The Barga Basin (Tuscany): A record of Plio-Pleistocene mountain building of the Northern Apennines, Italy

The 2013 Lunigiana (Central Italy) earthquake: Seismic source analysis from DInSAR and seismological data, and geodynamical implications for the northern Apennines

“…Mosca F. Continental deposits: a = alluvial deposits (latest Pleistocene-Holocene); ta = terraced alluvial deposits and fanglomerates (middle-late Pleistocene); PQ = clays, sands, and conglomerates of lacustrine and alluvial environment (early Pliocene (Ruscinian)-to early Pleistocene (late Villafranchian)).

Speleogenesis in highly geodynamic contexts: The quaternary evolution of Monte Corchia multi-level karst system (Alpi Apuane, Italy)

“…An extensive tectonic phase caused uplift of the massif along fault systems with NW-SE and NE-SW strike (Carmignani and Kligfield, 1990). This phase migrated from SW to NE with the formation of the coastal basins first, which began in the Late Miocene, and successively the formation of the intermontane basins (Serchio valley) during the Middle-Late Pliocene (Bartolini, 2003;Coltorti et al, 2008).…”

“…The strong uplift stage of the Apuane massif that occurred in the Early Pleistocene (Bartolini, 2003;Coltorti et al, 2008) was probably the main cause of the progressive destruction of the surface basin that fed this important cave level. Allogenic recharge was firstly deviated through underground pathways towards the coastal Versilian basin (SW), and successively towards the Serchio basin (NE) by the headward capture of the Turrite Secca stream, a tributary of Serchio River.…”

Surface and subsurface drainage evolution of the Corfino and Soraggio karst areas (Tuscany, Italy)

“…As already suggested for t�e Barga depositional complex, we can refer to a simple model w�ere fluvial deposition occurred mainly during cold stages and incision during warm stages (Coltorti et al 2008). In suc� conditions, t�e discrete distribution of paleo-p�reatic passages, w�ic� are found in t�e two major valleys (Soraggio and Fiume canyons) on a vertical range of a few �undred meters, suggests t�at t�e different stages are t�e middle-term responses to climatic c�anges, t�at is, to t�e alternation of cold and warm periods.…”

“…Beginning from t�e Early Pleistocene, extensional tectonics partially dismantled t�is structure as a result of t�e uplift of t�e main Apennine c�ain and t�e tectonic collapse of Serc�io Basin (Puccinelli et al 1987;Bartolini 2003;Coltorti et al 2008 and references t�erein). Major faults �ave Nw-SE strikes and are part of t�e step listric system bounding t�e NE flank of t�e Serc�io River Basin (Dallan et al 1991).…”
