Geology of Oman. The geology of Oman includes varied landscapes which are a blend of its geological history, and its climate over the past few million years. Rock outcrops in the Hajar, Huqf and Dhofar Mountains are a point of interest for international geologists. The rock record spans about 825 million years and includes at least three ...
Oman's geological record is extremely valuable to geologists, and needs to be preserved. [38] It contains the most complete ophiolite on Earth, of which it is most famous for among geologists. The ophiolite sequence has spectacular pillow basalt (Geotimes pillow lava), as well as exposures of the fossil crust-mantle boundary .
The land area is composed of varying topographic features: valleys and desert account for 82 percent of the land mass; mountain ranges, 15 percent; and the coastal plain, 3 percent. The sultanate is flanked by the Gulf of Oman, the Arabian Sea, and the Rub' al Khali (Empty Quarter) of Saudi Arabia, all of which contributed to Oman's isolation ...
The Samail Ophiolite, also known as the Semail Ophiolite, is a large, ancient geological formation in Oman and the United Arab Emirates in the Arabian Peninsula. [2] It is one of the world's largest and best-exposed segments of oceanic crust, made of volcanic rocks and ultramafic rocks from the Earth's upper mantle that was overthrust onto the ...
The subsurface Gharif Formation has been informally divided into 3 members (Lower, Middle and Upper) by geologists from Petroleum Development Oman.Though these members may be difficult to distinguish in certain localities due to rapid lateral facies changes, differential incision, salt movement or erosion, multiple studies have shown that these 3 members can be correlated on a regional scale.
The Jebel Akhdar Mountains (Arabic: ٱلْجَبَل ٱلْأَخْضَر, romanized: Al-Jabal Al-Akhḍar, lit. 'The Green Mountain') is a mountain range approximately 80 km (50 mi) long and 32 km (20 mi) wide, [2] that is part Hajar Mountains in Ad Dakhiliyah Governorate of Oman. It rises to a height of 3,018 m (9,902 ft) [1][3] and ...
The Rub' al Khali Basin (ٱلرُّبْع ٱلْخَالِي) or ar-Rubʻ al-Khālī / ar-rubʿ al-ḵālī Basin, Arabic for "Empty Quarter Basin", is a major endorheic sedimentary basin of approximately 560,000 square kilometres (220,000 sq mi) in southern Saudi Arabia, northeastern Yemen, southeastern Oman and southeasternmost United Arab ...
The Abu Mahara Group (c. 725–<645 Ma) is a geologic group of formations that are spread across northern Oman (Jabal Akhdar), east-central Oman (Huqf area), and southern Oman (Mirbat area of Dhofar). It belongs to the Huqf Supergroup. [1] [2] The group hosts two glacial successions in the Ghubrah and Fiq formations.
