Geometry and kinematic evolution of the central sector of the Simbruino-Ernica catena, Lazio, central Apennines

The Simbruini-Ernici Mts. are a NW-SE striking carbonatic range bounded by the Latina Valley to the SW, Roveto Valley to the NE and partially overthrusted to the NW, by the Umbro-Sabine domain, along the Olevano-Antrodoco line. The stratigraphic framework of the range is characterized by the typical Latium-Abruzzi Mesozoic carbonate platform sequence, over 3000 meters thick, followed by the transgressive Calcari a briozoi e litotamni unit (Middle Miocene). In Upper Tortonian times, the area is involved in the Upper Miocene terrigenous units of Marne a Orbulina and flysch. In the study area, the whole Mesozoic sequence outcrops from Upper Triassic to Upper Cretaceous, locally overlain by the middle Miocene limestones. The results of the structural analysis performed in the central portion of the Simbruini-Ernici Range are presented and discussed together with other new data. -from English summary
