sr-nd isotopic characteristic, u-pb zircon geochronology, and petrogenesis of najmabad granodiorite batholith, eastern iran
the study area is located south of ghonabad in eastern iran. this area is situated between two major faults, darouneh to the north and dashtbyaz to the south. the movements of these faults cased major dislocation of this block. najmabad granodiorite to granite batholith is elongated trending east-west 2×8 km2. mineralization is associated with granite and monzonite. alteration zones are: propyl...
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 کاملpetrogenesis of granitoids, u-pb zircon geochronology, sr-nd petrogenesis of granitoids, u-pb zircon geochronology, sr-nd isotopic characteristics, and important occurrence of tertiary mineralization within the lut block, eastern iran
tertiary intrusive granitoids within the lut block in the khorasan razavi and south khorasan provinces are mainly sub-volcanic with porphyry texture and their composition varies from granite to diorite but monzonite is dominant. with the exception of hired, these are classified as belonging to the magnetite-series of i-type granitoids. chemically, these rocks are meta-aluminous. those with mine...
متن کاملgeology, mineralization, rb-sr & sm-nd geochemistry, and u–pb zircon geochronology of kalateh ahani cretaceous intrusive rocks, southeast gonabad
kalateh ahani is located 27 km southeast of gonabad within the khorasan razavi province. the area is part of lut block. sub-volcanic monzonitic rocks intruded regional metamorphosed shemshak formation (jurassic age). magnetic susceptibility of less altered monzonitic rocks is 0.6%., as, pb and zn > 1%, au up to 150 ppb and sn = 133 ppm. the sn content of vein in the northern part of kalateh aha...
متن کاملZircon U-Pb geochronology links the end-Triassic extinction with the Central Atlantic Magmatic Province.
The end-Triassic extinction is characterized by major losses in both terrestrial and marine diversity, setting the stage for dinosaurs to dominate Earth for the next 136 million years. Despite the approximate coincidence between this extinction and flood basalt volcanism, existing geochronologic dates have insufficient resolution to confirm eruptive rates required to induce major climate pertur...
