Tanbour metamorphic complex east of Sirjan is compoused of metasediments and metabasic rocks. Petrofabric study of this complex shows two metamorphic and two deformational phases. Chemical studies of index minerals indicate that second phase of metamorphism occurred with a degree up to lower amphibolite facies. Mineral assemblage of first phase are biotite, muscovite and garnet while staurolite...

Abstract In this contribution, we present the stratigraphy of igneous and metamorphic rocks Taquetren Range, a sector located in southernmost margin North Patagonian Massif (42°42′00″ S - 69°30′00″ W). Its basement is composed newly defined “Lagunita Salada Igneous-Metamorphic Complex” (LSIMC), “Paso del Sapo Plutonic (PSPC) “Sierra de (STPC). The LSIMC comprises gneisses, schists, amphibolites...
