Future changes (2015–2100) in precipitation and meteorological droughts Lake Urmia Basin were investigated using an average mean ensemble of eight general circulation models (GCMs) with high-resolution datasets socioeconomic pathway scenarios (SSPs) from the Coupled Model Intercomparison Project (CMIP6). In order to project drought, standardized index (SPI) was calculated. Overall, results reve...

Some populations of Gundelia tournefortii were compared based on chemotaxonomical characteristics. In this study, some biochemical compounds such as total protein and storage proteins of shoot were studied. The populations were compared on the basis of biochemical characteristics using statistical methods. Different populations were collected from mountains of west Azarbaijan province. Total pr...

The early Cambrian Takab iron ore deposit is situated in the northern part of Sanandaj-Sirjan zone, western Iran. It consists banded, nodular and disseminated magnetite hosted folded micaschists. Trace element Fe O isotopic experiments reveal various hydrothermal precipitation environments under reduced to slightly oxidizing conditions. Disseminated has high Ti (945–1940 ppm) positively correla...

The interpretation of low-temperature thermochronology (LTT) data in magmatic and metallogenic provinces requires a knowledge the geothermal field through time. There, challenge is differentiating rapid cooling following transient perturbations geotherms (reheating) from exhumational induced by erosion during tectonic uplift or normal faulting. Takab Range Complex (NW Iran) basement-cored range...

Background and Objective: Microbial and physicochemical properties of drinking water، considering type and quantity of drinking water, are factors for determining the acceptability of water. The effects of each of the above components on increasing the quality of water or threatening the health of consumers are also considerable. We aimed to investigate the trace amounts of microbial, physicoch...

Abstract Most conventional statistical methods aiming at defining geochemical concentration thresholds for separating anomalies from background have limited effectiveness in areas with complex geological settings and variable lithology. In this paper, median+2MAD as a method of exploratory data analysis (EDA) and concentration-area (C-A) fractal model as two effective approaches in separation g...

The Plio- Quaternary volcanoes are located in the NE-Qorveh (Kurdistan) in the Qorveh-Takab volcanic belt, in the Hamedan-Tabriz Zone (HTZ). The volcanic rocks consist of basalt to olivine-basalt. The electron microprobe (EMP) analyses of pyroxenes show occurrence of one type of clinopyroxene, as diopside (Fs 2.65-6.42 En 40.44-50.47 Wo45.97-53.14) with Mg # = 84-98. The compositions of the pyr...

The intrusive body of the Shahrak is located between the West Azarbaijan and Kurdistan provinces. Lithologically, this intrusive body consists of granodiorite, monzonite, monzodoirite and monzogobbro, which intruded into Oligo-Miocene sedimentary units and Cretaceous and Precambrian metamorphic rocks. Mineral chemistry studies of granodiorite and monzogabbro rocks show that plagioclases have la...
