  • Is Australia a tectonically stable continent? Analysis of a myth and suggested morphological evidence of tectonism

  • Australia ; Concept ; Fault ; Geomorphology ; Myth ; Neotectonics ; Seismicity ; Shield ; Tectonic stability
  • 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

  • of the high Agri Valley. The geological evolution of the Agri Valley is essentially related to the Pleistocene extensional and strike-slip tectonics, overprinting older Apennine contractional structures. The geological formations recognized in the study area
  • Tectonic landforms and Quaternary tectonics in Japan
  • 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).

  • Tectonic geomorphology
  • 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

  • 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
  • Large scale modelling of drainage evolution in tectonically active asymmetric intermontane basins using cellular automata

  • Andalusia ; Drainage network ; Fault ; Graben ; Gully erosion ; Model ; Spain ; Tectonics
  • 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.
