The Davisian model elucidates landscape development through an orogeny by denudation processes, postulating prolonged still-stand of a landmass following rapid tectonic uplift, ultimately resulting in a peneplain. The Penckian model emphasizes that landscape is shaped by concurrent tectonics and denudation, and includes the primary peneplain as an antithesis against the Davisian end-peneplain b...
The SH waves from 21 underground nuclear explosions at Pahute Mesa (NTS) were used to investigate tectonic release. The equivalent double-couple representation of the tectonic release, which was constrained by waveform modeling and the polarity of sP, is very similar for all the explosions. The average orientation is a right-lateral, strike-slip fault trending N15°W. Seismic moments were determ...
Completion of a global geological map of Venus has provided documentation of the relative age relationships, spatial distribution, and topographic configuration of the major geologic units and permitted us to address several important problems concerning the volcanic history of Venus. We use these data to: 1) assess the stratigraphic position of volcanic units and landforms, 2) determine their ...
Abstract Early Paleozoic accretionary orogens dominated the Western Gondwana margin and were characterized by nearly continuous subduction associated with crustal extension back-arc basin development. The southwestern is represented Famatinian Pampean basement realms exposed in South America, both related to protracted evolution of Terra Australis Orogen, whereas northwestern mainly recorded Ca...
Linear systems analysis is used to investigate the response of a surface processes model (SPM) to tectonic forcing. The SPM calculates subcontinemal scale denudational landscape evolution on geological timescales (1 to hundreds of million years) as the result of simultaneous hillslope transport, modeled by diffusion, and fluvial transport, modeled by advection and reaction. The tectonically for...
Introduction: An understanding of the spatial and azimuthal distribution of lobate scarps on Mercury is important in constraining thermal history models and models for the origin of tectonic stresses [see 1]. Existing models involve either global (radial) contraction due to secular cooling of the interior, tidal despinning, or a combination of the two [1, 2, 3, 4, 5]. A comprehensive database o...
recently than others; Europa could experience current cryovolcanic and tectonic activity. Global-scale patterns of tectonic Images of Europa from the Galileo spacecraft show a surface features suggest deformation resulting from non-synchronous with a complex history involving tectonic deformation, impact rotation of Europa around Jupiter. Some regions of the lithocratering, and possible emplace...
introduction Active tectonic studies are one of the most important topics in earth science and their results are widely used for assessing natural hazards and land use development and management plans in populated areas (Pedra et al., 2009, 220).Among these, geomorphic indices have been effective in assessing active teconic in large areas due to their high speed and accuracy (Clare & Pinter, ...
The denudation budget of the Alps is quantified for the main period of lateral extrusion between 22 and 12 Ma. The relative importance of tectonic denudation increases from W to E from ,70% in the Lepontine window in the Swiss Alps to ,80% in the Tauern window and to more than 95% in the Rechnitz window. The driving mechanism of tectonic denudation was eastward extrusion due to an unconstrained...
