The population growth and new housing is a ubiquitous feature of modern life in the developing and developed world alike land use changes in response to rising social, demographic and economic pressures. Inevitably, these new changes will have an impact on the environment around them. The aim of the study is the analysis of runoff and water quality...

Loess accumulation and paleosol formation are important Quaternary geoarchives in northern Iran. Two loess-paleosol sequences at Mobarakabad and Aghband were examined using soil morphology and micromorphology, mineralogy, magnetic susceptibility (MS), free Fe oxides and calcium carbonate equivalent. The loess-paleosol sequences provide a record of...

Full-text available
Constraining the controls on the distribution of sediment at a continental scale is a critical step in understanding long-term landscape and climate evolution. In particular, understanding of the role of rivers in wider sediment routing and impacts on aeolian loess formation on a continental scale remains limited. Extensive Quaternary loess deposit...
Article
Full-text available
Paleoclimatic investigation of loess-paleosol sequences from northern Iran is important for understanding past changes in a region highly sensitive to shifts in precipitation, and along potential routes of past human migration. Here, we present carbon and oxygen isotopic compositions of bulk carbonate (δ13Cbc and δ18Obc, respectively) coupled with...
Conference Paper
Full-text available
Loess deposits of northern and northeastern Iran provide excellent sedimentary archives for understanding past climate and environment changes in the continental interior. The loess records paleoenvironmental change in Iran over multiple glacial cycles, and helps to assess the extent to which key features of loess stratigraphy can be traced along t...
Article
The magnetic properties of the loess-paleosol sequences from northern Iran provides a model for understanding pedogenic processes and its relationship to paleo-precipitation in this region. For the first time, we present diffuse reflectance spectrophotometry (DRS) analyses, color measurement analyses, and temperature-dependent susceptibility (χ-T)...
Article
Full-text available
Central Asia (CA) is one of the main loess regions in the world and provides important information evidence for the understanding of paleoclimate and paleoenvironmental changes. However, the spatio-temporal variability of the loess distribution is still not fully understood. Combining previous studies with our recent field investigations, we focus...
Article
Stable carbon and oxygen isotope compositions in soil carbonates and in soil organic matter provide insights into (paleo) climatic conditions, especially in arid and semiarid regions where carbonate is abundant in soils. We here investigate δ13C and δ18O isotope composition of bulk carbonate, pedogenic carbonate nodules and organic carbon from mode...

Introduction: Loess deposits of Northern Iran provide excellent sedimentary archives for understanding past climate and environment changes in the continental interior. Diffuse reflectance spectroscopy (DRS) is a rapid and non-intrusive tool for characterizing soils and sediments and linking them to environmental processes. Balsam and Deaton (1991)...
Conference Paper
Full-text available
Investigations of loess-paleosol sequences from Northern Iran are important because this region is a key area between the European and Asian loess zones. Diffuse reflectance spectrophotometry (DRS) provides a (semi) quantitative method to determine mass concentrations of hematite (Hm) as low as ~0.01wt% in loess-paleosol sequences and also has...
Data
Paleoclimatic investigations on loess-paleosol sequences from northern Iran are important due to the specific location of this region, which may help to trace key features of loess stratigraphy along the Southern Eurasian loess belt. The oxygen and carbon isotopic composition of soil and other near surface carbonates is widely used in the geolo...
Data
Loess sediment in the mid-latitude of Eurasia provides an excellent sedimentary archive for understanding the past climate and environment changes in the continental interior. North Iran is a key site that connects Eu ropean and Asian loess zones. Optical dating is now well established as feasible means of establishing the age of loess deposits...

Project
In this project, we examine the loess units at the Chenarli section to locate the immediate source of loess and also to infer that if the loess units of our section most likely came from a similar source or not. Also, we use geochemical indices to compare the weathering intensity of the paleosols in the section.
Project
Here we will report on Rock magnetic and DRS of loess and paleosols samples of the Late Pleistocene loess-paleosol sequence at Chenrarli in northeastern Iran. This approach aims at focusing on identifying iron oxides of the samples in order to obtain more detailed information about the interaction between climate factors, seasonality of rainfall and temperature, pedogenesis process, and magnetic signals of the loess-paleosol sequence in northeastern Iran.
Project
Loess Eurasian Development ESR (LEADER) network's main goal is to bring together young loess scholars from many Eurasian countries for the first time and provide them opportunities for more intensive development of their research skills and general knowledge. Many quaternary research communities in countries of the Eurasian loess belt are traditionally isolated and have very little or no intention to promote ESR. However, in some European and Asian countries, there is already a long tradition of research collaboration and exchange of experiences between different investigation groups including ESR mobility. The LEADER network initiative has a clear goal to improve international collaboration of ERS making joint field and laboratory investigations. Thus, the establishment of the LEADER network can be regarded as a great opportunity for future intensification of loess research across the huge Eurasian loess belt.
