introduction the nabar area that is a part of the urumieh- dokhtar volcano- plutonic belt is located in the south of kashan. research works such as emami (emami, 1993) and abbasi (abbasi, 2012) have been done about the geology of this area. rock units in the study area contain middle- upper eocene intermediate to acidic lavas and pyroclastic rocks, green marl, shale and sandy marls of oligo- mi...

Abstract Crustal temperature conditions can strongly influence the evolution of deformation during orogenesis. The Sevier hinterland plateau in Nevada and western Utah (“Nevadaplano”) experienced a Late Cretaceous episode shallow-crustal metamorphism granitic magmatism. Here, we investigate thermal history Nevadaplano by measuring peak field gradients attained upper 10–20 km crust along an east...

Structural analysis of quartz vein systems and fluid inclusion criteria were used to distinguish five different fluid types which flowed through a segment of Palaeozoic crust in southwest England during the Variscan orogeny. Mineralogical constraints in combination with fluid inclusion thermobarometry enabled the temperature of vein formation to be estimated, and isotopic compositions of fluids...

Abstract. The transition processes from monogenetic volcanoes to composite are poorly understood. Late Pleistocene Holocene intraplate Wulanhada Volcanic Field (WVF) in northern China provides a snapshot of such transition. Here we present petrographic observations, mineral chemistry, bulk rock major and trace element data, thermobarometry, partial melting model for the WVF evaluate lithology d...
