“…Until now, the máximum subsidence rate (-0.02 mm/yr) has been calculated at the Torre Santa Sabina site (Marsico et al, 2003). The subsidence rate calculated from MIS 5.5 to the present for the Apulian Tavoliere plain is comparable to those of the Trieste, Versilia and Sarno plains (respectively -0.21, -0.28 and -0.26 mm/yr), while it is quite distinct from those of the greatest Italian plain (Po plain), which are between -0.80 and -1 mm/yr (Ferranti et al, 2006). This first report of subsidence affecting the Apulian Tavoliere áreas from MIS 5.5 to the present proves that the Apulian Tavoliere Plain also behaves, from a tectonic point of view, like other Italian coastal plains; this allows us to modify the regional frame reported in Ferranti et al (2006), showing a slow to rapid uplift moving northward along the Adriatic coast (Fig.…”

“…MIS 5.2 is marked by land emersión, whereas no evidence of land emersión between MIS 5.5 and 5.3 has been found. VI) The finding of the buried C. caespitosa layer also allowed us to fill a gap in the data regarding the recent tectonic movements along the Adriatic coast (Ferranti et al, 2006): in fact, it proves that there has been a recent subsidence since MIS 5.5 in the coastal área of the Apulian Tavoliere plain.…”

“…In general, the data suggest that the Garganic Apulian foreland and the Amendola highland experienced an uplift, while the central-southern part of the study área, belonging to the Apulian Tavoliere plain, suffered a subsidence with rates increasing from north-northwest to south-southeast. In particular, the finding of the MIS 5.5 buried layer with C. caespitosa has allowed us to fill a gap in the data regarding the recent tectonic movements along the Adriatic coast (Ferranti et al, 2006). This feature proves that there has been a recent subsidence event since MIS 5.5 in the coastal área of the Apulian Tavoliere plain.…”

“…In this work, a MIS 7.3 highstand at -10 m has been carefully considered, as this is an intermedíate valué among those reported in Schellmann and Radtke (2004), Bintanja et al (2005) and Waelbroeck et al (2002). In addition, according to Lambeck et al (2004a) and Ferranti et al (2006), a máximum sedimentation depth of 2 m can be attributed to the lagoon bottom. It follows that among substages 7.3 and 5.5 there was a substantial stability, with an uplift of only 6 m ( + 0.06 mm/yr; Fig.…”

The geologic study of the Apulian Tavoliere plain (Apulia región, southern Italy) is extremely difficult due to the scarcity of outcrops and fauna that could be used for dating. The survey inprogressof the 1:50,000 scale geological sheetno. 409 "Zapponeta" (including the coastal zone of the Apulian Tavoliere) has prompted us to tackle this problem by using a large set of borehole data and the AAR dating method applied to ostracod shells, which are capable of colonizing all types of environment as long as there is water. This alternative approach has allowed us to recognise nine stratigraphic units or synthems and, for the first time in this área, to date them, and to find a correlation between them and the cycles of sea level variation. The recognised stratigraphic units are: the Coppa Nevigata sands (NEA; middle Pleistocene: MIS 17-16), argíüe subappennine unit (ASP; middle Pleistocene: MIS 15-13), the Coppa Nevigata synthem (NVI; middle Pleistocene: MIS 11), the Arriendóla subsynthem (MLMi; middle Pleistocene: MIS 11), an undifferentiated continental unit (UCI; middle Pleistocene: MIS 8-7), the Foggia synthem (TGF; middlelate Pleistocene: MIS 6), the Carapelle and Cervaro streams synthem (RPL; late Pleistocene: MIS 5-3), and the Inacquata farm synthem (NAQ; Holocene). Within the RPL unit, a buried Cladocora caespitosa bioherm referable to MIS 5.5, lacking in warm fauna, and in which the coral is embedded in clay has been found in some boreholes. This is the first finding of Tyrrhenian deposits with C. caespitosa along the Italian Adriatic coast; the presence of this coral in clayey sediments, a very uncommon occurrence, strengthens the hypothesis that the major fossil reefs grew in coastal waters that were characterised by alluvial inputs of fine sediments, higher turbidity, and higher temperature than today. In addition, on the basis of the current evidence, some consideration about the fauna of the MIS 5.5 layer allows us to hypothesise that the Adriatic Sea underwent a more modérate warming compared to that of the Ionian and Tyrrhenian seas. Instead, the finding in the NVI unit of a tropical lagoonal deposit with stromatolites referred to MIS 11 proves that the warming in this stage was undoubtedly greater than that of MIS 5.5. The MM4 borehole, which goes through the MIS 5 layers of the RPL unit, made it possible to recognise two marine phases during MIS 5: the first is referable to the MIS 5.5-5.3 interval, and the second to MIS 5.1. MIS 5.2 is marked by land emersión, whereas no evidence of land emersión between MIS 5.5 and 5.3 has been found. Also for the first time in this área, uplifting and subsiding áreas have been recognised and the vertical movements assessed. In general, the data suggest that the Garganic Apulian foreland and the Amendola highland experienced an uplift, while the central-southern part of the study área, belonging to the Apulian Tavoliere plain, suffered a subsidence with rates increasing from north-northwest to south-southeast. In particular, the finding of the MIS 5.5 bu...

Vertical GPS ground motion rates in the Euro‐Mediterranean region: New evidence of velocity gradients at different spatial scales along the Nubia‐Eurasia plate boundary

[1] We use 2.5 to 14 years long position time series from >800 continuous Global Positioning System (GPS) stations to study vertical deformation rates in the Euro-Mediterranean region. We estimate and remove common mode errors in position time series using a principal component analysis, obtaining a significant gain in the signal-to-noise ratio of the displacements data. Following the results of a maximum likelihood estimation analysis, which gives a mean spectral index~À0.7, we adopt a power law + white noise stochastic model in estimating the final vertical rates and find 95% of the velocities within ±2 mm/yr, with uncertainties from filtered time series~40% smaller than from the unfiltered ones. We highlight the presence of statistically significant velocity gradients where the stations density is higher. We find undulations of the vertical velocity field at different spatial scales both in tectonically active regions, like eastern Alps, Apennines, and eastern Mediterranean, and in regions characterized by a low or negligible tectonic activity, like central Iberia and western Alps. A correlation between smooth vertical velocities and topographic features is apparent in many sectors of the study area. Glacial isostatic adjustment and weathering processes do not completely explain the measured rates, and a combination of active tectonics and deep-seated geodynamic processes must be invoked. Excluding areas where localized processes are likely, or where subduction processes may be active, mantle dynamics is the most likely process, but regional mantle modeling is required for a better understanding.

Since the first discovery of ultrahigh pressure (UHP) rocks 30 years ago in the Western Alps, the mechanisms for exhumation of (U)HP terranes worldwide are still debated. In the western Mediterranean, the presently accepted model of synconvergent exhumation (e.g., the channel-flow model) is in conflict with parts of the geologic record. We synthesize regional geologic data and present alternative exhumation mechanisms that consider the role of divergence within subduction zones. These mechanisms, i.e., (i) the motion of the upper plate away from the trench and (ii) the rollback of the lower plate, are discussed in detail with particular reference to the Cenozoic Adria-Europe plate boundary, and along three different transects (Western Alps, Calabria-Sardinia, and Corsica-Northern Apennines). In the Western Alps, (U)HP rocks were exhumed from the greatest depth at the rear of the accretionary wedge during motion of the upper plate away from the trench. Exhumation was extremely fast, and associated with very low geothermal gradients. In Calabria, HP rocks were exhumed from shallower depths and at lower rates during rollback of the Adriatic plate, with repeated exhumation pulses progressively younging toward the foreland. Both mechanisms were active to create boundary divergence along the Corsica-Northern Apennines transect, where European southeastward subduction was progressively replaced along strike by Adriatic northwestward subduction. The tectonic scenario depicted for the Western Alps trench during Eocene exhumation of (U)HP rocks correlates well with present-day eastern Papua New Guinea, which is presented as a modern analog of the Paleogene Adria-Europe plate boundary.
