Chaîne Du Thaljah
The Chaîne du Thaljah is a range of mountains in the Gafsa Governorate of Tunisia. Huge deposits of phosphates were found at the base of the chain on 1885. Exploration The line of mountains runs in a roughly east–west direction from Gafsa in Tunisia to Negrine in Algeria, crossing the border not far from the small oasis of Tamerza. The highest point is the Jebel-Bliji. On the north side, at a place called Es Safia south-southeast of Tamerza, a rock painting was found on an overhanging rock wall at the entrance of a deep ravine. It depicts animals and men in silhouette, in blood on a yellow-ochre background, all slightly glazed. It was probably made by Berbers between the Stone and Bronze Ages. In 1885–86 the geologist Philippe Thomas explored the southern area of Tunisia between the meridian of Kairouan and the Saharan chotts, covering a vast area. He also explored the western area, which his colleagues had neglected, particularly the Chaîne du Thaljah or Chaîne du Tseldja ...

Philippe Thomas
Philippe Thomas (4 May 1843 – 12 February 1910) was a French veterinarian and amateur geologist who discovered large deposits of phosphates in Tunisia. Despite the huge economic importance of his discovery, he received little recognition during his life. Monuments to Thomas in Tunisia were destroyed after the country gained independence. Career Early years (1843–85) Philippe Thomas was born in Duerne, Rhône on 4 May 1843. He attended the École nationale vétérinaire d'Alfort, where he was a brilliant student, and the Cavalry School. He was named an Army Veterinarian in 1865. He was assigned to Algeria but returned to France at the start of the Franco-Prussian War (1870) and fought in various engagements. He returned to Algeria after the war and took part in suppression of the revolt in the Kabylie in 1871. In his spare time, he studied geology, paleontology, and other scientific disciplines. Thomas became a qualified geologist. Thomas classified the succession of Eoc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kairouan
Kairouan (, ), also spelled El Qayrawān or Kairwan ( ar, ٱلْقَيْرَوَان, al-Qayrawān , aeb, script=Latn, Qeirwān ), is the capital of the Kairouan Governorate in Tunisia and a UNESCO World Heritage Site.

Chott
In geology, a chott, shott, or shatt (; ar, شط, šaṭṭ, lit=bank, coast) is a salt lake in Africa's Maghreb that stays dry for much of the year but receives some water in the winter. The elevation of a chott surface is controlled by the position of the water table and capillary fringe, with sediment deflation occurring when the water table falls and sediment accumulation occurring when the water table rises.Swezey, C.S., 2003, The role of climate in the creation and destruction of continental stratigraphic records: An example from the northern margin of the Sahara Desert, in Cecil, C.B., and Edgar, N.T., eds., Climate Controls on Stratigraphy: SEPM (Society for Sedimentary Geology) Special Publication 77, p. 207-225. They are formed—within variable shores—by the spring thaw from the Atlas mountain range, along with occasional rainwater or groundwater sources in the Sahara, such as the Bas Saharan Basin. Water sources The chotts of the Sahara are fed intermittently d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth b ...

Eocene
The Eocene ( ) Epoch is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope Carbon-13, 13C in the atmosphere was exceptionally low in comparison with the more common isotope Carbon-12, 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Popigai impact structure, Siberia and in what is now ...

Marl
Marl is an earthy material rich in carbonate minerals, clays, and silt. When hardened into rock, this becomes marlstone. It is formed in marine or freshwater environments, often through the activities of algae. Marl makes up the lower part of the cliffs of Dover, and the Channel Tunnel follows these marl layers between France and the United Kingdom. Marl is also a common sediment in post-glacial lakes, such as the marl ponds of the northeastern United States. Marl has been used as a soil conditioner and neutralizing agent for acid soil and in the manufacture of cement. Description Marl or marlstone is a carbonate-rich mud or mudstone which contains variable amounts of clays and silt. The term was originally loosely applied to a variety of materials, most of which occur as loose, earthy deposits consisting chiefly of an intimate mixture of clay and calcium carbonate, formed under freshwater conditions. These typically contain 35–65% clay and 65–35% carbonate. The te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
