Abstract
The authors have carried out an investigation that led to the production of a geomorphological map and its related explanatory notes. The present physionomy of the valley, mainly consisting of intrusive magmatic lithotypes, is related to various morphogenetic agents: those that acted for a longer time and more deeply are the glacial and periglacial ones. Typical erosional and depositional glacial forms characterize the middle and high valley. Morphological, stratigraphical and textural observations regarding. the weathered state of the deposits and the degree of lichenization, the various morainic deposits have been tentatively differentiated. The moraines from the last century are particulary abundant and thickly developed; in some places they cover deposits probably "ascribable to older stages of the «small glaciation». Also the moraines ascribable to the late-glacial stages are widely represented. Landforms related to periglacial environments such as rockglaciers, protalus rampart, etc., have been recognized. Particular landforms related to gravity and favoured by the metamorphic- type substratum are recognizable in the lower valley.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
