Biotite samples from different units of Boroujerd Granitoid Complex (BGC) of the Sanandaj-Sirjan Zone, western Iran, have beenanalyzed by electron microprobe for major elements. Biotite analyses from three units of quartzdiorite, granodiorite and monzograniteof BGC have their own distinct non-overlapping compositional fields in the annite – siderophyllite – phlogopite – eastonitequadrilateral (...

this experiment was laid out in order to evaluate the effects  of different biofertilizers on yield components of barley. the experiment was a factorial design with three replications. treatments were three nitrogen biofrtilizers (nitroksin, nitrokara and supernitroplass) and three phosphate  biofrtilizers (phosphate barvar2, biozarr and superplass) with control for them and yield components we...

the aligoodarz granitoid occurs in sanandaj-sirjan zone (ssz), western iran. tonalite, granodiorite and granite are the main rock types cropping out in the area. comparison of aligoodarz granitoid with dehno and boroujerd granitoids reveals several similarities in their chemical characteristics. thus, the above mentioned granitoids can be assigned as a co-genetic magmatic suite, in which pluton...

a experiment was lay out in order to evaluate the effects  of different biofertilizers on yield and yield components of maize at the lorestan provience, iran. the experiment was a factorial design with three replications. treatments were three nitrogen biofrtilizers (nitrokara (n1), o4 (n2), o6 (n3) and control (n4)) and three phosphate biofrtilizers (phosphate barvar2 (p1), biozarr (p2), mc1+p...

tourmalinization characterizes the most pervasive alteration type in the nezam abad ore deposit, west-central iran. it delineates high-temperature centers of mineralization and together with quartz and cassiterite form inner parts of the alteration halo. the composition of tourmalines plots mostly along and between the proton and alkali-deficient end members. tourmaline in quartzdioritic host i...

during recent years there has been increasing consciousness of, and concern about, groundwater water pollution and monitoring in iran. in this context, a comprehensive review of the trace elements and heavy metals in groundwater of oshtorinan plain in northern part of boroujerd has carried out to investigate the effects of weathering minerals, agricultural and industrial activities. groundwater...
