Abstarct: Due to consumption of the Neotethyan oceanic slab of the Sabzevar basin in the late Cretaceous- Paleocene subduction, the Sabzevar Cenozoic magmatic belt has been extensive magmatism especially in the Paleocene- Eocene times. The peak of this magmatism has been in the Middle- Late Eocene which associated with intrusion of abundant adakite domes in this belt. These adakite domes have intermediate-felsic rocks include andesite/ trachyandesite, diorite, dacite/ rhyodacite and rhyolite, showing propylitic, sericitic and argillitic alterations. Enrichment in light rare earth elements (LREEs) and large ion lithophile elements (LILEs) and depletion in heavy rare earth elements (HREEs) and high field strength elements (HFSEs) are obvious in their primitive mantle and chondrite normalized spidergrams. These characteristics combined with high Na_2O and Al_2O_3 and Sr contents, high Sr/Y and low K_2O/Na_2O ratios with depletion in HREEs, Y and HFSEs are similar to that ranges observed in the typical adakite rocks. The Sabazevar adakites include two types of high silica (HSA) and low silica (LSA) adakites. Petrological and geochemical data indicate that the magma forming of the HSA and LSA adakites originated from partial melting of the subducted and mextamorphosed oceanic slab of the Neo-Tethyan (Sabzevar–Darouneh branch), and it’s mextasomatized mantle wedge above it’s subduction zone in a continental margin subduction zone. The HSA usually has Cu-Au mineralization. Processing of data on the Sabzevar HSA along with the field observations indicate this type of mineralization in the region.
