construction and validation of the translation teacher competency test and the scale of students’ perceptions of translation teachers
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
Mineral Chemistry and metamorphic evolution of the Late Neoproterozoic metabasites of Do-Chah metamorphic - igneous complex (SE Shahrood)
Metapelites of the Do Chah complex (SE Shahrood) are composed of micaschist, garnet micaschist, chloritoid schist and garnet-bearing gneiss. In the highest degree of metamorphism, metapelites have been affected by partial melting, resulting as granitization. A significant part of these rocks, imposed by compressional tectonic regime and show typical evidence of plastic deformation and intensive...
متن کاملMagmatic and Metamorphic Fluids in Pegmatite Development: Evidence from Borujerd Complex, Iran
The Borujerd complex of western Iran is composed of intrusions and their surrounding contact aureole, with, pegmatites and quartz veins. Pegmatites differ in mineralogy, origin and age, and two groups can be distinguished. The Older Pegmatites (about 120 Ma age) intruded contact metamorphic rocks from the early magmatic stage, while the Younger pegmatites (52-70 Ma age) formed during the late m...
متن کاملMineral chemistry and thermobarometry of the Late Neoproterozoic metabasites from Do-Chah metamorphic-igneous complex (SE Shahrood)
Do-Chah metamorphic-igneous complex is one of the Iranian crystalline basement complexess which is located in the SE Shahrood in northern edge of Central Iran structural zone. This complex includes a wide compositional range of metamorphic rocks such as metabasite, metapelite, metacarbonate and metapsammite, and meanwhile is host of leucogranite and biotite granite intrusions. Protolith of meta...
متن کاملبررسی کانی‌شناسی و ژئوشیمی گرانیتوئید منطقه‌ی لاله‌زار (بردسیر- استان کرمان)
Lalezar Granitoid Complex is located in the south-east of Urumieh-Dokhtar volcanic belt and Dehaj-Sarduieh belt (Kerman Province). It contains plutonic rocks with granitoid composition and has been intruded into the Eocene volcano-sedimentary rocks. The plutonic rocks have granite to gabbrodiorite composition with dominance of tonalite and diorite rocks. The main mineral phases are sodic plagio...
