo-net show the azimuths and plunges of the best principal stress axes. The plunge is the angle of inclination measuring clockwise from horizontal plane. The misfit is shown as the ratio of the number of the inconsistent polarities to that of all of the polarities. (Right) Frequency distribution of R within the 95% confidence level.
