Abstract

In the Piedmont plain of NW Italy the Ivrea Morainic Amphitheatre (IMA) is a remarkable evidence of the Quaternary glaciations. It consists of a wide (505 km2) complex of lateral moraines (i.e. the Serra d’Ivrea), end moraines and kame terraces, encircling a 200 km2 wide flat internal depression above which a subglacially moulded rocky hills (the Colli d’Ivrea) elevates. The glacigenic succession ranges from the end of the Early Pleistocene (dated on palaeomagnetic basis) to the end of the Late Pleistocene (14C radiometric and 10Be exposure ages) (about 900–20 ky BP). The IMA has recently been parted into ten stratigraphical units, potentially correlable to the whole sequence of the main Quaternary glaciations recorded by the marine oxygen isotope stratigraphy. Natural (glacigenic deposits and forms) and archaeological (i.e. the Roman gold mines) features make the IMA a very interesting topic for a multidisciplinary research with educational, cultural and tourist purposes. Some recent and present activities for the land promoting are presented. A candidature to the UNESCO global geopark network is considered as a suitable and ambitious goal.
