| چکیده | ||
| The Sanandaj-Sirjan Zone is mainly composed of metamorphic complexes and granitic intrusions. These bodies are exposed and covered wide area of the Northern part of the zone. They are high potassium calk-alkaline felsic rocks and based on their Chondrite-normalized rare earth elements (REE) patterns, the LREE are enriched relative to HREE. The volcanic arc and within plate are the main tectonic environment of granite. The granitoids age of the Northern part of Sanandaj-Sirjan Zone are classified into three classes of Paleozoic, Middle Jurassic and Tertiary. The Sr-Nd isotopic ratios indicate a significant contribution of isotopically evolved components (older sedimentary material). | ||
