Mélange in the Trondheim Nappe suggests a new tectonic model for central Norwegian Caledonides
Extensive mélange exists near the base of the Trondheim Nappe, indicating tectonisation of syndepositionally deformed chaotic deposits. The mélange is associated with other features that are characteristic of forearc accretionary prisms
. Such a tectonic setting for the Trondheim Nappe has profound implications for the evolution of the Scandinavian Caledonides.

L’analyse des isotopes de l’uranium et des macroéléments hydrochimiques contenus dans les eaux minérales dans la partie Est de la source de Tcheboksary a démontré que ces eaux minérales sont à l’origine du mélange des eaux fermées du Permien
Zur tektonischen Bearbeitung von Bohrkernen. (Tectonical treatment of drill cores)
Methodological references are given concerning the collection, documentation and evaluation of structural tectonic elements of cores. This is followed by the discussion of the most important results of investigation which are not only of regional
importance but of general interest with respect to tectonic questions, particularly joint tectonics. (HL).
In this review, the A. examines the important developments in tectonic geomorphology at a wide range of spatial and temporal scales and the growing interest of geologists in geomorphology in general, and tectonic geomorphology in particular
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.
Strukturtektonische Arbeitsmethoden der Glazialtektonik. (Structural-tectonic working methods in glacial tectonic)
Structural tectonic working methods as used in the foundation rock and in the rock mechanics can be applied to the survey, documentation and interpretation of glacigenous deformations. Introducingly, experience in the finding-out of the pebbles
Occasional references to the relative tectonic instability of the Australian continent have been published over the last hundred years. Despite this, it was repeatedly claimed that the shield lands in particular were tectonically stable
, and as recently as this century reference has been made to a concept embracing a tectonically inert continent. However, analyses of seismicity and faulting and regional geological mapping revealed widely distributed tectonic forms and especially fault-related
The aim of this paper is to model the sensitive of drainage systems to increased regional gradient at both the river-network scale and gully-system scale. The research is applied to a semi-arid region experiencing extensional tectonic activity
. The main assumption made throughout the paper is that large-scale tectonic stresses cause geological blocks to tilt and this has a profound influence on the drainage systems.
