The possible interactions between tectonics and landform formation in an active chain are examined by considering the case example of the Southern Apennines fold-and-thrust belt, in which frontal accretion and back-arc extension coexisted. The study
of the morphotectonic evolution of the belt in order to obtain a chronologically constrained reconstruction of the tectonic and erosional events occurred.
The origin of macroforms has come to the fore in geomorphology due to the spreading of plate tectonics. A new genetic typology is suggested by author which is meant to promote research into continental plate tectonics. (DLO).

important factors controlling the relief formation (such as basement and sedimentary mantle structures, neotectonics, Pre-Quaternary erosion and sedimentation, glacial erosion and accumulation during the Pleistocene) as well as some quantitative indices
allow to distinguish several types of large and very large landforms at the NW Russian Plain, as follows: tectonic| tectonic-erosional, mostly due to fluvial erosion| tectonic-erosional, mostly due to glacial erosion| tectonic-accumulative| built-up
, with erosional socle preconditioned by tectonics| built-up, with erosional socle| built-up| formed by glacial erosion. (Ed.).
Symmetrical peculiarities of planetary relief structure may allow to suppose that the main process of the Earth's development during the Post-Gondwanian epoc (middle Jurassic-Cenozoic period) was anisotropic expansion, mainly in the south hemisphere
. Other tectonic processes, including lithospheric plate displacements, occur simultaneously with the normal process of the Earth's expansion.
The results of the morphostructural analysis based on detailed geomorphologic mapping and on analysis of fissures and fault tectonics as well. The position and the altitude of the Paleogene planation surface relicts allow to assume tectonic
Cet atlas décrit les différentes formes de relief qui existent à la surface de la terre et explique leur formation. Il est illustré de photographies commentées de toutes les régions du monde. - (D. Rouvière).
Detailed geomorphological analysis of the relief forms in the presumed inundation area of the Krkavec dam on the Nežárka river in South Bohemia. Geological and tectonic characteristics, fluvial, eolian, gravitational, organogenic and antropogenic

The algorithm and program Relief are discussed which aimed for identification of regional and local components in the surface topography| the technique had been tested at the west Caucasian foreland. The efficiency of the geomorphological study
using computer is shown as applied to structural-tectonic investigation of oil and gas bearing regions.
La prise en compte de toute la série de phénomènes affectant le relief, depuis l'émergence des microfractures jusqu'à leur transformation en un linéament bien visible dans le relief permet la reconstitution des structures tectoniques qui régissent
. In this material a ferricrete developed in a low landscape position by lateral migration and absolute enrichment of iron. Subsequently, relief inversion brought the hard ferricrete into its present high position. Compositional differences such as Al-goethite

Utilisation des méthodes probabilistes, plus spécialement des chaînes de Markov, pour étudier l'évolution du relief. L'A. considère comme états des chaînes diverses formes du relief ayant certaines caractéristiques géométriques. Tout le système
évolue dans le temps comme un processus probabiliste. A partir d'un relief initialement horizontal, compte tenu de la vitesse de l'érosion, des mouvements verticaux et du temps, beaucoup de reliefs possibles peuvent se former. Quand tout le relief est
érodé, le processus s'arrête. L'A. donne quelques applications simples reflétant divers modèles d'évolution du relief.
Etude de l'évolution géomorphologique des Alpes orientales en réponse à la tectonique du Miocène. Présentation des 5 domaines géomorphologiques principaux : les hauts reliefs dans les parties occidentales et centrales des Alpes orientales; les zones
de relief intermédiaire avec des reliques de paléosurface à l'est du Hohe Tauern; les hauts plateaux karstiques des Alpes Calcaires du Nord; les zones de faible relief; les vallées longitudinales. Mise en évidence de 3 périodes dans l'évolution
The AA. analyze relationships between fault and joint tectonics and landforms in the south-western part of the Broumovská vrchovina (Bohemian Massif), where the surface topography is strongly influenced by the tectonics and lithology of the Upper
Quaternary development of Kateřinohorská Vaul relief in the Krušné hory Mountains
The relief development of the region was in the Quaternary period more influenced by tectonic movements than by climatic oscillations. A more intensive erosion due to younger upliftings erased traces of relief. Considering the character
The A. examines briefly the general outlines of the relief in Finland, bedrock and surficial landforms, their origins, and the factors that have affected their development. The basic framework for the relief in Finland is formed by the highly eroded
