If the quantity of water increases further it reaches the liquid limit at which clay freely outflows . These limits are called Atterberg limits . The impermeability of clay to water renders it geomorphologically quite important. MARL Fine-grained formation soft loose or friable. A Cyclades-Greece by Th. Godelitsas mixture of 35 clay 65 calcite. Its main feature is plasticity deriving from its content of clay 35 . LIMESTONE Rock that contains more than 90 CaCO3. The rest of the material that comprises it may be argillaceous ferric or magnesitic. Limestones are distinguished according to their origin in rocks of a. detrital b. chemical c. organic origin. Limestones weather and break up more easily than other rocks. Rain water through chemical decomposition solution causes karstification thus creating various landforms such as caves dolines poljes and uvalas. MOLASSE Term generally referring to a formation that consists of terrigenous material provided by the mountains weathering during orogenesis and deposited within the foretrench of the orogenetic arc. Its cohesiveness varies from low to very high. It is a mixture of sandstones conglomerates and silts by deposition of fresh or salt waters. Cartographically the molasse is depicted either by its constitutive elements or in a combination of a neutral colour lineage on an also neutral colour basis. Attica-Greece by Th. Godelitsas 190 Topography Lithology And Tectonics SOIL PROFILES Soil sections defined according to the rules of pedology. These profile-sections are registered in stations and are represented on maps by a cross accompanied by the depth indication in centimetres. TRAVERTINE lll l l A calcite deposit. It may 44T t--44 be located at the outlet III I 11 ILB of a karst spring on the borders of a waterstream or on the brinks of a waterfall. It originates from the chemical settling of calcium carbonate in .
