Abstract

The outer zones of the central Apennines are charac- terized by arcuate thrusts and related NE-verging folds that affect at least 2000 m thick Mesozoic-Neogene sedi- mentary succession (LAVECCHIA, 1981; GHISETTI & VEZ- ZANI, 1990). The base of the succession is represented by a massive 800 m thick carbonate platform unit of Early Liassic age (Calcare Massiccio Fm.), that grades upwards into well-bedded pelagic carbonates, marls and silicicla- stics. The Jurassic portion of the succession displays thickness and facies variations, that are controlled by syn- sedimentary normal faults: these dismembered the Early Liassic carbonate platform into differently subsiding sea- mounts and troughs. The subsequent onset of Neogene orogenic deformation was responsible for the contraction of the sedimentary succession. A detailed analysis of some anticlines reveals the oc- currence of high-angle thrusts within the Calcare Massic- cio Fm., whose displacements are accommodated by fol- ding within the overlying pelagic succession.
