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]
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 .
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).
To begin with, the terminology and definition of what constituted geological study had to be worked out. The term "geology" was first used technically in publications by two Genevan naturalists, Jean-André Deluc and Horace-Bénédict de Saussure , [ 18 ] though "geology" was not well received as a term until it was taken up in the very ...
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 European Cenozoic Rift System (ECRIS) is a 1,100 km (680 mi) long system of rifts formed in the foreland of the Alps as the lithosphere responded to the effects of the Alpine and Pyrenean orogenies.
Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') is the scientific theory that Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.
The Alpine orogeny is caused by the continents Africa, Arabia and India and the small Cimmerian Plate colliding (from the south) with Eurasia in the north. Convergent movements between the tectonic plates (the African Plate, the Arabian Plate and the Indian Plate from the south, the Eurasian Plate and the Anatolian Sub-Plate from the north, and many smaller plates and microplates) had already ...
