Paleoecological changes in the Northeastern Iran, signals from carbon isotopic composition of pedogenic carbonates in loess derived soils
Stable isotopes in pedogenic carbonates can provide information for geomorphic
evolution of landscapes, past atmospheric CO2 partial pressure fluctuations,
paleotemperatures and local and global vegetation changes. Loess...
Calcic soils as indicators of profound Quaternary climate change in eastern Isfahan, Iran
of pedogenic carbonates in soils of differing ages is suggestive of a decrease in plant density and an increase in evaporation as soils become younger. This research highlights the utility of the morphology and isotope chemistry of calcic soils for constraining...
Stable isotope record in pedogenic carbonates in northeast Iran: Implications for Early Cretaceous (Berriasian–Barremian) paleovegetation and paleoatmospheric P(CO2) levels
The Shurijeh Formation (Early Cretaceous) consists of siliciclastic, evaporate, and carbonate facieswith associated calcareous paleosols in the Kopet-Dagh basin. These calcareous paleosols (pedogenic carbonate nodules) include specific...
