Calcrete - Fossil Soils
The Eastern End of Mun Sands - Sandy Haven Bay
As at Freshwater East , some of the Old Red Sandstone Boulders show signs of Calcretes.
In a process taking thousands of years , dissolved Calcium Salts are drawn to the surface by
evaporatation , becoming concentrated on soil particles , as the interstitial soil spaces are
filled, an impermeable crust is formed , creating irregular nodules.
Calcretes can also form by a concentration of calcium around plant roots .
