          What are the physical properties of limestone?
          Physical properties While not nearly as durable or hard as granite, limestone is relatively hard with a hardness of 3 to 4 on the scale on the Moh’s scale. It has nearly the same density as granite which makes it sometimes difficult to use in some building applications as slabs of limestone are not easy to move around.

          In the late Jurassic this area was an archipelago at the edge of the Tethys Sea. This included placid lagoons which had limited access to the open sea because they were surrounded by coral reefs. Water runoff from the land was low and, under the sun, evaporation was high. Salinity rose so high that the resulting brinecould n…
