Abstract: 

The southwest Salmas metamorphosed mafic-intermediate intrusive rocks are located in Sanandaj-Sirjan zone in NW of Iran. The metamorphosed intrusives rocks comprisemetagabbro and metadiorite that intruded the Precambrian metamorphosed volcanicsedimentary rocks. U-Pb zircon dating of two samples of metagabbro rocks yielded age of Ca. 548.7±2.5 Ma to 553.1±7.0 Ma and one sample of metadiorite rock yielded age of 542±6.5 Ma (late Neoproterozoic-Cambrian). Based on the obtained geochemical results, these rocks were crystallized from subduction-related melts.The ef (t) values of these rocks are variable from+6.2 to+14.16. Hf model ages of mafic-intermediate rocks from the SW Salmas show values of 593-1000 Ma (Neoproterozoic). U-Pb zircon dating and Hf isotope results indicate that late Neoproterozoic-Cambrian metamorphosed mafic-intermediate intrusive rocks in the northwest of Iran were related to widespread magmatism (Cadomian magmatism) along the northern margin of Gondwana.
