petrology, geochronology, geochemistry and petrogenesis of bajestan granitoids, north of ferdows, khorasan razvi province
introduction the investigated area is situated in the south west of the khorasan razavi province along the north west of the lut block. different types of metal ore bodies along with non-metal deposits have already been documented in the lut block (karimpour et al., 2008). most of the study area is covered with granitoid rocks. metamorphic rocks with unknown age are present in the north of the ...
متن کاملThe contorted New England Orogen (eastern Australia): New evidence from UPb geochronology of early Permian granitoids
[1] A series of sharp bends (oroclines) are recognized in the Paleozoic to early Mesozoic New England Orogen of eastern Australia. The exact geometry and origin of these bends is obscured by voluminous magmatism and is still debated. Here we present zircon U-Pb ages that confirm the lateral continuation of early Permian (296–288 Ma) granitoids and shed new light on the oroclinal structure. Orog...
متن کاملu-pb zircon geochronology, sr-nd isotope geochemistry, and petrogenesis of oxidant granitoids at keybarkuh, southwest of khaf
keybarkuh area is located 70 km southwest of khaf, khorasan razavi province. the study area is situated in northeastern lut block. the rock units in the area are paleozoic metamorphic rocks and cretaceous to tertiary subvolcanic intrusions intruded as dike, stock and batholith; their composition varies from granite to diorite. based on magnetic susceptibility, the intrusive rocks are divided in...
متن کاملGeochronology investigation of the Bahlul Daghi volcanic dome, north of Tabriz, by application of 40Ar/39Ar dating on biotite
Tabriz Basin has had extensive Cenozoic and Quaternary volcanic activity and lies in NW Iran within the collision zone of the Arabian and Eurasian plates. Formations in the region consist of siliciclastic rocks of the Miocene age (Upper red formation), along with younger dacite volcanic rocks. The Bahlul Daghi volcanic dome in the south of Spiran is variable in terms of the composition between ...
متن کاملEvaluating the geochemistry of Bam salt dome in Hormozgan Province, Iran
Evaluation of the geochemistry and hydrochemical quality of Bam salt dome located in southern Iran, was conducted in this study. Two composite samples from salt units were collected and analysed by XRD and XRF to determine their mineral and elemental compositions. Water samples were also collected from the only spring in the area and analysed for major anions, cations and some toxic elements. T...
