LA MORFOGENESI GRAVITATIVA NEL VERSANTE ADRIATICO MARCHIGIANO

Abstract

This paper presents a synthesis of investigations carried out over thirty years in the Marche region (centrai Italy), with the pur­pose of pointing out both genetic factors of socia! impact of gravi­tational movements. The main genetic factors are the following: a) widespread outcropping of marly-clayey formations; b) altemations of stiff and soft lythotypes; c) occurrence of stratigraphic and tectonic discon­tinuities in the rock mass; 4) high relief due extensional tectonics (fault slopes) and deep valley incision induced by Quaternary uplift; 5) occurrence of thick eluvial-colluvial deposits on slopes.
