On the northern morphostructural boundary of the Apennine Peninsula

Abstract

Area of junction of the Northern Apennines and the peninsular part itself of Italy can be attributed to three areal units (megablocks) according to morphostructure. Geophysical data reveal the differences in deep structures of megablocks. The zone which delimits the North Apennines and two southern rnegablocks is identified as transversal morphostructural lineament and is considered to be morphostructural boundary between the peninsula and the continent. The peninsula shifts eastward along the boundary.
