RISBiostratigraphy and paleo-ecological reconstruction on Scleractinian reef corals of Rupelian-Chattian succession (Qom Formation) in northeast of Delijan area
In this research, biostratigraphy and paleo-ecological reconstruction of the Qom Formation deposits in Bijegan village, northeast of Delijan, are discussed. The studied section is situated in the western margin of the Urumieh-Dokhtar magmatic arc...
Geochemical constraints on the provenance of Oligocene– Miocene siliciclastic deposits (Zivah Formation) of NW Iran: implications for the tectonic evolution of the Caucasus
of paleo-weathering. Low to moderate values of the chemical index of alteration (mean CIA=53/68 for sandstones/shales) and relatively high values
of index of compositional variability (mean ICV=1.23/1.08 for sandstones/shales) suggest weak chemical...

Structure of the Millen Schist Belt (Antarctica): Clues for the tectonics of northern Victoria Land along the paleo Pacific margin of Gondwana
Final closure of the Paleo Asian Ocean along the Solonker Suture Zone: Constraints from geochronological and geochemical data of Permian volcanic and sedimentary rocks
Evidence from detrital chrome spinel chemistry for Paleo-Tethyan intra-oceanic island-arc provenance recorded in Triassic sandstones of the Nakhlak Group, Central Iran
that mafic-ultramafic rock assemblages with SSZ signatures were generated in the Paleo-Tethyan realm before their obduction as an ophiolite. By comparing data from the present study with results from previous work on the Triassic in Central Iran it is evident...
Zircon U-Pb geochronology, Sr-Nd isotope analyses, and petrogenetic study of the Dehnow diorite and Kuhsangi granodiorite (Paleo-Tethys), NE Iran
The Paleo-Tethys ocean opened in Silurian time, and its subduction under the Turan plate started in the Late Devonian. By Late Triassic time (225 Ma), no Paleo-Tethys crust remained on the surface of the Iranian plate. Subsequently, however...
Geochemical and geochronological evidence for a Middle Permian oceanic plateau fragment in the Paleo-Tethyan suture zone of NE Iran
The mafic–ultramafic Fariman complex in northeastern Iran has been interpreted as a Paleo-Tethyan ophiolitic fragment with
subduction- and plume-related characteristics as well as a basin deposit on an active continental margin. Contributing...
