Amphibolitic rocks are the main part of the north of Khoy metamorphic complex. Petrographicaly these rocks are normal amphibolite, muscovite amphibolite, biotite amphibolite, garnet amphibolite and pyroxene amphibolite. The protolith of these rocks is mainly igneous. These rocks belong to tholeiitic and calc-alkaline series and Ocean Floor Basalt and Arc tectonic setting. These two distinctive ...
Any comprehensive model for earth history consistent with the data from the Scriptures must account for the massive tectonic changes associated with the Genesis Flood. These tectonic changes include significant vertical motions of the continental surfaces to allow for the deposition of up to many thousands of meters of fossil-bearing sediments, lateral displacements of the continental blocks th...
This article is aimed to give the first results of the project studying the faults and tectonic style of the southwestern part of Turkey based on remote sensing techniques. LANDSAT-TM and ASTER satellite data have been used in visual interpretation. The several techniques based on DEM have been applying to interpret in the determining of the tectonic features. The anaglyph image produced from L...
A stratigraphy of a buried travertine deposit was developed using stable isotope geochemistry, trace elements, and radiometric dating. The identified in well at Prima Porta (north Rome, Italy), located the western boundary Tiber Valley, morpho-tectonic depression extensional origin. It deposited close to spring that discharged groundwaters from nearby volcanic aquifer associated with rise deep-...
The lagoonal and shallow marine sediments of the Penarth Group in UK span Triassic–Jurassic boundary. These contain several disturbed levels with soft sediment deformations (SSDs), such as synsedimentary faults, injective domes, recumbent folds slumps that are recognised most basins from SW England South Wales to NW Northern Ireland. Field observations, notably close link SSDs active attest an ...
The origin and geochemistry of the sediments that make up the Khuzestan plain as one of the key areas of southwestern Iran has always been discussed. Detailed geochemical studies of these sediments, in addition to determining their origin, can provide appropriate information about weathering, erosion, ancient tectonics and environmental pollution in the Khuzestan plain. In this research, after ...
The goal of avoiding distraction (e.g., ignoring words when naming their print colors in a Stroop task) is opposed intrinsically by the penchant to process conspicuous and correlated characteristics of the environment (e.g., noticing trial-to-trial associations between the colors and the words). To reconcile these opposing forces, the authors propose a tectonic theory of selective attention in ...
In the early 1920s, the continental displacement theory of Wegener, latitude studies of Koppen and Wegener, and Argand's ideas on mountain building led to the first mobilistic paleogeography. In the 1930s and 1940s, many factors caused its general abandonment. Mobilism was revived in the 1950s and 1960s by measurements of long-term displacement of crustal blocks relative to each other (tectonic...
Magnetic lineation in rocks is given by a cluster of the principal axes of maximum susceptibility (Kmax) of the Anisotropy of Magnetic Susceptibility (AMS) tensor. In deformed rocks, magnetic lineations are generally considered to be the result of either bedding and cleavage intersection or they parallel the tectonic extension direction in high strain zones. Our AMS determinations, based on a v...
