There is given description of the preconditions of mechanic weathering processes occuring in the oases in Antarctica, using numerous temperature measurements made on the solid rock as well as measurements of the temperature and water content
In Antarctica, many of the rift grabens have been preserved by covering ice. Some have been sufficiently well studied by geophysical methods to be recognised at three different crustal levels i. e., the bedrock surface, the surface of solid crust
