Revue bibliographique des grands concepts de la tectonique desplaques. Illustrations nombreuses, à partir des principales orogenèses connues. Point de vue nuancé qui met l'accent sur la précarité des connaissances touchant aux relations entre
orogenèse et tectonique desplaques, ainsi que sur certaines contradictions entre la théorie et les observations sur le terrain. (LF).
Vitesses de déplacement desplaques lithosphériques en mm par an. Processus aléatoire de Markov avec deux dimensions fractales reflétant la cinématique statistique desplaques lithosphériques.
Une distribution systématique desplaques les plus importantes est nettement dégagée et attribuée à des courants de convection impliquant tout le manteau, à partir de la lithosphère jusqu'au noyau. (E. Bonnet).

This paper presents the results of geophysical, geological and geochemical studies of the eastern Indonesian region and their preliminary interpretations as regards tectonic development in an arc-continent collision zone.

L'ouvrage rassemble les cartes des limites géophysiques océan-continents : limites par les lignes de rivage, limites par les marges desplaques tectoniques.
This paper describes the plate tectonics setting, geology, topography, precipitation, erosion processes, sediment yield, and geomorphology of the Himalaya, and, using a climato-tectonic framework, discusses the north-south variation in geomorphology
The AA. report new field observations on stratigraphy, sedimentology, and geochemical data of plutonic rocks of the Shyok suture zone separaring the Ladakh terane to the SW from the Karakoram terrane to the NE. Six tectonic units have been
distinguished. The AA. outline the geology along a transect in the Nubra-Shyok river valleys. They describe a thick sedimentary-volcanic succession yielding Middle Cretaceous foraminifera. They also discuss the tectonic implications for regional correlation

For an investigation of the relation between the morphology and the tectonics in the Macaronesian Islands (i.e. the geographical group of middle Atlantic Islands between 10°N and 40°N, orientations studies have been made of steeply dipping joints
of volcanic origin, has been significantly codesigned by tectonic processes.
) drainage anomalies. The results have been checked in the field and compared with the tectonic features in the mountainous areas. The extension of these structures could then be traced confidently further towards the flat lowlands.
The effect of the Late Cenozoic tectonics (neotectonics) and their associated morphotectonics on the Nile Delta basin since the Late Miocene are discussed. The Nile Delta site seems to be affected by basement-related tectonics as it is located
