More than one hundred occurrences of stratified slope-waste deposits havebeen studied in an area of the Umbria-Marche Apennine (Central Italy).

Abstract

More than one hundred occurrences of stratified slope-waste deposits havebeen studied in an area of the Umbria-Marche Apennine (Central Italy). The area is characterized by mountains rising up to 1,700 m a.s.l. and underlain by mainly calcareous bedrock. The investigation took the structural and textural aspects pf the deposits into account with the intent of understanding the genesis. In the deposits open-work beds can be recognised, probably emplaced by gravity and slopewash on vegetation-free slope, together with beds rich in matrix emplaced by solifluction. The alternation of different bed types can be related to climatic variations over relatively long period in conditions substantially colder than the present.
