The relationship between mass movements and tectonic lineaments is investigated in the Pliocene sand and clay terrains of Montepulciano (Central Italy). Field mapping of geological and geomorphological features, remote sensing, aerial photograph
interpretation and morphometric analysis are used to determine the strength of the relationship between tectonics and landslides.

This paper simulates how the shapes of the hypsometric curves change through mountain building resulting from concurrent tectonics and denudation. Next, it discusses the relationship of the hypsometric curve to the stage of a geomorphic cycle
Morphological, sedimentological and tectonic features of Diamante-M. Carpinoso marine terrace flight (Tyrrhenian coast of Northern Calabria, Italy)
Marine terrace flights resulting from the interaction of Quaternary glacio-eustatic fluctuations and tectonic uplift are a typical feature of the Tyrrhenian coast of Calabria in Southern Italy; in particular a terrace flight with four orders
of terraces is evident in the Diamante area. The aim of this study was to define the type of tectonics that acted in the area and to determine its effects, based on morphologic, morphotectonic, sedimentologic and stratigraphic evidence.
The effects of deforestation on slope and channel evolution in the tectonically active Darjeeling Himalaya

The main indicators of Quaternary tectonic uplift are the young mountain slopes of the Darjeeling Himalaya. Owing to deforestation and extensive land use, the earlier natural tendency of a dominance of channel incision over slope degradation has
Various tectonic disturbances from the Cretaceous to the present day have modified the geomorphic features of western India. Compression and extensional stresses generated by the northerly moving Indian plate, and its collision with the Eurasian
plate, have brought about frequent changes in the drainage system and other features. The AA. attempt to establish the chronology of the landform development condidering the records of the tectonic events, sedimentation in different adjoining basins

Two main points are raised in replying to Fabel et al. (1993) in their discussion of the paper by Bishop and Brown (1992). The total evidence for rebound is now known to be regional in extent, supporting the relevance of a regional isostatic model
. The AA. note that isostatic rebound need not to be continuous, so that evidence of episodic rebound does not conflict with it, and that a lack of isostatic rebound would require a strongly opposing active tectonic regime. A key general conclusion
is that denudational rebound should always be assessed as an explanation for uplift before active tectonism is invoked.
rates should be extrapolated to catchment-wide rates. At the local scale of the Lachlan River highlands, active tectonic compression may be more important than flexure, which is more important at a regional scale.

In the crystalline basement of northeastern Bavaria, a part of the Variscan fold mountains, apatite fission-track analyses were for the first time applied to determine the influence of tectonics on landform development. The results show
that the studied area was subject to a strongly differentiated tectonic development in the course of the entire Caenozoic.
Application fo paleokarst studies in dating of tectonic events and morphology formation in an intensively faulted area (an example from the Carpathian Foredeep, Southern Poland)
A series of 26 Quaternary shorelines, stepped between present sea level and 556 m , are studied. They are part of the flight of marine terraces of the Aspromonte region. In a region where tectonics is particularly active (earthquakes occur
frequently), it is important to determine the relationships between this flight of shorelines, the glacio-eustatic oscillations and tectonics.
Normal fault-generated mountain fronts are a characteristic element of the landscape in the Central Apennines. The purpose of this work is: 1) to recognize the recent activity of the tectonic structures responsible for their formation; 2

in the vicinity of Death Valley, however, the depositional area is only about half the size of the erosional area. This reflects the more active tectonic environment in these bolsons.
The Sudetes Montains are characterised by a residual tectonic topography, the typical landform being mature fault-generated range fronts originated during the Late Tertiary. The general pattern of neotectonic movement in this area can be inferred
from analysis of drainage systems and the distribution of erosion surfaces. The aim of this paper is to outline the usefulness of some landforms in neotectonic reconstructions in tectonically less active areas.

Eleven backhoe trenches were excavated across six Quaternary fault scarps on the northeastern margin of the Basin and Range extensional tectonic province. Fifteen palaeoseismic events can be recognized, bracketed by radiocarbon or thermoluminescence
This study presents the results of geomorphological mapping at a scale of 1:5000 undertaken to identify landforms in the eastern Argive Plain which may have a tectonic significance. It aims to correlate morphotectonic observations of fault scarps
