Stable isotope geochemistry of pedogenic carbonates in loess-derived soils of northeastern Iran: Paleoenvironmental implications and correlation across Eurasia
Despite the occurrence of pedogenic carbonates in loess/paleosol sequences of northern and northeastern Iran, there is no information about stable isotope geochemistry of pedogenic carbonates in these regions. This paper ...
Holocene hydrological changes in SE Iran, a key region between Indian Summer Monsoon and Mediterranean winter precipitation zones, as revealed from a lacustrine sequence from Lake Hamoun
Core sediments from dry lake bed of Hamoun, were subdivided into 3 main sedimentary units using a multi-proxy approach (e.g. petrography, grain size analysis, TOM% and CaCO3% determination) to reconstruct the palaeoenvironmet ...
Paleoenvironment of geomorphic surfaces of an alluvial fan in the eastern Isfahan, Iran, in the light of micromorphology and clay mineralogy
Alluvial fans are one of the most important landforms in geomorphological and paloenvironmental studies.
The objective of this study was the application of claymineral assemblages and micromorphological properties ...
Nannostratigraphy, nannofossil events, and paleoclimate fluctuations in the lower boundary of Kalat formation in East Kopet Dagh (NE Iran)
Abstract The biostratigraphy and the response of calcareous nannofossils to the End Cretaceous warming are investigated in the lower boundary of Kalat formation through the record of species richness, diversity, distribution ...
Geochemistry of Carboniferous shales of the Sardar Formation, east central Iran: Implication for provenance, paleoclimate and paleo-oxygenation conditions at a passive continental margin
The Sardar Formation (Carboniferous) has a lithological variation that is characterized by sandstone, shale and limestone members. Shales of the Sardar Formation from the east central Iran have been analyzes for major ...
