Noghan granitoid intrusion is located at the NW of Boin- Miandasht and lies in the Sanandaj-Sirjan structural zone (SSZ). Based on field evidence and petrographic studies, the pluton is considered as two-mica granite that has been strongly affected by deformation and shows a good mylonitic foliation study area. The main minerals in the pluton are quartz, alkali feldspar (microcline and perthite...

Mesozoic granitic plutons are found throughout the Indochina terrane of eastern Cambodia and southern Vietnam. The rocks range in age from Early Triassic (240 Ma) to Late Cretaceous (80 record distinct tectonomagmatic periods associated with subduction Paleotethys Paleo-Pacific oceans. Samples collected Snoul pluton, composed silicic intermediate dioritic rocks, basalt. quartz diorites magnesia...

Abstract The Olds Ferry terrane is the more inboard of two accreted volcanic arc terranes in late Paleozoic–early Mesozoic Blue Mountains province northern U.S. Cordillera. We present geologic, geochronologic, and geochemical data from volcano-sedimentary Huntington Formation that place within a firm temporal tectonomagmatic context, establish its identity as fringing along Triassic to Early Ju...

Abstract Globally, the largest geothermal resources are linked to crystalline basement, which could be exploited using Enhanced Geothermal Systems (EGS). The planned underground laboratory GeoLaB aims facilitate large-scale application of EGS technologies by performing in-situ high-flowrate experiments on fault zones. Tromm Granite at northwestern margin Upper Rhine Graben was preselected as on...

Abstract The Neoproterozoic S-type granitic plutons, distributed along the suture zone of Yangtze and Cathaysia blocks, play an important role in tectonic evolution Jiangnan Orogeny. However, few studies had focused on scientific issues physical construction process these therefore, we carried out multidisciplinary approaches Sanfang Yuanbaoshan plutons western Jiangan Orogenic Belt to figure m...

Abstract Contrasting views exist in regard of the evolution metamorphic rocks southeastern Pohorje Mountains (Mts), located Eastern Alps. Major debated points are whether micaschists have experienced ultrahigh‐pressure metamorphism Late Cretaceous (Eo‐Alpine) and they were continuously exhumed or a multiple subduction–exhumation process from that time on. Therefore, we studied micaschist sample...
