(a, b) Compressional back structures in Blaini Formation slates and phyllites. (a) Top-to-35° up brittle shear at Location 25 (30.4297°N, 78.2362°E). Attitudes of Y- and P-planes: 119°/45°→209° (measured at the red arrow) and 124°/71°→214° (measured at the green arrow), respectively. In the inset diagrams, the stereo-plots of the poles of the corresponding Y- and P- planes are shown by red and green dots, respectively. (b) Top-to-35° up shear at Location 25 (30.4297°N, 78.2362°E). (c) Compressional brittle back structures in Blaini Formation slates and phyllites. Top-to-0° up brittle shear at Location 26. Y-plane attitude: 145°/55°→235° (measured at the red arrow; stereo-plot of pole in the inset). (d) Compressional brittle back structures in Krol Formation limestone. Top-to-0° up shear at Location 29 (30.4459°N, 78.1619°E).
