Jebel Arkenu
Mount Arkanu or Jabal Arkanu (also Jebel Arkenu or Gebel Árchenu) is a mountain in Libya. Geography The mountain is located in the Libyan Desert in the Kufra District of Libya, about 300 km southeast of El Tag.Bertarelli (1929), p. 515 and about 70 km west of Arkanu and the two Arkenu structures. Its height is , rising about 500 m above the surrounding Gilf Kebir plateau and a valley- oasis. Mount Arkanu is long and wide. Google Earth Arkanu's existence has been known since 1892 through Arab sources. Arkanu was first discovered in 1923 by Ahmed Hassanein. The mountain consists of intrusive granite Granite () is a coarse-grained ( phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase.

Libya
Libya (; ar, ليبيا, Lībiyā), officially the State of Libya ( ar, دولة ليبيا, Dawlat Lībiyā), is a country in the Maghreb region in North Africa. It is bordered by the Mediterranean Sea to the north, Egypt to the east, Sudan to the southeast, Chad to the south, Niger to the southwest, Algeria to the west, and Tunisia to the northwest. Libya is made of three historical regions: Tripolitania, Fezzan, and Cyrenaica. With an area of almost 700,000 square miles (1.8 million km2), it is the fourth-largest country in Africa and the Arab world, and the 16th-largest in the world. Libya has the 10th-largest proven oil reserves in the world. The largest city and capital, Tripoli, is located in western Libya and contains over three million of Libya's seven million people. Libya has been inhabited by Berbers since the late Bronze Age as descendants from Iberomaurusian and Capsian cultures. In ancient times, the Phoenicians established city-states and tradin ...

Libyan Desert
The Libyan Desert (not to be confused with the Libyan Sahara) is a geographical region filling the north-eastern Sahara Desert, from eastern Libya to the Western Desert of Egypt and far northwestern Sudan. On medieval maps, its use predates today's Sahara, and parts of the Libyan Desert include the Sahara's most arid and least populated regions; this is chiefly what sets the Libyan Desert apart from the greater Sahara. The consequent absence of grazing, and near absence of waterholes or wells needed to sustain camel caravans, prevented Trans-Saharan trade between Kharga (the Darb al Arbein) close to the Nile, and Murzuk in the Libyan Fezzan. This obscurity saw the region overlooked by early European explorers, and it was not until the early 20th century and the advent of the motor car before the Libyan Desert started to be fully explored. Nomenclature The term 'Libyan Desert' began to appear widely on European maps in the last decades of the 19th century, typically identifie ...

Kufra District
Kufra or Kofra ( ar, الكفرة '), also spelled ''Cufra'' in Italian, is the largest district of Libya. Its capital is Al Jawf, one of the oases in Kufra basin. There is a very large oil refinery near the capital. In the late 15th century, Leo Africanus reported an oasis in the land of the ''Berdoa'', visited by a caravan coming from Awjila. It is possible that this oasis was identical with either the Al Jawf or the Taiserbo oasis, and on early modern maps, the Al Kufra region was often labelled as ''Berdoa'' based on this report. History The name ''Kufra'' (comes from Kufuh and Epher) itself is a derivation from ''kafir'', the Arabic term for non-Muslims. Kufra did not fall under the dominion of either the Arabs or the Ottomans and was owned by the Arab Bedouin tribe of the Zuwayya only in the mid 19th century, and eventually by the Italians by the 1930s. In 1931, during the campaign of Cyrenaica, General Rodolfo Graziani easily conquered Kufra, considered a strategic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
El Tag
El Tag (; also ''Al-Tag'', ''Al-Taj'') is a village and holy site in the Kufra Oasis, within the Libyan Desert subregion of the Sahara. It is in the Kufra District in the southern Cyrenaica region of southeastern Libya. The Arabic ''el tag'' translates as "crown" in English, and derives from the position above the Kufra basin.Bertarelli (1929), p. 515. El Tag, being on a rise, is without an oasis spring and native date palm habitat. Senussi El-Tag was founded in 1895 by Muhammad El-Mahdi es-Senussi (1844–1902), after the Ottomans forced him and the Senussi Order from Jaghbub in the Cyrenaican desert to Kufra. He was the son of the founder and the supreme leader (1859-1902) of the Order. El-Mahdi founded a Zaouia (''madrassa''—school) with a mosque a low octagonal minaret tower here. He also built several tombs of the Senussi family here, which later included his own therefore making El-Tag a Senussi holy place. Italians and World War II During the colonial Italian Libya p ...

Arkenu Structures
The Arkenu structures, also known as the Arkenu craters, are a pair of prominent circular geological structures in eastern Libya. The structures are approximately and in diameter, and lie about west of Jabal Arkanu on the eastern margin of the al-Kufrah Basin.Paillou P., A. Rosenqvist A., J.M. Malezieux, B. Reynard, T. Farr, and E. Heggy (2003) ''Discovery of a double impact crater in Libya: The astrobleme of Arkenu.'' Comptes Rendus Geoscience. vol. 335, no. 15, pp. 1059–1069.Cigolini, C, C Laiolo, and M Rossetti (2012) ''Endogenous and nonimpact origin of the Arkenu circular structures (al-Kufrah basin-SE Libya)'' Meteoritics & Planetary Science. 47(11):1772–1788. It has been argued that both structures were formed by simultaneous meteorite impacts. Field investigations by Dr. P. Paillou, Dr. A. Rosenqvist, and others reported the presence of impact breccias at the structures’ bottoms, shatter cones pointing toward the center of the structures, and microscopic planar d ...

Gilf Kebir
Gilf Kebir () (var. Gilf al-Kebir, Jilf al Kabir, Gilf Kebir Plateau) is a plateau in the New Valley Governorate of the remote southwest corner of Egypt, and southeast Libya. Its name translates as "the Great Barrier". This sandstone plateau, roughly the size of Puerto Rico, rises from the Libyan Desert floor. It is the true heart of the Gilf Kebir National Park. The name Gilf Kebir was given to the plateau by Prince Kamal el Dine Hussein in 1925, as it had no local name. It is known for its rugged beauty, remoteness, geological interest, and the dramatic cliff paintings-pictographs and rock carvings- petroglyphs which depict an earlier era of abundant animal life and human habitation. Geography and climate The Uweinat mountain range at the very south of the plateau extends from Egypt into Libya and Sudan. Wadis The plateau is crisscrossed by Wadis (dry, seasonal riverbeds). These include: * Wadi Hamra * Wadi Akhdar * Wadi Bakht * Wadi Dayiq * Wadi Firaq * Wadi Gazay ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oasis
In ecology, an oasis (; ) is a fertile area of a desert or semi-desert environment'ksar''with its surrounding feeding source, the palm grove, within a relational and circulatory nomadic system.” The location of oases has been of critical importance for trade and transportation routes in desert areas; caravans must travel via oases so that supplies of water and food can be replenished. Thus, political or military control of an oasis has in many cases meant control of trade on a particular route. For example, the oases of Awjila, Ghadames and Kufra, situated in modern-day Libya, have at various times been vital to both north–south and east–west Trans-Saharan trade, trade in the Sahara Desert. The location of oases also informed the Darb El Arba'īn trade route from Sudan to Egypt, as well as the caravan route from the Niger River to Tangier, Morocco. The Silk Road “traced its course from water hole to water hole, relying on oasis communities such as Turpan in China and Sa ...

Ahmed Hassanein
Ahmed Hassanein Pasha, KCVO, MBE () (31 October 1889 – 19 February 1946) or Aḥmad Moḥammad Makhlūf Ḥasanēn al-Būlākī () was an Egyptian courtier, diplomat, politician, and geographic explorer. Hassanein was the tutor, Chief of the Diwan and Chamberlain to Farouk, the king of Egypt from 1936 to 1952, and also represented Egypt in the 1924 Summer Olympics in fencing. Early life Hassanein was born in 1889, the son of an Al-Azhar University professor, and grandson of the last Admiral of the Egyptian fleet before it was dismantled under British occupation in 1882. He studied at Balliol College of Oxford University. Tutor King Fuad I, father of Farouk, chose Hassanein to tutor the Crown Prince during the Prince's studies as a teenager in London. While Fuad spoke Turkish as his mother-tongue and was therefore unable to eloquently address his own nation, Farouk learned to speak Arabic proficiently under Hassanein's coaching.

Intrusion
In geology, an igneous intrusion (or intrusive body or simply intrusion) is a body of intrusive igneous rock that forms by crystallization of magma slowly cooling below the surface of the Earth. Intrusions have a wide variety of forms and compositions, illustrated by examples like the Palisades Sill of New York and New Jersey; the Henry Mountains of Utah; the Bushveld Igneous Complex of South Africa; Shiprock in New Mexico; the Ardnamurchan intrusion in Scotland; and the Sierra Nevada Batholith of California. Because the solid country rock into which magma intrudes is an excellent insulator, cooling of the magma is extremely slow, and intrusive igneous rock is coarse-grained ( phaneritic). Intrusive igneous rocks are classified separately from extrusive igneous rocks, generally on the basis of their mineral content. The relative amounts of quartz, alkali feldspar, plagioclase, and feldspathoid is particularly important in classifying intrusive igneous rocks. Intrus ...

Granite
Granite () is a coarse-grained ( phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or '' granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is near ...
