One of the efficient factors in comprehensive development of an area is to provide water sources and on the other hand the appropriate management of them. Population growth and nourishment security for such a population necessitate the achievement of constant development besides the reforming of traditional management in order to increase the profit of sources; In this case, the constant exploi...

Tectonic processes are major factors controlling landform development in tectonically active areas. In order to evaluate quantitative measurement of tectonic activities in the Alamarvdasht basin in the south of Iran, six different morphological indices including stream-gradient index (SL), drainage basin asymmetry (Af), hypsometric integral (Hi), valley floor width-valley height ratio (Vf), dra...

The Gurpi Formation, one of the geologycal units of the Zagros Basin, stretches with in the Folded Zagros in the provinces of Khuzestan, Lorestan, and Fars,in southwest Iran. In all 525 samples were collected from five stratigraphic sectiones of the Gurpi Formation in Dezful embayment Zone for studying biostratigraphy. Totally 47 species from 23 Planktonic foraminifera genera were recognized in...

Study area is located in the higher folded belt in the Zagros Mountain in the Iraqi Kurdistan. Analyzed geomorphic indices included sixteen sub basins: the stream gradient index (SL), drainage basin asymmetry (AF), hypsometric integral (Hi), Valley floor width-valley height ratio (VF) and mountain front sinuosity (J) is obtained relative of tectonic activity in the study area. These indices abo...

The present study focused on redescription of Gammarus pseudosyriacus (Karaman & Pinkster, 1977) based on new materials from Zagros Mountains and describes a new subspecies of freshwater amphipod, Gammarus pseudosyriacus issatisi subsp. n., from the southern Zagros Mountains. The work is based on morphological and morphometric comparisons. This new subspecies has features similar to Gammarus ps...

The Late Cretaceous is marked by geodynamical changes including Africa-Eurasia convergence that resulted in the narrowing of Tethys Ocean and ophiolite obduction along southern margin various continental blocks eastern Tethys. Geochemical mineralogical analyses were performed on Shahneshin section (Zagros Basin - Tethys), to explore consequences this evolution oceanic circulation, estimate role...

Abstract. Recognition of a new angular unconformity and the synthesis detrital zircon U–Pb (U–Th) / He provenance records, including double dating, from NW Zagros region elucidate basin dynamics foreland wedge-top intermontane units, as well tectonic processes in source terranes response to different geodynamic phases. In this contribution, we present field observations data hinterland basins r...
