I THRUSTS APPENNINICI ESTERNI NEL SETTORE FIRENZUOLE-BOCCA TRABARIA. EVOLUZIONE DEFORMATIVA ED IMPLICAZIONI STRUTTURALI

Abstract

The Northern Apennines thrust system consists of clas­tic foredeep deposits that have been progressively involved in thrusting towards the northeast from Oligocene to the Re­cent. The outcropping geological units, the Cervarola-Falte­rona unit (Early-Middle Miocene sandstones, shales and marl­stones), the Castel Guerrino unit (Middle Miocene sandstones and marlstones) and the Marnoso-Arenacea unit (Middle-Late Miocene marly sandstones), are progressively younger towards the foreland, implying that sedimentation and defor­mation developed together.
