Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from shale by its lack of fissility (parallel layering). The term mudstone is also used to describe carbonate rocks (limestone or dolomite) that are composed predominantly of carbonate mud. However, in m… WebThe calculated bearing capacities and the subgrade reaction of the sandstone and shale lithologies are shown in Table 1. The ultimate bearing capacity of the sand ranges from 3141.755 to 5593.447 kN m -3 with an average of 4367.601 kN m -3 while that of the shale ranges between 2487.786 and 6335.588 kN m -3 with an average of 4411.687 kN m -3. have we found evidence of life on mars
