The Open Geology Journal , 2014, 8: 1-2. Fragments of Late Proterozoic ocean crust and mantle (ophiolites) occur within six major fault zones that mark sutures between crustal blocks (microplates) that were accreted between about 630 and 715 Ma to form the Arabian Shield. 10, pp. Geographically - and from north to south - the ANS includes the nations of Israel, Jordan. Zakaria Hamimi, Yahia El-Kazzaz, Khairiya Fawzy, Ezzat Abdelrahman, Mohamed El-Shafei , … This study is oriented to identify the geothermal potential of Harrat Rahat. Introduction . Arabian Shield seeks to provide a healthy environment and guarantees the right of insured to receive full treatment and health care he needs through a wide and distinctive network of hospitals. During this initial phase of the RGP, the SGS will focus on surveying and mapping some 600 000 km2 of the mineral-rich Arabian Shield area in western Saudi Arabia over the next 6 years, in a bid to better understand the existence and distribution of mineral resources in that area and provide a valuable database of geological knowledge to future mining investors and operators. aSaudi Geological Survey, PO Box 54141, Jiddah 21514, Saudi Arabia bGeology Department, King Saud University, PO Box 2009, Riyadh, Saudi Arabia Ophiolites make up a small but tectonically important part of the Arabian shield. In, Short Course on Hydrocarbon Exploration, KFUPM Press, Dhahran, 12p. Fig. (df) Plotting of Rs vs. v2 illustrating how the best-fit parameters (v2) of h-distribution text varies with strain (Rs) in the Hammamat Group exposed at Wadi Allaqi. DOI: 10.3133/PP560A Corpus ID: 131737883. January 2021. ; Jāmiʻat al-Malik ʻAbd al-ʻAzīz. 1290-1319. He used all these fields to study key areas in the Arabian-Nubian Shield and to decipher their deformation history. Pages 1-81 . Arabian Shield offers a strong potential for geothermal energy. Evolution and mineralization of the Arabian-Nubian Shield : proceedings of a symposium. American Association Petroleum Geologists, Bulletin 43, 434-454. Secondary aquifers. Arabian American Oil Company 1959. Arabian Shield granitic zircon geochemistry provides insight into the petrogenetic processes involved in generating one of the planet’s largest tracts of juvenile Neoproterozoic crust. The Video (16 minutes) is a very short introduction to the geology of the Arabian-Nubian Shield (the Arabic language). The lithosphere of the Arabian–Nubian shield was mainly formed during an interval of about 150 million years near the end of the Proterozoic aeon. Published by permission of Arabian American Oil Company. However, only a limited amount of exploration effort has taken place. These divergent interpretations have distinct hazard implications and highlight the importance of large survey aperture and anisotropic modeling to MT studies of volcanic regions. Editorial: Geology and Tectonic Setting of the Arabian-Nubian Shield. assemblage (immature arc or oceanic plateau) of the southwestern Arabian Shield (Baish group), acquired with the single-grain evaporation technique, yielded a mean 207 Pb/ 206 Pb age of 842 ±17 Ma.

The northern Arabian platform appears to be a composite plate similar up to that interpreted in the rocks of the Arabian shield. 29. Arabia: Saudi Arabian Deputy Ministry for Mineral Resources, Open-File Report, DGMR-OF-03-28, 45p. (ac) Rf/u plots (after Lisle, 1985) showing the strain ratios of the deformed pebbles of the Hammamat Group exposed at Wadi Allaqi. The geological map of the Arabian Plate illustrates that divergent margins are forming in the spreading centers of Red Sea and Gulf of Aden to the west and southwest of the Arabian Plate. Trace analyses of lineaments from satellite images are used in different geological fields to define and delineate geological structures, for example, mineral and petroleum exploration and hydrogeological modelling (Hariri & Abdullatif, 2005). The Arabian-Nubian Shield (ANS) is an exposure of Precambrian crystalline rocks on the flanks of the Red Sea.The crystalline rocks are mostly Neoproterozoic in age. The Arabian Shield was formed by successive accretions of newly formed crust between 1,000 and 600 Ma ago. Subproject 4.1.1.1.6 — Compilation and updating of the Arabian shield digital map. Journal of King Saud University - Science 33 (1):101266. Product names used in this report are for descriptive purposes and in no way imply endorsement by SGS. Where most complete, they consist of serpentinized peridotite, gabbro, dike complex, basalt, and pelagic rocks. The South and southeast of the Arabian plate is bounded by the Owen-Sheba intra-oceanic transform fault. The Arabian shield rocks are present in two subunits: 1) lower metamorphosed basic volcanic and the intercalated volcaniclastics (Figure 4(A)).This unit is present in the southern part of Wadi Qudaid and, 2) Acidic volcanic and the intercalated marble deposits which are present in the central and northern (upstream) part of Wadi Qudaid. Tectonics of the Eastern Desert of Egypt: Key to Understanding the Neoproterozoic Evolution of the Arabian–Nubian Shield (East African Orogen) Z. Hamimi, M. A. Abd El-Wahed, H. A. Gahlan, S. Z. Kamh. Zakaria Hamimi is the President and one of the founding teams, of the Arabian Geosciences Union since 2012. Arabian Platform. This represents a extensive … West of Bishah, the volcanic-plutonic crust had consolidated against Africa by about 780 Ma ago when westward-directed subduction ceased at the Nabitah suture. Figure 1 (from Bierlein 2016; modified after Kroner et al, 1987) The Arabian-Nubian Shield (Figure 1) comprises a collage of micro-terranes and arc belts, accreted together before becoming amalgamated with the Sahara metacraton during the end- Neoproterozoic Pan African collision between West and East Gondwana. Synthesis of available geological and geophysical data in the Syrian Arab Republic permits a descriptive account of the pre-Cenozoic geologic history of the northern Arabian platform. Successively younger island arcs formed to the East as West-dipping subduction zones shifted eastward. [Ahmed M al Shanti; Jāmiʻat al-Malik ʻAbd al-ʻAzīz. read more; image/svg+xml. The item Geology of the Arabian Peninsula western shield area, by G.F. Brown, D.L. Organized into four parts encompassing 15 chapters, this volume begins with an overview of the study of the geology of the western Saudi Arabia. Kullīyat ʻUlūm al-Arḍ. The Arabian Nubian Shield (ANS) This geological terrane covers a large portion of Northeast Africa and the Arabian Peninsula, and represents an assemblage of well-preserved subduction-related litho-tectonic blocks, accreted juvenile arc terranes, volcano-sedimentary basins, micro-continental terranes, and syn- to post-tectonic intrusions that formed between 800-650 Ma.
