(a, b) Compressional brittle back structures (top-to-0° up) in Mandhani Formation schists and limestones at Location 8 (30.6802°N, 78.3497°E). (a) Width of photo c. 3 m. (b) Width of photo c. 2 m. (c) Top-to-75° up compressional brittle back structures in Rautgara Formation schistose quartzites, at Location 12 (30.597°N, 78.3191°E), near village of Barethi. Attitudes of Y- and P-planes: 165°/40°→255° (measured at the red arrow) and 160°/61°→250° (measured at the yellow arrow), respectively. (d) Top-to-0° up shears at Location 13 (30.5495°N, 78.3238°E) and incorporated in Group 2 in section 4 in the main text. In the inset diagrams, the stereo-plots of the poles of the corresponding Y- and P- planes are shown by red and yellow dots, respectively. Attitudes of Y- and P-planes: 64°/32°→154° (measured at the red arrow) and 85°/65°→175° (measured at the yellow arrow), respectively.
