But A. Wegener did not have the specialisation to correctly weight the quality of the geophysical data and the paleontologic data, and its conclusions. Wegener's main interest was meteorology, and he wanted to join the Denmark-Greenland expedition scheduled for mid 1912. So he hurried up to present his Continental Drift hypothesis. [2]
Map of the later North Atlantic region after the closing of the Iapetus Ocean and the Caledonian/Acadian orogenies (Wilson 1966).Animals: Trilobites and graptolites. [1] [2] Euramerica in the Devonian (416 to 359 Ma) with Baltica, Avalonia (Cabot Fault, Newfoundland and Great Glen Fault, Scotland; cited in Wilson 1962) and Laurentia (Other parts: Iberian Massif and Armorican terrane).
Tectonophysics, a branch of geophysics, is the study of the physical processes that underlie tectonic deformation. This includes measurement or calculation of the stress - and strain fields on Earth’s surface and the rheologies of the crust , mantle , lithosphere and asthenosphere .
Extensional tectonics is associated with the stretching and thinning of the crust or the lithosphere.This type of tectonics is found at divergent plate boundaries, in continental rifts, during and after a period of continental collision caused by the lateral spreading of the thickened crust formed, at releasing bends in strike-slip faults, in back-arc basins, and on the continental end of ...
The term Mediterranean-Mjosa Zone (Mittelmeer-Mjösen-Zone) was coined by the German geologist Hans Stille in about 1930 to describe a rift in the continental Crust crossing Europe from the Mediterranean Sea via Marseille, the Rhine rift as far as Mjøsa in the south of Norway, a total length of 2000 km.
The historical development of geophysics has been motivated by two factors. One of these is the research curiosity of humankind related to planet Earth and its several components, its events and its problems.
The final major cold spell occurred from 25,000 to 18,000 years ago and is known as the Last Glacial Maximum when the Fenno-Scandinavian ice sheet covered much of northern Europe while the Alpine ice sheet occupied significant parts of central-southern Europe. However, there were several less cold periods after this.
Tectonophysics, The International Journal of Geotectonics and the Geology and Physics of the Interior of the Earth is a weekly peer-reviewed scientific journal published by Elsevier. It was established in 1964 and covers the field of tectonophysics , including kinematics , structure, composition, and dynamics of the solid Earth at all scales.
