allochthonous masses are common structures in zagros fold-thrust belt. they are generally considered as collapse structures formed by the influence of gravity and in rock units with competency contrast. however, large allochthonous masses mapped in dowgonbadan area in dezful embayment near the mountain front fault (mff) of zagros show characteristics different from the belt common collapse stru...

Abstract Integrated geophysical mapping benefits from visualizing multi-source datasets including gravity and satellite altimetry data using 2D 3D techniques. Applying scripting cartographic approach by R language GMT supported traditional in QGIS is presented this paper with a case study of Iranian geomorphology special focus on Zagros Fold-and-Thrust Belt, unique landform the country affected...

The Bitlis-Zagros Fold-Thrust Belt is one of the world?s largest deformation zones, extending from Eastern Mediterranean in southern Turkey to south Iran. This zone partitioned between different structures; however, little known about relative activities these structures and their effects on topography. An area located northern part Bitlis- Zagros Belt, just Anatolian Plateau was studied detail...

We studied the behavior of earthquake network using HEALPix spherical pixelization and square cells methods. In first method, geographical region is divided into isolatitude rhombic-spherical same areas method. second we equal cells. To construct a network, if an happens in cell, that cell will become node, two nodes be connected with edge for successive events. The built from Iran’s seismic da...

A comparative petrological study was conducted on the columnar joints of Guryongpo, Pohang, Yangnam, Gyeongju, and Gangdong-hwaam, Ulsan in Cenozoic Miocene sedimentary basin. Horizontal joints, these are characteristically developed, cross-sectional shape each joint is predominantly quadrilateral pentagonal Guryongpo Yangnam to hexagonal Gangdong-hwaam joint. As a result XRF analysis, it confi...

In this paper the geometrical relationship of the folds which exist in the Folded Zagros Mountains, including Asef Mountain (northern Iran), were studied. The southern and western zones of the Zagros Mountains are called the Folded Zagros. These zones extend approximately 1,375 km in length with a width ranging from 120 to 250 km. Asef Mountain is located in northern Shiraz (from northern Sarda...

in current paper, geometrical relationship between the longitudinal faults of a zone of the folded zagros, surrounding asef mountains (north of shiraz) that follow the northwest-southeast structural trend (eg. zarghan, katah and sadra faults) has been studied. a western and southern zone of zagros mountain chain called folded zagros has a length of about 1375 km and a width between 120 and 250 ...

We have dated the South Delhi orogeny, Aravalli-Delhi Mobile Belt (ADMB), NW India, using tectonic fabric, geochemistry, and zircon-monazite geochronology as proxies. The Terrane (SDT), a passive margin domain in ADMB, consists of multiply deformed (D 1 –D 4 ) greenschist facies rocks several granite plutons. D deformation is characterized by pervasive isoclinal recumbent F fold axial planar te...

In the Southern São Francisco Craton near Itapecerica (Minas Gerais – Brazil) occurs a supracrustal succession of rocks, varying from bottom to top by quartzite, graphite schist, khondalitic paragneiss and banded iron formation whose protoliths are oceanic basin with ages in context Rhyacian-Orosirian orogeny. Amphibolite metaultramafic bodies occur associated this succession. Mineralogical tex...
