A multi-method approach (palaeothermal and thermochronological analyses; thermal modeling) is applied to reconstruct the exhumation history of the Altotiberina Fault (ATF), a representative example of crustal-scale active low-angle normal faulting in the Northern Apennines (Italy). Thermal maturity and thermochonological data yield similar burial h...

Shale gas is envisaged to contribute in the next future to the European energy mix in the perspective of lowering CO2 emissions. Poland is by far one of the most perspective countries in Europe. In the "Golden Belt", potential productive levels are Lower Paleozoic in age and the reliable assessment of their thermal maturity is crucial for evaluatin...

A new data set of temperature-dependent clay mineral parameters and vitrinite refl ectance of the Tuscan successions in the Northern Apennines (Italy) displays decreasing levels of thermal maturity from hinterland to foreland, and abrupt changes parallel to the strike of the chain which are structurally controlled by northeast-southwest–trending fa...

We report on an extensive paleomagnetic study (36 sites) of the Tuscan Nappe succession from the Northern Apennines Arc, aimed to reconstruct the tectonic evolution of the internal sector of this chain. We analyzed Eocene pelagic foreland ramp deposits (Scaglia Toscana Formation) and Oligocene–lower Miocene siliciclastic turbidites (Macigno and Fal...

Organic and inorganic paleothermal indicators (vitrinite reflectance‐ Ro%; illite content in mixed‐layer illite‐smectite‐ I% in I‐S) are routinely used to unravel the burial and tectonic evolution of fold‐and‐thrust belts by determining levels of thermal maturity of sedimentary successions and the amount of tectonic overburden currently eroded. How...

A reconstruction of the last 2,000 years BP of environmental and oceanographic changes on the western margin of Spitsbergen was performed using a multidisciplinary approach including the fossil assemblages of diatoms, planktic and benthic foraminifera and calcareous nannofossils and the use of geochemistry (X-ray fluorescence spectroscopy, X-ray di...

Reconstruction of geomagnetic field changes has a strong potential to complement geodynamo modeling and improve the understanding of Earth's core dynamics. Recent works based on geomagnetic measurements pointed out that over the last two decades the position of the north magnetic pole has been largely determined by the influence of two competing fl...

The Argentinean Andean region hosts a vast geothermal resource clustered by active magmatic and tectonic activity. One of the most studied geothermal areas is the Tuzgle-Tocomar geothermal system in Central Puna (NW Argentina). However, despite the existence of several studies since the 1970′s highlighting the geothermal potential of the area, only...

This paper presents a detailed geological map at the 1:20,000 scale of the Tocomar basin in the Central Puna (north-western Argentina), which extends over an area of about 80 km 2 and displays the spatial distribution of the Quaternary deposits and the structures that cover the Ordovician basement and the Tertiary sedimentary and volcanic units. Th...

Paleo-thermometers in sedimentary basins often drive to misleading thermal modelling when applied alone or only on potentially productive Paleozoic source rocks. Different paleo-thermal and thermo-chronological data have been used as constraints to model the Silurian to Cenozoic succession of a recently drilled well in the onshore portion of the Ba...

Reconstruction of Paleomagnetic Secular Variation (PSV) of the geomagnetic field is fundamental both to assess geodynamo models and to obtain age constraints for rocks, sediments and archaeological material. We present refined age-calibrated Holocene PSV and relative paleointensity (RPI) stack curves derived from Arctic marine sediments (Northweste...

Native and transplanted lichens were analyzed as bioaccumulators of airborne particulate matter (PM) in an eastern district of Rome, Italy, where frequent fraudulent fires are set to recover metals, mostly copper, from waste electrical and electronic equipment (WEEE). The presence of native lichens was scarce, due to the drought of spring-summer 20...

We present a paleomagnetic and rock magnetic data set from two long sediment cores collected from Bellsund and Isfjorden contourite drifts located on the eastern side of the Fram Strait (western Spitsbergen margin). The data set gave the opportunity to define the behavior of the past geomagnetic field at high latitude and to constrain the palaeocli...

High-resolution quantitative analyses of the planktonic foraminifera and calcareous nannofossils content have been carried out on IODP Leg 342, Hole U1406A (Northwest Atlantic Ocean) in the core interval 10H2–2H4, plotting the abundance distributions of the biostratigraphically and quantitatively most significant species. Qualitative analyses have...

The Contessa Section is a reference section for the early Miocene in the Mediterranean. Along this 36 m thick section 115 samples were collected and analysed for an integrated bio-magnetostratigraphic study through the Scaglia Cinerea and Bisciaro formations. Planktonic foraminifera were analysed semi-quantitatively, while calcareous nannofossils w...

TheMatuyama-Brunhes Boundary (MBB) recorded in the lacustrine sequence in the Sulmona basin (central Apennines, Italy) raised considerable scientific interest and has been the focus of various papers (Giaccio et al. 2013; Sagnotti et al. 2014; 2016). The interest comes from evidence for a very sharp geomagnetic polarity transition, that is radioiso...

Correlation of distinct stratigraphic sequences is often critical to characterize evolution of sedimentary basins, as well as for exploration of georesources and for paleoenvironmental and paleoclimatic reconstructions. Stratigraphic correlation is usually based on signal matching between two or multiple proxies’ records. Commonly, stratigraphers h...

Pyroclastic density currents (PDCs) can have devastating impacts on urban settlements, due to their dynamic pressure and high temperatures. Our degree of understanding of the interplay between these hot currents and the affected infrastructures is thus fundamental not only to implement our strategies for risk reduction, but also to better understan...

Anisotropy of magnetic susceptibility (AMS) has been applied to the study of shallow fault zones, although interpretation of the results requires establishing clear relationships between petrofabric and magnetic features, magnetic behaviour of fault rocks, and an extensive knowledge of P-T conditions. In this work, we demonstrate that magnetic meth...

Paleomagnetic and rock magnetic data were measured on glaciomarine silty-clay successions along an E-W sediment-core transect across the continental shelf and slope of the Kveithola paleo-ice stream system (south of Svalbard, north-western Barents Sea), representing a stratigraphic interval spanning the last deglaciation and the Holocene. The reco...

Major discontinuities in the Earth’s crust are expressed by faults that often cut across its whole thickness favoring, for example, the emplacement of magmas of mantelic origin. These long-lived faults are common in intra-plate environments and show multi-episodic activity that spans for hundred of million years and constitute first-order controls...

Thrusting at shallow depths often precludes analysis by means of structural indicators effective in other geological contexts (e.g., mylonites, sheath folds, shear bands). In this paper, a combination of techniques (including structural analysis, magnetic methods, as anisotropy of magnetic susceptibility and paleomagnetism, and paleothermometry) is...

This study presents new stratigraphic, structural and hydrogeological data on the Tocomar geothermal volcanic area (Puna plateau, Central Andes, NW Argentina), together with preliminary geochemical and magnetotelluric data.

During the past few decades, palaeomagnetism has been used as a powerful tool for constraining kinematic models of curved orogenic systems, because of its great potential in quantifying vertical axis rotations and in discriminating between primary and secondary (orocline s.l.) arcs. The Mediterranean area has represented an attractive region to app...

We report on results from anisotropy of magnetic susceptibility (AMS) analyses carried out on weakly deformed fine-grained sediments from the Northern Apennine orogenic system (Italy). We sampled 63 sites from pre-, syn- and post- orogenic sequences, which differ in age, composition, depositional environment, degrees of deformation and tectonic reg...

The 91.15 m thick St. Thomas section belongs to the Middle Globigerina Limestone, which is the intermediate member of the Globigerina Limestone Formation, and crops out along the eastern cliff of the Delimara Peninsula (the south-eastern part of Malta Island). The sedimentary record is composed of alternating calcareous mans and many limestones wit...

Pyroclastic density currents (PDCs) are very hazardous due to their impact on inhabited regions where they cause devastation and fatalities by exposure to mechanical impact, extreme heat and dusty gas. Estimation of PDC emplacement temperatures is fundamental to constrain numerical models and therefore volcanic hazard assessment. The emplacement te...

The faults chosen for this study belong to the Iberian Chain (Northeastern Iberian Plate) and include two kine-matically different kinds of structures (thrusts and strike-slip), with well-developed fault gouges several tens or hundreds of meters thick (Datos Fault System and Daroca Fault) and thinner clayey layers linked to thrust surfaces (Cameros...

In the last 30 years the origin of the Northern Apennines curvature and the amount and timing of CCW rotation of the Corsica-Sardinia block have been the focus of a large number of paleomagnetic investigations. In the Northern Apennines most of the paleomagnetic data were used to reconstruct the curved shape of the chain and most of the scientific...

In the Northern Apennines of Italy several paleothermal and low-T thermocronological studies have been performed in the last 20 years to investigate mainly the Tertiary burial and exhumation paths at shallow crustal levels of the main tectonic units that compose the fold-and-thrust belt. Nevertheless few of these studies address the topic of quanti...

Paleomagnetic and paleogeothermal analyses have been performed on the Meso-Cenozoic successions of the Tuscan Unit (Northern Apennines), with the aim of providing new constraints to understanding the evolution of this internal portion of the Apennines chain. The study of the tectono-sedimentary evolution of Tuscan Unit's formations can provide piec...
