چکیده
The subsurface and surface structural geometries of the United Arab Emirates (UAE) fold-and-thrust belt (FTB) foreland basins are interpreted from seismic, well data, geology. Twelve horizons ranging in age Miocene to Lower Jurassic were mapped. Additionally, we outlined extent Sumeini Hawasina allochthonous nappes. tectonic subsidence curves suggest that final major passive margin rifting event occurred early Aalenian lasted till Oxfordian. Loading Semail ophiolite thrust sheet accompanying sheets resulted uplift at ca. 95 Ma rapid 83 Ma, indicating transition Arabian a rifted basin. region witnessed an accelerated during late Oligocene-Miocene, attributed initial collision Central Iran plates. Permian-Jurassic NW-SE oriented rift faults reactivated as Late Cretaceous obduction Oligocene-Miocene continental collision. Two different regimes identified FTB. northern regime is characterized by inversion with up 3,700 m throw, whereas southern has pop-up structure possible basement origin. Four west-verging east-dipping thrusts, which cross area, form fault-propagation folds dissect entire stratigraphy. Moreover, décollement, together inverted structures formed Jabal Hafit anticline backthrust structure.

It has been a decade since emergency medicine was recognized as a specialty in the United Arab Emirates (UAE). In this short time, emergency medicine has established itself and developed rapidly in the UAE. Large, well-equipped emergency departments (EDs) are usually located in government hospitals, some of which function as regional trauma centers. Most of the larger EDs are staffed with medic...
متن کاملHemoglobinopathies in the United Arab Emirates.
The use of modern DNA techniques enabled us to characterize and identify 44 distinct beta-thal mutations and nine alpha-thal genotypes in the UAE population. All of the beta-thal mutations were severe beta+ or beta0 types resulting in transfusion-dependent phenotypes. Furthermore, a large number of alphaT alleles in the alpha-thal carriers and in patients with Hb H disease, accentuate the impor...
