Depositional Environment and Sequence Stratigraphy of the Oligocene-Miocene Deposits North and East of Dehdasht, Izeh Zone, Zagros Basin, Iran
In this study, four well-exposed outcrops of the Asmari Fm in the southeastern part of the Izeh Zone of the Zagros Mountains were measured and sampled. In this region, the Asmari Fm is Oligocene to Early Miocene in age as determined by large benthic foraminifera. Based on depositional geometries, biogenic contents and lateral and vertical variations of facies, three depositional models are prop...
متن کاملEnvironmental Magnetic Record of the Eocene-Oligocene Transition in CRP-3 Drillcore, Victoria Land Basin, Antarctica
A 1500-m-thick Cenozoic sequence was recovered in a series of 3 drill holes from the Victoria Land Basin, Antarctica, in association with the Cape Roberts Project. The CRP-3 drill hole penetrated the oldest Palaeogene strata in the Granite Harbour region and terminated in strata from the Devonian Beacon Supergroup. The upper 823-m of the CRP-3 drill-core is an expanded sequence that may span th...

متن کاملOligocene stratigraphy across the Eocene and Miocene boundaries in the Valley of Lakes (Mongolia)
Cenozoic sediments of the Taatsiin Gol and TaatsiinTsagaan Nuur area are rich in fossils that provide unique evidence of mammal evolution in Mongolia. The strata are intercalated with basalt flows. 40Ar/39Ar data of the basalts frame the time of sediment deposition and mammal evolution and enable a composite age chronology for the studied area. We investigated 20 geological sections and 6 fossi...
متن کاملEocene-Oligocene volcanic units of momen abad, east of Iran: petrogenesis and magmatic evolution
This study investigates petrology and major, minor, and rare earth elements geochemistry of East Iranian Eocene–Oligocene volcanic rocks in Sistan suture zone, to examine their petrogenesis and magma evolution. The volcanic rocks include andesite, trachy-andesite, dacite and rhyolite. These calc-alkaline rocks of high-K series are enriched in Large Ion Lithophile Elements of Rb and Ba a...
