Rub' Al Khali Basin
The Rub' al Khali Basin () or / Basin, Arabic language, Arabic for "Empty Quarter Basin", is a major endorheic basins, endorheic sedimentary basin of approximately in southern Saudi Arabia, northeastern Yemen, southeastern Oman and southeasternmost United Arab Emirates. The wikt:onshore, onshore foreland basin, foreland on Mesozoic rift basin is geographically defined by the wikt:eponymous, eponymous Rub' al Khali and covers the regions of Saudi Arabia, regions of Najran Region, Najran and Riyadh Region, Riyadh and the Eastern Province, Saudi Arabia, Eastern Province. The basin is geologically bound by the Central Arabian Arch in the north, the Oman Thrust in the east, the Northern Hadramaut Arch in the south, and the Arabian Shield in the west. Politically, the southwestern boundary is formed by the border with Yemen and the border with Oman forms the southeastern boundary. The stratigraphy of the basin ranges from Proterozoic to recent and comprises various cycles of clastic a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arabic Language
Arabic (, ' ; , ' or ) is a Semitic language spoken primarily across the Arab world.Semitic languages: an international handbook / edited by Stefan Weninger; in collaboration with Geoffrey Khan, Michael P. Streck, Janet C. E.Watson; Walter de Gruyter GmbH & Co. KG, Berlin/Boston, 2011. Having emerged in the 1st century, it is named after the Arab people; the term "Arab" was initially used to describe those living in the Arabian Peninsula, as perceived by geographers from ancient Greece. Since the 7th century, Arabic has been characterized by diglossia, with an opposition between a standard prestige language—i.e., Literary Arabic: Modern Standard Arabic (MSA) or Classical Arabic—and diverse vernacular varieties, which serve as mother tongues. Colloquial dialects vary significantly from MSA, impeding mutual intelligibility. MSA is only acquired through formal education and is not spoken natively. It is the language of literature, official documents, and formal written m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hercynian Orogeny
The Variscan or Hercynian orogeny was a geologic mountain-building event caused by Late Paleozoic continental collision between Euramerica (Laurussia) and Gondwana to form the supercontinent of Pangaea. Nomenclature The name ''Variscan'', comes from the Medieval Latin name for the district '' Variscia'', the home of a Germanic tribe, the Varisci; Eduard Suess, professor of geology at the University of Vienna, coined the term in 1880. (Variscite, a rare green mineral first discovered in the Vogtland district of Saxony in Germany, which is in the Variscan belt, has the same etymology.) ''Hercynian'', on the other hand, derives from the Hercynian Forest. Both words were descriptive terms of strike directions observed by geologists in the field, ''variscan'' for southwest to northeast, ''hercynian'' for northwest to southeast. The ''variscan'' direction reflected the direction of ancient fold belts cropping out throughout Germany and adjacent countries and the meaning shifted from d ...

Saudi Arabia
Saudi Arabia, officially the Kingdom of Saudi Arabia (KSA), is a country in Western Asia. It covers the bulk of the Arabian Peninsula, and has a land area of about , making it the fifth-largest country in Asia, the second-largest in the Arab world, and the largest in Western Asia and the Middle East. It is bordered by the Red Sea to the west; Jordan, Iraq, and Kuwait to the north; the Persian Gulf, Qatar and the United Arab Emirates to the east; Oman to the southeast; and Yemen to the south. Bahrain is an island country off the east coast. The Gulf of Aqaba in the northwest separates Saudi Arabia from Egypt. Saudi Arabia is the only country with a coastline along both the Red Sea and the Persian Gulf, and most of its terrain consists of arid desert, lowland, steppe, and mountains. Its capital and largest city is Riyadh. The country is home to Mecca and Medina, the two holiest cities in Islam. Pre-Islamic Arabia, the territory that constitutes modern-day Saudi Ar ...

Sedimentary Basin
Sedimentary basins are region-scale depressions of the Earth's crust where subsidence has occurred and a thick sequence of sediments have accumulated to form a large three-dimensional body of sedimentary rock. They form when long-term subsidence creates a regional depression that provides Accommodation (geology), accommodation space for accumulation of sediments. Over millions or tens or hundreds of millions of years the deposition of sediment, primarily gravity-driven transportation of water-borne eroded material, acts to fill the depression. As the sediments are buried, they are subject to increasing pressure and begin the processes of compaction (geology), compaction and lithification that transform them into sedimentary rock. Sedimentary basins are created by deformation of Earth's lithosphere in diverse geological settings, usually as a result of plate tectonics, plate tectonic activity. Mechanisms of crustal deformation that lead to subsidence and sedimentary basin formati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endorheic Basins
An endorheic basin (; also spelled endoreic basin or endorreic basin) is a drainage basin that normally retains water and allows no outflow to other external bodies of water, such as rivers or oceans, but drainage converges instead into lakes or swamps, permanent or seasonal, that equilibrate through evaporation. They are also called closed or terminal basins, internal drainage systems, or simply basins. Endorheic regions contrast with exorheic regions. Endorheic water bodies include some of the largest lakes in the world, such as the Caspian Sea, the world's largest inland body of water. Basins with subsurface outflows which eventually lead to the ocean are generally not considered endorheic; they are cryptorheic. Endorheic basins constitute local base levels, defining a limit of erosion and deposition processes of nearby areas. Etymology The term was borrowed from French ''endor(rh)éisme'', coined from the combining form ''endo-'' (from grc, ἔνδον ''éndon'' 'withi ...

Dibba Transform Fault
Dibbā ( ar, دِبَّا) is a coastal area at the northern tip of the eastern Arabian peninsula on the Gulf of Oman. Political administration Dibba is politically divided into three segments: * Dibba Al-Fujairah, ruled by the Emirate of Fujairah, UAE * Dibba Al-Hisn, ruled by the Emirate of Sharjah, UAE * Dibba Al-Baya, ruled by the Governorate of Musandam, Oman History This large natural harbor on the east coast of the northern Emirates has been an important site of maritime trade and settlement for millennia, with relatively recent excavations underpinning the importance of the town as a site of entrepot trade throughout the Iron Age and into the late pre-Islamic era. A collective tomb, discovered by accident in 2004, led to a number of excavations in the area of the present town which have yielded evidence of a large settlement with layers of occupation and significant finds of trade goods, bitumen, ceramics and glass as well as coins.

Najd Fault System
Najd ( ar, نَجْدٌ, ), or the Nejd, forms the geographic center of Saudi Arabia, accounting for about a third of the country's modern population and, since the Emirate of Diriyah, acting as the base for all unification campaigns by the House of Saud to bring Arabia under a single polity and under the Salafi jurisprudence. Historic Najd was divided into three modern administrative regions still in use today. The Riyadh region, featuring Wadi Hanifa and the Tuwaiq escarpment, which houses easterly Yamama with the Saudi capital, Riyadh since 1824, and the Sudairi region, which has its capital in Majmaah. The second administrative unit, Al-Qassim, houses the fertile oases and date palm orchards spread out in the region's highlands along Wadi Rummah in central Najd with its capital in Buraidah, the second largest Najdi city, with the region historically contested by the House of Rashid to its north and the House of Saud to its east and south. The third administrative uni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ramlah Field
Ramla or Ramle ( he, רַמְלָה, ''Ramlā''; ar, الرملة, ''ar-Ramleh'') is a city in the Central District of Israel. Today, Ramle is one of Israel's mixed cities, with both a significant Jewish and Arab populations. The city was founded in the early 8th century CE by the Umayyad prince Sulayman ibn Abd al-Malik as the capital of Jund Filastin, the district he governed in Bilad al-Sham before becoming caliph in 715. The city's strategic and economic value derived from its location at the intersection of the '' Via Maris'', connecting Cairo with Damascus, and the road connecting the Mediterranean port of Jaffa with Jerusalem. It rapidly overshadowed the adjacent city of Lydda, whose inhabitants were relocated to the new city. Not long after its establishment, Ramla developed as the commercial centre of Palestine, serving as a hub for pottery, dyeing, weaving, and olive oil, and as the home of numerous Muslim scholars. Its prosperity was lauded by geographers in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stratigraphy
Stratigraphy is a branch of geology concerned with the study of rock (geology), rock layers (Stratum, strata) and layering (stratification). It is primarily used in the study of sedimentary rock, sedimentary and layered volcanic rocks. Stratigraphy has three related subfields: lithostratigraphy (lithologic stratigraphy), biostratigraphy (biologic stratigraphy), and chronostratigraphy (stratigraphy by age). Historical development Catholic priest Nicholas Steno established the theoretical basis for stratigraphy when he introduced the law of superposition, the principle of original horizontality and the principle of lateral continuity in a 1669 work on the fossilization of organic remains in layers of sediment. The first practical large-scale application of stratigraphy was by William Smith (geologist), William Smith in the 1790s and early 19th century. Known as the "Father of English geology", Smith recognized the significance of Stratum, strata or rock layering and the importance ...

Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present.
