MECCANISMI DI ROTTURA FRAGILE ED EVOLUZIONE DEL FENOMENO CATACLASTICO NELLE ROCCE CARBONATICHE DELL'APPENNINO CENTRALE: SINTESI DELLE CONOSCENZE E PROGRAMMA DI RICERA

Abstract

This paper briefly outlines the geostructural issues ad­dressed by a research program developed within the frame­work of the CROP-11 Project (Deep crust seismic profile across the centrai Apennines). In particular, some characteris­tics of fault rocks and kinematic indicators on fault planes are discussed in the light of their possible contributi on to solve some of the many tectonic problems in the area. It is espe­cially stressed the importance of the fractal behavior of many tectonic phenomena for an improved interpretation of the major tectonic features. Relevant aspects of this research will be the design and operation of a fault zone database (espe­cially focused on geometries, lithologies involved, characters of fault surfaces and fault rocks) and the development of specific experimental and numerica! models.
