Tuwaiq Escarpment
Jabal Tuwaiq ( ar, جَبَل طُوَيْق, Tuwaiq Mountain) is a narrow escarpment that cuts through the plateau of Najd in central Arabia, running approximately from the southern border of Al-Qasim in the north, to the northern edge of the Empty Quarter desert near Wadi ad-Dawasir in the south. It is high and also has a Middle Jurassic stratigraphic section. The eastern side slopes downwards gradually, while the western side ends in an abrupt manner. The escarpment can be thought of as a narrow plateau, though the locals refer to it as a ''jebel'' ("mount"). Marshall Cavendish used the name "Tuwayr Mountains" to describe mountains of central Arabia, distinct from the Shammar in the north, the Dhofar in the south, and the Hajar to the east. Many narrow valleys (''wadis'') run along its sides, such as Wadi Hanifa, and a group of towns lie on its central section, including the Saudi capital, Riyadh. Many settlements have historically existed on either side of it as well, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Highway 40 (Saudi Arabia)
Highway 40 () is a major east–west six-lane controlled-access highway in Saudi Arabia, spanning 1,395 km (867 mi). The highway connects Jeddah, the second-largest city in the kingdom, on the western coast of Saudi Arabia to Dammam, the sixth-largest city on the eastern coast and the largest in the Eastern Province. Apart from Jeddah and Dammam, Highway 40 also runs near or through Mecca, Ta'if, Riyadh, Abqaiq and Khobar along its length, and provides access to the Mahazat as-Sayd and Saja and Umm Al Ramth wildlife sanctuaries. The highway consists of three traffic lanes and an emergency lane on each side (a total of six traffic lanes and eight total lanes) separated by a median strip. All intersections of the highway are grade separated. The route traverses the mostly flat Najd plateau, and thus requires no bridges or tunnels for most of its length. Near the western part, the highway twists and turns around the Hejaz mountains, before reaching the western coastal plain. Several ...

Petroleum Reservoir
A petroleum reservoir or oil and gas reservoir is a subsurface accumulation of hydrocarbons contained in porous or fractured rock formations. Such reservoirs form when kerogen (ancient plant matter) is created in surrounding rock by the presence of high heat and pressure in the Earth's crust. Petroleum reservoirs are broadly classified as ''conventional'' and '' unconventional'' reservoirs. In conventional reservoirs, the naturally occurring hydrocarbons, such as crude oil or natural gas, are trapped by overlying rock formations with lower permeability, while in unconventional reservoirs, the rocks have high porosity and low permeability, which keeps the hydrocarbons trapped in place, therefore not requiring a cap rock. Reservoirs are found using hydrocarbon exploration methods. Oil field An oil field is an area of accumulation of liquid oil underground in multiple (potentially linked) reservoirs, trapped as it rises by impermeable rock formations. In industrial terms, a ...

Upper Jurassic
The Late Jurassic is the third epoch of the Jurassic Period, and it spans the geologic time from 163.5 ± 1.0 to 145.0 ± 0.8 million years ago (Ma), which is preserved in Upper Jurassic strata.Owen 1987. In European lithostratigraphy, the name "Malm" indicates rocks of Late Jurassic age. In the past, ''Malm'' was also used to indicate the unit of geological time, but this usage is now discouraged to make a clear distinction between lithostratigraphic and geochronologic/chronostratigraphic units. Subdivisions The Late Jurassic is divided into three ages, which correspond with the three (faunal) stages of Upper Jurassic rock: Paleogeography During the Late Jurassic Epoch, Pangaea broke up into two supercontinents, Laurasia to the north, and Gondwana to the south. The result of this break-up was the spawning of the Atlantic Ocean. However, at this time, the Atlantic Ocean was relatively narrow. Life forms of the epoch This epoch is well known for many famous types of dinosau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sudair
Sudair or Sudayr ( ar, سدير) is a historical region in Najd in the central of Saudi Arabia, and is located approximately 150 km north of the Saudi capital, Riyadh. The region lies in a valley directly to the east of the Tweig escarpment, which runs across Najd starting from Sudair in the north and ending near Wadi ad-Dawasir in the south. Before the modern era, the region, like most others in Najd, depended on the valley's ability to retain rainwater, and its people mainly subsisted on the cultivation of grains and dates. Families of farmers were ruled by local Emirs in their various settlements around Sudair before the modern era. The local variety of dates in Sudair is known as ''kudry'', and is darker in color and has a stronger flavor than other varieties of dates grown in the country. Graded as low quality locally due to its commonality, the ''kudry'' is highly prized abroad and around other regions of Arabia. Sudair's towns and villages include Harmah, Al Majma ...
