The parent material of the soils of Northern Dobrudja is represented mainly (about 79 percent) by loamy eolian loess of wurmian age, and loess like deposits (eolian loess subsequently water transported and redeposit slopes of the residual prequaternary landforms and enriched in coarse fragments). The thickness of loess mantle varies from 10-25 m on the lower and less dissected areas, down to 1.5-3.0 m on the higher and strongly dissected parts of relief. The calcium carbonate content is of 7 to 35 percent. The other quaternary soil parent materials (sands, alluvia) have a minor participation (less than 4 percent). The soil parent materials originating by weathering of the prequaternary rocks are less widespread (17 percent) and from thin layers (0.5 m) of coarse material overlying bedrock. They consist mostly of weathering products of magmatic and metamorphic rocks (about 4 percent), sandstone (about 3 percent) and limestone (about 8 percent).
