The Euphrates Plain (EP) experiences large interannual variability in vegetation cover, especially in areas of marginal rain-fed agriculture. Vegetation in this region is primarily limited by available soil moisture, as determined by winter precipitation, spring precipitation, and air temperature. Satellite analyses indicate that the springtime normalized difference vegetation index (NDVI) is n...
The aim of this work is to propose a first-order estimate of the crustal and lithospheric mantle geometry of the Arabia–Eurasia collision zone and to separate the measured Bouguer anomaly into its regional and local components. The crustal and lithospheric mantle structure is calculated from the geoid height and elevation data combined with thermal analysis. Our results show that Moho depth var...
Abstract The Zagros Mountains represent a strategic geographic region near the junction of Africa, Europe, and Asia, valleys within mountain range likely correspond to migration corridors used by archaic modern humans. Ghar-e Boof, key archeological site in southern Zagros, is located at an altitude 905 m.a.s.l. Dasht-e Rostam Fars Province, Iran. On basis lithic artifacts radiocarbon luminesce...
Quantified balanced and restored crustal cross-sections across the NW Zagros Mountains are presented in this work integrating geological and geophysical local and global datasets. The balanced crustal cross-section reproduces the surficial folding and thrusting of the thick cover succession, including the near top of the Sarvak Formation (∼ 90 Ma) that forms the top of the restored crustal cros...
We sequenced Early Neolithic genomes from the Zagros region of Iran (eastern Fertile Crescent), where some of the earliest evidence for farming is found, and identify a previously uncharacterized population that is neither ancestral to the first European farmers nor has contributed substantially to the ancestry of modern Europeans. These people are estimated to have separated from Early Neolith...

We use interferometric synthetic aperture radar observations to investigate the fault geometry and afterslip evolution within 3 years after a mainshock. The postseismic favor ramp-flat structure in which flat angle should be lower than 10°. deformation is dominated by afterslip, while viscoelastic response negligible. A multisegment, stress-driven model (hereafter called SA-2 model) with depth-...
Balanced cross-sections across the Zagros fold–thrust belt in Iran are used to analyze the geometry of deformation within the sedimentary cover rocks, and to test the hypothesis of basement involved thrusting throughout the fold–thrust belt. Although the Zagros deformation front is a relatively rectilinear feature, the sinuous map-view morphology of the mountain front is a result of a 6 km stru...
The goal of the Stratigraphy project of the STRATAFORM program is to understand the creation of the preserved stratigraphic record on continental shelves and slopes as the product of physical processes acting with spatial and temporal heterogeneities. I am using numerical models to provide insight into the formation and preservation of stratigraphic sequences at margins. My goal is to obtain a ...
