مدل‌بندی ژیوشیمیایی فازهای کنترل‌کننده فراوانی عناصر اصلی و کمیاب در آمفیبولیت‌های میگماتیتی سه‌قلاتون، نیریز، ایران

The a-type granitoid of the east misho, are per-aluminous to sub-aluminous rocks that formed by partial melting of lower crust and including quartz, k-feldspar, plagioclase, amphibole and biotite and accessory minerals including alanite, zircon, apatite and fe-oxides. the ree normalized chondorite pattern of the granitoid show the m-type tetrad effect and strong eu depletion. all of petrography and geochemistry data show fractionation crystallization of ree-enriched minerals followed by magma-fluids reaction in late crystallization phenomena is the most important factor for the formed tetrad effect in the misho granitoid rocks.
