    2021-10-15 · Fracturing of quartz grains, the main constituents of sandstone, requires forces that are unlikely to be reached during weathering. We hypothesize that the accelerated disintegration of the disconnected portions is caused by an easier dilation of the disconnected portion''s material, compared to the main rock mass.
