TL;DR: In northwestern Anatolia two magmatic episodes are distinguished as mentioned in this paper : the Oligocene-Early Miocene and the Late Miocene-Pliocene, and they are associated with hypabyssal and volcanic rocks.

TL;DR: In this paper, the average regional and local stress fields responsible for fault development were determined using slip indicators preserved on the fault planes, using crosscutting relationships between different faults, sub-basin succession, morphotectonic features and overprinting criteria between faults and sediments.

TL;DR: In the field of metamorphic petrology, this paper developed methods to unravel the depth, thermal, temporal and deformational history of orogens using detailed observations at map, hand sample and thin-section scales in combination with elemental and isotope data, and using inverse and forward modelling.

TL;DR: The precursory nature of radon and helium anomalies is a strong indicator of the physical basis of earthquake prediction and a preliminary test for the proposed conceptual helium/radon ratio model.

TL;DR: In this article, it is shown that during the Late Heavy Bombardment (LHB) period, as preserved on the Moon, the terrestrial upper mantle-crust system was dominated by interactions between internal mantle processes and extraterrestrial impacts, and that following this period, the impact flux decreased by two orders of magnitude, from 4-9×10 −13 km −2 year −1 to 3.8-6.3×10−15 km −1 (for asteroids Dc >=18 km).

TL;DR: The origin of eclogite remains an enigma, despite of great progress in our knowledge of this rock as discussed by the authors, and it has been a matter of considerable interest during the last two decades, especially since the discovery of ultra-high-pressure coesite-bearing rocks in the crust has drastically changed geologists' ideas concerning the limits of ECLogite-facies crustal metamorphism.

TL;DR: Casterano et al. as mentioned in this paper presented a consistent model, which explains the mechanisms of unrest phenomena at Campi Flegrei (Italy), both at short-term (years) and at secular scales.

TL;DR: In this article, gravity measurements at close spacing (1-2 km) along three profiles (∼550 km each), starting from west coast of India upto the eastern margin of the Deccan Volcanic Province (DVP), are carried out to understand the subsurface density structures and tectonics of the region.

TL;DR: In this paper, the authors used the Pb/Pb single zircon dating technique to determine the ages of granitoid intrusives and orthogneisses from the mid-German crystalline rise (MGCR).

TL;DR: In this article, three different approaches are taken: (1) collision where one ‘continental plate’ is pushed against another across a zone of weakness; (2) gravitational instability of a lithospheric mantle root leading to delamination, slab break-off and crustal root reduction; (3) melting in the lower part of a crustal orogenic root.

TL;DR: A review of two centuries of tectonic interpretations of the Alps can be found in this paper, from the early fixistic tenets emphasizing vertical movements to the impact of the new global tectonics, through the epos of the nappe theory.

TL;DR: Tron et al. as mentioned in this paper performed a series of centrifuge analogue experiments to model the mechanics of continental oblique extension in the presence of underplated magma at the base of the continental crust.

TL;DR: Kaila et al. as mentioned in this paper re-examine the crustal structure of the Western Dharwar Craton (WDC) by reprocessing the data of three major shot points.

TL;DR: The NNE-trending Hunan-Jiangxi strike-slip fault system (HJSFS) as discussed by the authors comprises three primary faults (the Anhua-Chengbu fault, the Chalin-Chenxian fault, and the Ganjiang fault) with associated NE- and NW-tending secondary faults.

TL;DR: In this paper, three-layer feed-forward neural network models were constructed to analyse earthquake occurrences to predict the origin times of large (M⩾6.0) earthquakes.

TL;DR: In this article, the authors discussed the rheology of the mantle based on theoretical and experimental rate equations for steady state creep and compared with results from geophysical models and showed that the upper mantle is likely to show non-Newtonian rheological properties for average grain sizes larger than 0.1 mm as an order of magnitude.

TL;DR: The first roughly scaled experiments were performed by Sir James Hall about two centuries ago, in the intellectual atmosphere generated by the appearance of Hutton's Theory of the Earth (Hutton, J., 1795) as discussed by the authors.

TL;DR: In this paper, the present day kinematics of the major tectonic elements in Bulgaria, part of the northern extent of the Aegean extensional system, were determined based on the estimates of the velocities of 17 stations surveyed at least twice.

TL;DR: In this article, a geostructural study on active faults in central Italy, where seismogenic fault zones occur as part of a Quaternary network dissecting and/or inverting earlier tectonic features of the central Apennines fold and thrust belt, is presented.

TL;DR: In this article, the authors illustrate the second stage of a two-stage magmatic progression which affected the back-arc domain of the southern Tyrrhenian sea as well as its corresponding foreland of eastern Sicily and Strait of Sicily.

TL;DR: In this paper, the authors reproduce the highly heterogeneous strain field indicated by neotectonic and seismological data in the central-eastern Mediterranean region by finite element modeling, at a first approximation, of a 2D elastic thin plate.

TL;DR: A three-dimensional image of the Campi Flegrei caldera between 0 and 3 km of depth has been inferred by the inversion of P rise time and pulse width data of 87 local earthquakes recorded during the last bradiseismic crisis by a local array deployed in the area by the University of Wisconsin this article.

TL;DR: In this article, it was shown that the average measured increase in the length of the day is 1.8 ms per century, from which it was concluded that besides the tidal contribution there is another long-term component acting to decrease the Earth's rate of spin, which is consistent with recent measurements made by artificial satellites.

TL;DR: In this paper, the first arrival refraction data over mostly exposed Deccan Traps region were analyzed based on 2D ray tracing technique, from all the 25 shot points of this profile.

TL;DR: In the south-eastern Aegean region, stress and strain established in two stages, during the convergence of the African with the Eurasian plate: the late collision of the Hellenides and the fore-arc evolution above the Hellenic subduction, were recorded in this paper.

TL;DR: In this paper, the kinematic and strain history of the Albanian orogenic belt from the time of the Tertiary continental collision between the Apulian and European plates is investigated.

TL;DR: Paleomagnetic analyses of Upper Miocene synorogenic strata from the Marche-Romagna foothills of the Northern Apennines have been integrated with detailed structural work and structural modelling to gain new insights on the processes of tectonic rotation in fold-and-thrust belts as discussed by the authors.

TL;DR: In this paper, gravity tide observations have been conducted on the island of Lanzarote, with different gravimeters at different locations, and the cosine component of the final residual vector for station Cueva de los Verdes (northeastern of the island) depends on the ocean model considered.

TL;DR: In this paper, a geoelectrical survey using vertical electrical sounding was carried out to identify the geoclectric model of graben structure within the Gokova rift, since it can provide further useful information on the north-south extension in the western Anatolia.

TL;DR: In this article, four different thermo-kinematic models for the tectonic evolution of the convergence zone of the Eastern Carpathians are studied, in which processes like the precollisional subduction of an oceanic lithosphere, the underthrusting of the European continental margin in collision and the post-collisionality thermal relaxation control the long term thermal structure of the study area.
