the present study is an experimental case study which investigates the impacts, if any, of skopos on syntactic features of the target text. two test groups each consisting of 10 ma students translated a set of sentences selected from advertising texts in the operative and informative mode. the resulting target texts were then statistically analyzed in terms of the number of words, phrases, si...

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 ...

Basalts in the Gasht-Masuleh area crop out in the SW Fuman, Gilan Province, and are exposed in the Jurassic and Late Cretaceous units in this area. Whole rock chemistry shows that the rock samples have Mg numbers between 30 and 31.7. Rare earth element patterns (REE) indicate light REE (LREE) enrichment and heavy REE (HREE) depletion (LaN/YbN= 7.7-9.8). Nb, Ta and Ti negative anomalies in primi...

This article provides a background for scientists interested in a general overview of the geology and geomorphology of Turkmenistan. The basement of Turkmenistan is a complex amalgamation of arc-related terranes developed in the Asiatic and northern Paleotethys oceanic domains during Late Paleozoic to Triassic times. A major part of the country coincides with the Turan Platform, where a thick s...

The Etive igneous complex has intruded into Dalradian and Moine meta-sedimentary rocks in Devonian. Main rock types of the complex are granodiorite, monzodiorite, monzogranite, granite and diorite. Geochemical studies show that the magmas were of high K calc-alkaline, I-type and metaluminous nature. Application of discriminant diagrams to the Etive rocks indicates a possible within-plate tecton...

Khoy ophiolitic complex in northwest of Iran have several chromitite bodies with various textures, different geochemical features and associated minerals. Based on Cr#, Khoy chromitites are divided into two groups: high-Cr (Cr# > 0.6) and high-Al (Cr# < 0.6) chromitites. The high-Cr contain some amount of PGEs with tiny grains of platinum-group minerals (PGM), whereas, high-Al chromitites are p...

Gabbroic complex of Soltan Abad is Located about 35 Km east of Sabzevar. According to tectonic classification, the study area is part of Sabzevar ophiolitic zone. The composition of these intrusion bodies are vary from gabbro to gabbro-diorite. The main minerals of gabbroic rocks are plagioclase (bytonite), clino-pyroxene and ortho-pyroxene (enstatit – hyperestene) and accessory minerals are ap...

The Kermanshah Ophiolite Complex (KOC) lies in the structural – tectonic zone of western Iran in northern part of Zagros main thrust and is a part of highly dismembered Kermanshah – Panjvin Ophiolitic belt. The best outcrops of the sheeted and isolated dykes in this complex are present in south of Sahneh area. They are basic in composition. The geochemical studies show parent magma is in its in...

The Meiduk porphyry copper deposit is located in the northwest of Dehaj- Sarduieh volcano- sedimentary complex in Kerman (southeast of Urumieh- Dokhtar volcano-plutonic belt) and about 42 Km northeast of the Shahr-Babak. The Meiduk porphyry stock with an age 12.5 Ma intruted into Eocene volcanic rocks with andesite, andesitic-basalt and dacite composition (Razak complex). Petrographic studies i...
