“…The interpretation of the givoni is controversial because few authors have described and interpreted these landforms (Bentivenga et al, , b; Boenzi et al, ). In addition, the internal structure described in this paper differs from those reported in the literature, in which only the seaward‐dipping beds are described.…”

“…Most authors have interpreted the terrace sequence along the Gulf of Taranto as having resulted from interactions between regional Quaternary land uplift and glacio‐eustatic sea‐level fluctuations. In contrast, Bentivenga, Coltorti, Prosser, and Tavarnelli (, b) interpreted the entire terrace sequence as a single middle Pleistocene terrace that was later offset by normal faults related to large‐scale gravitational processes, shifting the fragments to different elevations.…”

This paper presents a detailed geological and geomorphological analysis of the so‐called givoni (low‐relief, mainly gravelly landforms subparallel to the coastline) associated with the MIS 5 terrace in the northern Gulf of Taranto (southern Italy). These landforms can be interpreted as former beach ridges, swash/drift‐aligned spits, or swash/drift‐aligned barriers (BSBs); thus, givoni are palaeoshoreline indicators. In the study area, recognizing the classic landforms associated with marine terraces, that is, surfaces and scarps, is difficult, as the givoni are often associated and variably combined with surfaces and scarps. Thus, we reconstruct the formation and evolution processes of the MIS 5 marine terrace, including the formation of surfaces, scarps, and BSBs (and the resulting composite landforms), in an overall evolutionary framework based on eustatic oscillations. Then, we reconstruct a complete set of situations in which BSBs form on loose or semiconsolidated substrates in response to eustatic oscillations: (a) BSBs can form during a highstand of a warm stage on previously consolidated sediment; (b) BSBs may represent coastlines formed during sea‐level standstills in the context of a general regressive phase following the highstand peak that created a relict sea cliff; (c) BSBs may represent coastlines formed during a new relative highstand in a warm substage on previously unconsolidated deposits formed during the same stage; and (d) BSBs may be formed by a process similar to that of the previous case, except that the sea level stopped rising against a pre‐existing BSB.

Gas from mud volcanoes, dry mofettes, springs, and wells were sampled in a region of active tectonics and high seismicity in the southern Apennines (Italy), where there is a long history of disastrous earthquakes, with the latest (M s = 6.9) occurring in 1980. The fluids consist of a mixture of mantle-derived and crust-derived volatiles, with a low atmosphere-derived contribution, as identified by the He isotope signature and He/Ne ratio measurements. One year of monthly monitoring of the He concentrations and He isotopes revealed no seasonal modifications or variations induced by low seismicity. There are extraordinary high outputs of 4 He produced in the crust in the area (up to 2.5 × 10 28 atoms yr À1 ). These outputs cannot be solely due to the whole-rock production rate and a long-lasting diffusion degassing through the crust of the produced 4 He. This study explored the relation between the volume of fractured rock and the related release of He. The results support that crustal degassing can be controlled by tectonic events resulting in earthquakes. The high seismicity in this sector of the Apennines provides the conditions necessary for a massive release of He that has accumulated in the rock over a long time period. We identified that the assessed high crustal 4 He output can be attributed to an intense fracturing of a calculable volume of rock, which gives new constraints on the volume of rock involved in high-magnitude earthquakes in the region.

“…Terrace pediments are fundamentally erosional slope forms (Plakht et al, 2000), produced through one or more possible processes including fluvial (e.g., Veldkamp, 1992), glacial (e.g., Colman, 1976), periglacial (e.g., Czudek, 1995), and changing sea level (e.g., Cinque et al, 1995) origins. Terrace pediments have also been ascribed to basal weathering (detchplainsT) (e.g., Büdel, 1970) and geological processes such as slope displacement by normal faulting (e.g., Bentivenga et al, 2004). 0169-555X/$ -see front matter D 2004 Elsevier B.V.
