kuh-e-siah is located in the north of gavkhuni lagoon and east of the varzaneh (se of isfahan) and is a part of urumieh-dokhtar magmatic arc (udma). the volcanic rocks of this area are vesicular basalt and basaltic andesite with late miocene age. the most common textures of these rocks are porphyry, microlitic porphyritic, hyaloporphyric and vesicular. plagioclase, olivine and clinopyroxene are...

jebale barez plutonic complex is composed of granitoid intrusive bodyes and is located in the east - north east jiroft and  southeastern province of kerman on the lengths of the 57° 45' east to 58° 00' and northern latitudes  28° 30' to 29° 00'. plutonic complex composed of granodiorite, quartzdiorite, monzogranite and porphyritic granite. the microstructures observed in thi...

Development of the sugar beet cyst nematode, Heterodera schachtii, was studied in growth chambers at 20, 25, 29, 32 and 35 ± 1 oC on Beta vulgaris cv. Saccharifera. The optimum temperature for reproduction appeared to be 32 oC, at which the life cycle, from second-stage juvenile (J2) to J2, was completed in 16-19 days; at 35 oC, 20-21 days were required. Juveniles emerged from eggs within 29 da...

salafchegan-khorhe volcanic rocks are exposed within urumieh-dokhtar magmatic belt. different kinds of volcanic and subvolcanic rocks of calc-alkaline to alkaline character have been reported throughout this magmatic belt. since, isotopic investigations are very useful for detection of magma petrogenesis and because no isotopic studies have been done in this area, so a geochemical and isotopic ...

Iranian Cenozoic magmatic belt, known as Urumieh-Dokhtar, is recognized as an important polymetallic mineralization which hosts porphyry, epithermal, and polymetallic skarn deposits. In this regard, multivariate analyses are generally used to extract significant anomalous geochemical signature of the mineral deposits. In this study, stepwise factor analysis, cluster analysis, and concentration–...

Abstract We present two robust and well‐dated paleomagnetic poles from upper Eocene Oligocene volcanics in the Urumieh‐Dokhtar magmatic arc, Central Iran. These place Iran ∼3.7°–3° of latitude south its position between ca. 40 23 Ma. Our new declination data indicate that block may have experienced a ∼11.6° clockwise rotation since Late Eocene. integrated our with retrodeformed margins Zagros c...
