Notes: Descriptive features, size (thickness) of the structure in digital image and 2-D X-ray image, lithologic composition, degree of deformation, and estimated difference in directions of digital and X-ray images are shown. CT = computed tomography. SST = sandstone, SLST = siltstone, CST = claystone, lam = lamination. ? = unknown.
