 | | The Alps are largely formed from crystalline rocks (granites, gneisses, mica-schists, porphyries, etc.) but there are also sedimentary rocks (limestones, dolomites and sandstones) that are widespread in the eastern sector and the pre-Alpine belt. |
 | | This is the point at which it is possible to distinguish a high (gravel and sand) from a low (mainly mud and clay) plain, separated by a row of springs that have had an important influence in the development of the plain's agricultural economy (cultivation of the rice fields, water etc.). |
 | | As with the Alps so with the Apennines, three sectors can be distinguished: a northern one of largely sandstones, marls and clays, covering Liguria, Tuscany and Emilia; a central one essentially of limestones, covering Umbria-Marches and Latium-Abruzzo; and, finally, a southern one of mixed rock types, covering Campania, Basilicata and Calabria. |
