Abstract

Pir-abad amphibolotes in the northest Azna locates SANANDAJ- SIRJAN ZONE. The AMPHIBOLITEs show a discontinuous outcrops as pods and lenses. Sometimes have lineation and foliation. Amphibole and plagioclase are main mineral constituents in the rocks. The AMPHIBOLITEs have igneous source. Their protholite is basalt with sub-alkaline and tholeiitic nature. Chondrite normalized-REE diagram show LREE enrichment relatetoon to HREE. Primitive mantle- normalized trace elements diagram show depletion of HFSE and HREE. Tectonic discrimination diagrams, negative Nb-Ta anomalies and high Th and Ba/Yb display the back-arc basin setting or supra-subduction zone environment.
