“…Gran Sasso Range (GSR), where the LNGS is located, represents the northernmost front of the Abruzzi Apennines (Scisciani et al, 2002;Sani et al, 2004;Scrocca et al, 2005;Billi and Tiberti, 2009). Structural elements are represented by a complex system of overturned anticlines and related thrusts (Vezzani and Ghisetti, 1998;Ghisetti and Vezzani, 1999;Speranza et al, 2003;Calamita et al, 2006).…”

“…Ernici District consists of alkali basalts, latites, trachytes, and leucitites pyroclastic and lava vents (0.7-0.1 Ma [Civetta et al, 1981, and references therein]), located along NW-SE, NE-SW, and N-S fractures [Angelucci et al, 1974;Acocella et al, 1996]. The longest fissure ($20 km, Latina Valley Fissure), N-S trending, is associated with dextral faults (Figure 5d) [Acocella et al, 1996;Sani et al, 2004] and erupted the lowest 87 Sr/ 86 Sr ratios of the NW CampaniaLatium region [Civetta et al, 1981;Beccaluva et al, 1984;Turi et al, 1991]. Ponza island (Figure 3) mainly consists of lower Pleistocene submarine silica-rich hyaloclastites and rhyolitic dikes, emplaced along a NE-SW direction, consistently with the recognized fracture pattern [Carmassi et al, 1983;De Rita et al, 2001].…”

“…The NE side of the basin is characterized by a $4 km long NW-SE normal fault, controlling volcanic activity ( Figure 6) [Acocella et al, 1996]. Quaternary N-S dextral structures are also present, controlling part of the volcanic activity in the GDR Basin and the nearby Latina Valley (see section 3.2) [Acocella et al, 1996;Sani et al, 2004].…”

Transverse systems along the extensional Tyrrhenian margin of central Italy and their influence on volcanism

[1] The Tyrrhenian margin of central Italy has undergone Plio-Quaternary extension, developing NW-SE normal faults and NE-SW faults. The NE-SW faults decrease in frequency toward NE with the stretching factor b, becoming negligible for b < 1.3. Plio-Quaternary volcanoes, aligned NW-SE, formed at the intersection among NE-SW and NW-SE faults; fissure eruptions are mostly controlled by NE-SW faults. Structural field data show normal motions for 76% of NW-SE Quaternary faults and transtensive for 73% of NE-SW Quaternary faults. Analogue experiments simulating the NE-SW Tyrrhenian extension show that transverse transtensive faults form with differential extension Db > 0.21. These data suggest that the NE-SW transtensive structures are transfer faults of the NW-SE normal faults due to relevant differential extension (Db > 0.21) within a stretched crust (b > 1.3). The minor dip-slip and strikeslip components of the NE-SW and NW-SE faults, respectively, possibly result from the NW-SE extension due to the southeastward slab retreat beneath the Calabrian arc. The NE-SW and NW-SE extensions in the central southern Tyrrhenian Sea account for the composite kinematics of the NE-SW structures, which, in turn, exert a twofold role in controlling volcanism. Where their dip-slip component forms basins, the associated decompression induces magma accumulation (developing central volcanoes) at the intersection among NW-SE and NE-SW systems. Where transfer faults are mainly strike slip, their inferred subvertical attitude enhances their permeability to magma, accounting for the observed NE-SW fissure eruptions. Regional extension, forming NW-SE faults, enhances the overall generation and rise of magma along the margin, but NE-SW structures focus magma rise and emplacement at shallower levels.

“…After the main development of the central Apennine thrust and fold belt, crustal extension has affected the area of Rome since the late Messinian due to the development of the Tyrrhenian back-arc basin [Parotto and Praturlon 1975]; [Sani et al 2004]. Neo-autochthonous marine sedimentation occurred from the Pliocene to the early Pleistocene, which led to the deposition of the two transgressive cycles of Monte Vaticano and Monte Mario Formations [Bonadonna 1968, Conato et al 1980, Marra 1993, Marra and Rosa 1995; [Cosentino et al 2009].…”
