During the Pleistocene, periods of loess deposition, weathering, and soil formation during interstadials alternated with periods of cryoplanation and deposition of solifiuction debris in valley sides and bottoms (Wood 1969; Leslie 1973).
In the alpine area of the Southern Carpathians, the alpine geomorphological landscape is dominated by glacial landforms (glacial cirques, throughs, moraines, erratics and roches moutone) and periglacial features (rockglaciers, talus cones and scree slopes, block fields, rock streams, cryoplanation terraces, patterned ground, solifluction forms etc.
