Abstract The present paper discusses the geochemical affinities, origin and ages of Jurassic granitoids Sanandaj-Sirjan Zone (SaSZ) in eastern part Zagros Thrust Zone. A multidisciplinary, integrated approach was carried out using existing granitoid data (major, trace, rare earth element isotopes) knowledge regional geology (geodynamic metamorphic setting), coupled with geophysical (magnetic su...

Apatite minerals of I-type Zouzan granitoids and typical garnet-bearing S-type granites have been analyzed by electron microprobe to define trace element concentrations and compare them in different granites. Zouzan granites are composed of apatites with lower Fe, Mn, Na and HREE and higher REE and ∑REE relative to S-type ones. Trace elements abundances of apatite often vary with some parameter...

Different rock types (syenogranite, alkali feldspar granite and quartz syenite intruded by microgranite dikes veins) were investigated in the Nikeiba region Egypt. The main components of studied intrusive rocks, comprised granites syenite, are plagioclase, amphibole, biotite, K-feldspar different proportions. Ground gamma ray measurements show that syenogranite, have highest radioactivity (K, e...
