Abstract Metabasic rocks of the ophiolitic sequences Glockner Nappe and Eclogite Zone in south-central Tauern Window, Austria, reveal important insights into rifting spreading Alpine Tethys. U–Pb dating magmatic zircons yields a concordant 157 ± 2 Ma crystallization age for precursor coarse-grained metagabbro from Nappe. The Late Jurassic intrusion is coeval with mafic plutonic activity Western...

Lawsonite eclogites represent fossil records of processes occurring during subduction of cold and fast-subducting slabs, and provide the opportunity to investigate the thermal and metamorphic evolution of palaeosubduction zones. Occurrences of lawsonite eclogites are rare because lawsonite is often replaced during exhumation. We report here, for the first time, the occurrence of a lawsonite ecl...

The corundum is found in the rocks of Berit metaophiolite Eastern Anatolia, near Doğanşehir a province Malatya. Metaophiolitic consist mainly garnet metagabbro, granulite, amphibolite, mylonitic amphibole schist, pyroxenite, orthopyroxenite, harzburgite, serpentinized dunite and diorite units. Corundum occurrences are mostly pyroxenites, amphibolites, peridotites granulites. Their colors change...

The Ciletuh Mélange Complex in West Java, Indonesia, provides evidence of early Cenozoic subduction. This study aims to investigate the stratigraphic position, geological structure, metamorphic facies, and protoliths rock units. research methods employed mapping, petrology, geochemical analysis. samples collected exhibit different including zeolites, greenschist, epidote amphibolite. Protoliths...

We present a detailed description of the tectono-stratigraphic architecture eclogite-facies Internal Piedmont Zone (IPZ) metaophiolite, exposed in Lanzo Valleys (Western Alps), which represents remnant Jurassic Alpine Tethys. Seafloor spreading and mantle exhumation processes related to Tethys evolution strongly conditioned intra-oceanic depositional setting, resulted an articulated physiograph...
