The Alps continue fairly smoothly into the following related Alpine mountain ranges: the Apennines to the southwest, the Dinarides to the southeast and the Carpathians to the northeast. In the east the Alps are bounded by the Viennese Basin and the Pannonian Basin, where east–west stretching of the crust takes place.
The geology of Italy includes mountain ranges such as the Alps and the Apennines formed from the uplift of igneous and primarily marine sedimentary rocks all formed since the Paleozoic. [1] Some active volcanoes are located in Insular Italy .
At places throughout the Alps the European basement was, after being detached of its cover rocks, tectonically uplifted in a late stage of the orogeny. Thus the "external massives" were formed, places where the Hercynian basement rock crops out in large anticlinoria at the southern (or in France eastern) side of the Helvetic zone.
It is not possible to define the Alps geologically, since the same orogenous events that created the Alps also created neighbouring ranges such as the Carpathians (see also geology of the Alps). The Alps are a distinct physiographic province of the larger Alpine System physiographic division, but the Alps are composed of three distinct ...

The formation of the Alps started 135 million years ago at a strike-slip fault between the Penninic and Tethys Ocean. The Northern Calcareous Alps and Gurktal Alps formed as an orogenic wedge as sedimentary rocks were torn off basement rock that was subducted back into the mantle. The crust of the Penninic Ocean subducted around 85 million ...
The Helvetic nappes are thrust over the Infrahelvetic complex and the external massifs of the Alps (like the Aarmassif or Mont Blanc Massif). In Switzerland, Germany and Austria they are also thrust over the Molasse basin of the Alpine foreland. In turn, the Helvetic nappes were overthrust by the Penninic nappes from the south.
