topographic profiles of parts of the Kali River Basin bring out preferred stream migration in response to Quaternary ground tilting of southeast and northwest directions across the North Almora Thrust. An oblique-slip type of movement along the fault has been

The study area is located close to the principal thrust of the Gran Sasso d’Italia massif, whose landforms are mainly controlled by geological, structural and glacial processes. In fact, important morphostructures have been identified as being
linked to the direct action of tectonics at the macro-scale level, as in the case of the orientation of the principal valleys. Tectonics have also promoted the spread of gravitational phenomena. The glacial footprint is evident in the numerous inactive
of the epicenters of the events are very close to the Main Central Thrust (MCT), in between Munsiari Thrust (MT) and Berinag Thrust (BT). The neotectonic investigations were carried out in the major river valleys of the Kumaun Himalaya. From the investigations some
new faults are identified on the basis of geomorphological signatures. The morphotectonic development has been related to the prevalent seismicity of the region. It is evident that the major thrust and faults of the region are seismically as well
as neotectonically active in some segments. From the ongoing seismic and neotectonic movements it is clear that some of the faults and thrusts are active at present.
and with axes striking between EW and NWSE. These folds are not related to thrusttectonics. Two different fault systems oriented NS and EW were evidenced ; the first one is constituted prevalently by normal faults, whereas, the faults of the second system shows
This study is aimed to provide a direct evidence about the composition, density and P-T parameters of the fluid generated along the basal plane of a moving thrust sheet. Fluid inclusions in newly formed minerals synkinematically grown in basal

Field studies coupled with interpretation of topographic maps resulted in the identification and delineation of a large number of trending active faults which post-date the NW-SE oriented thrust system and shear zones. Recent movement
on the northerly-trending faults has caused not only pronounced deflection of rivers and streams but also damage to recently constructed river bridges and subsidence of roads. Movements along faults and thrusts are also responsible for the abrupt rise of mountain
Basic regional crustal setting and superimposed local pluton-intrusion-related tectonic in the Larderello-M. amiata geothermal province, from integrated CROP seismic data
The purpose of this work is the reconstruction of the crustal tectono-stratigraphic setting of the area extending from the Tyrrhenian coast to the M. Cetona thrust. The results obtained are very important and decisely innovative as regard
Debris entrainment by basal freeze-on and thrusting during the 1995-1998 surge of Kuannersuit Glacier on Disko Island, west Greenland
Kuannersuit Glacier, a valley glacier on Disko Island, experienced a major surge from 1995 to 1998. The aim of this study is to describe the tectonic evolution of large englacial thrusts and the processes of basal ice formation using a multiproxy
approach including structural glaciology, stable isotope composition (δ18O and δD), sedimentology and ground-penetrating radar. The AA. argue that the major debris layers that can be traced in the terminal zone represent englacial thrusts that were formed
is mobilized in the vein system of ice. Their results have important implications for understanding the significance of basal ice formation and englacial thrusting beneath fast-flowing glaciers and it provides new information about the development of landforms
of the Apennines onshore. Syntectonic basins are narrow, long-range stratigraphic continuity is likely to be the exception rather than the rule. This challenges some of the assumptions behind existing tectonic models for the Apennines and similar orogens. - (NF)

. Mass movement scars were mapped in the field. Chi-square analyses revealed that the frequency of slope failures varies with slope aspect, and position above/below the Main Central Thrust (MCT). Human disturbance did not account for a statistically
. Imprints of active tectonics on the landforms are discernible in the form of tilted fans, colluvial deposits and terraces, truncation of toe of fan, linear fault scarps and thrusting of Siwalik rocks over the colluvial deposits. OSL dates for fans
and terrace deposits indicate tectonic activities between 8 and 56 ka. It is showed that geomorphic evidence, chronology of depositional landforms, deformation of Quaternary landforms and soft-sediment deformation structures provide baseline information about
The Umbria-Marche Apennines, an arc-shaped fold and thrust belt form the external part of the Northern Apennines. The AA. suggest that this fold-thrust belt can be divided longitudinally into 2 sectors. The boundary between the eastern and western
and tectonic evolution of the region. However, it also possible that the Western and Eastern Umbria-Marche Apennines represent completely different orogenic systems, with different causes - possibly with the former related to Corsica-Adria collision

A long-term approach based on detailed mapping and lichenometry provides additional information concerning talus-foot rock glaciers overstepping raised beaches in Svalbard. Their regional distribution is primarily controlled by the tectonic pattern
and especially by the network of major thrusting faults. Tentative dating of the start of the rock glaciers movement combined with data on their longitudinal development allowed to infer average long-term rates of rock glacier movement and to compare them
that Southern and Western parts of Dinarkooh are tectonically more active and also Samand active fold plays a significant role in this activity because of an active blind thrust fault beneath it. - (NF)
Drainage networks are usually influenced by the type, orientation and recent activity of regional and local faults and folds in tectonically active regions. In the Zagros Mountain Range, Western Iran, most drainage systems are controlled
by neotectonics processes. The development of the drainage system of Dinarkooh region in the late Quaternary depends mostly on the activity of Main Zagros Thrust Fault (MZTF) and similar NW-SE oriented faults in Zagros fault system. The AA. have done
