Magnetic resonance images of sandstone samples after different chemical solution erosion and freeze-thaw cycles: (a) images of sandstone samples under acidic solution (from left to right: freeze-thaw cycles are 0, 15, 30, 45, and 60, respectively); (b) images of sandstone samples under neutral solution (from left to right: freeze-thaw cycles are 0, 15, 30, 45, and 60, respectively); (c) images of sandstone samples under alkaline solution (from left to right: freeze-thaw cycles are 0, 15, 30, 45, and 60, respectively).
