The Alboran Basin and the surrounding Betic-Rif Cordilleras (see Fig. 1) constitute an arc-shaped thrust-belt that exempli®es contemporaneous internal extension and frontal thrusting in an overall compressional setting. The complex tectonic evolution of the region is the result of ongoing convergence between Africa and Eurasia since late Mesozoic. Until the amalgamation of Iberia with Europe, f...
Changes in seismicity rates, whether of tectonic or of induced origin, can readily be identified in regions where background rates are low but are difficult to detect in seismically active regions. We present a novel method to identify likely induced seismicity in tectonically active regions based on short-range spatiotemporal correlations between changes in fluid injection and seismicity rates...
The association of coal and oil shale had been a hot topic for a long time. Various types of association of coal and oil shale can be found in one basin, for instance, the coal can act as the roof or floor or interlayer of the oil shale, etc. The most crucial factor for the formation of oil shale is stratification and seasonal blooming of lower plankton, while the final formation of the coal st...
Understanding the mechanisms and controlling factors of erosion rates is essential in order to sufficiently comprehend bigger processes such as landscape evolution. For decades, scientists have been researching erosion rates where one of the main objectives was to find the controlling factors. A variety of parameters have been suggested ranging from climate-related, basin morphometry and the te...
Venus is a planet that is similar to Earth in terms of some important planetary parameters (size, mass, position in the solar system, presence of atmosphere) and different in terms of other, equally important ones (absence of an intrinsic magnetic field, large atmospheric mass, carbon dioxide composition of the atmosphere, lack of water, very high surface pressure and temperature). The surface ...
Marine tidal notches are developed by bioerosion in the intertidal zones of rocky coasts, but a combination of sea-level change and crustal movements can result in them being raised above or submerged below the water line. For that reason, the present-day elevation of these former shorelines relative to mean sea level has long been used to quantify relative coastal uplift and subsidence in tect...
[1] Climate change indirectly alters the distribution of tectonic uplift at active orogens by modifying the action of surface processes, which in turn alters mountain topography. The impact of alpine glaciation on tectonic activity is explored here. The predictions of previous analytical, critical wedge models are compared with the output of a numerical model that explicitly couples rock uplift...
Introduction The vertical and horizontal movements of the Earth crust have caused extensive changes in surface phenomena, in the active tectonic regions. In order to measure some of these changes, morphometry analyses have been used to evaluation of the amount of tectonic activity. These analyses are useful tools for analyzing existing feature at the ground level and provide a proper understan...
