The major volcanoes in the region are located in the following States: Algeria, Cameroon, Cape Verde Islands, Chad, Comoros Island, Democratic Republic of Congo, Djibouti, Eritrea, Ethiopia, France (Reunion Island), Kenya, Madagascar, Mali, Niger, Nigeria, Rwanda, Sao Tome and Principe, Spain (Canary Islands, Madeira), Sudan, Tanzania and Uganda. The names of the concerned volcano are listed in APPENDIX K (source: Smithsonian Institution). This document is the AFI Air Traffic Management (ATM) Volcanic Ash Contingency Plan which sets out standardised guidelines and procedures for the provision of information to airlines and en-route aircraft before and during a volcanic eruption. Volcanic contamination, of which volcanic ash is the most serious, is a hazard for safe flight operations. Mitigating the hazards posed by volcanic ash in the atmosphere and/or at the aerodrome cannot be resolved in isolation but through collaborative decision-making (CDM) involving all stakeholders concerned. During an eruption volcanic contamination can reach and exceed the cruising altitudes of turbine-powered

The belt includes three felsic shield volcanoes, the Rainbow, Ilgachuz and Itcha ranges as its most notable features, as well as regionally extensive cone fields, lava flows, dyke swarms and a pluton. Volcanic activity took place periodically from the Late Miocene to the Holocene.

LaMoreaux 2008 iii RECOGNIZING ICE-CONTACT TRACHYTE-PHONOLITE LAVAS AT THE MOUNT EDZIZA VOLCANIC COMPLEX, BRITISH COLUMBIA, CANADA Kristen A. LaMoreaux, M.S. University of Pittsburgh, 2008 Mount Edziza Volcanic Complex (MEVC) lies within the Northern Cordilleran Volcanic Province (NCVP), in northwest British Columbia, Canada. The eruption products have been emplaced in a variety of subaerial, sub-ice and subaqueous environments from about 8Ma to less than 2000 y.b.p. (Souther, 1992). Ice Peak Formation (IPF) trachyte lava flows of approximately 1Ma age (Souther, 1992) are exposed at Ornostay Bluff (OB) and Koosick Bluff (KB). These flows comprise basal flow breccias overlain by massive conchoidally-fractured lava with large, poorly-developed columns, and local flow banding. Edziza Formation (EF) approximately 1Ma (Souther, 1992) phonolite is exposed at Triangle Dome (TD). TD can broadly be divided into an upper and lower zone. The upper zone comprises poorly-developed columns in addition to prominent jointing. In the lower zone the columns are planar and 75cm- 3m-wide in the interior of the complex grading into fan-like and curved subhorizontal columns <75cm-wide in the outer margins of the lower zone.

  • Emi Koussi Chad
    Emi Koussi Chad Perpetuated by the breathtaking and somewhat bizarre landscape of the Tibesti Mountains, Emi Koussi is home to extinct volcanic peaks and arguably the most isolated human settlements on earth. Embark on the Saharan journey where new encounters, landscapes, and cultures await. Take a camel ride through the abyss of Koboué, delve into prehistoric times to see ancient rock paintings, and sail on the vast dunes of Erg du Djourab. Chad has opened its doors once again to this untouched region, giving you access to its geological paradise of canyons, gueltas, sea arches, and oases. History Emi Koussi is made of rocks from the the geological epoch of Holocene (some 11,500 years ago) when the glaciers began to retreat. It is a part of 'Tibesti' mountain range, which means "place where the mountain people live," This region has been the territory of the Tubu people. Things to Do in Emi Koussi Given the far-flung location, unpredictable environment, and harsh weather conditions, this region doesn't seem tempting enough in the beginning, still, there are plenty of activities to enjoy around the mountain. Outdoor Thrills – Witness the camel racing put on by the Tubu tribes or go for a challenging mountain biking. The varied landscape of Tibesti massif and the Sahara provides ample opportunities for hiking and trekking. While, the trail to hike Emi Koussi is 108 miles long, the legendary 88-mile long Ennedi Eternel trail, with moderate difficulty, is the most famous in the country. The entire ascent to Emi Koussi, around the Era Kohor, and finally on to Yi Yerra hot springs, normally takes three days.

The basanites have a microphyric texture with olivine phenocrysts in a fine- grained doleritic groundmass. The olivine contains inclusions of Al–Cr spinel. The microlites consist of cli- nopyroxene, plagioclase, magnetite, and apatite, and the interstitial phases are leucite, nepheline, and analcime. The Mount Khukhch basanites are characterized by elevated concentrations of MgO, TiO2, Na2O, and K2O, high concentrations of Co, Ni, Cr, Nb, Ta, Th, U, LREE (LaN/YbN = 10.8–12.6, DyN/YbN = 1.4–1.6) at moder- ate concentrations of Zr, Hf, Rb, Ba, Sr, Pb, and Cu.

  • Aorounga and Gweni Fada Impact Structures, Chad, Central Africa: Petrology and Geochemistry of Target 1 2 3 2 Rocks

Summary: Rocks - mainly sandstones - from two impact structures in Chad, Aorounga and Gweni Fada, were studied for their petrographical, geochemical, and isotopic characteristics. The rocks have chemical and isotopic compositions that are typical of the upper continental crust. No clear signature for the presence of a meteoritic component was found in any of the samples. In rocks from both craters, abundant evidence for shock metamorphism was found in the form of multiple sets of planar deformation features in quartz, confirming the impact origin for both structures. Their crystallographic orientations indicate a fairly high shock level and are characteristic for the orientations observed in sandstones, with the higher frequencies being fairly abundant. Introduction and Geology: In 1994, only 15 confirmed impact structures were known in Africa [1]; since that time, three new African impact structures have been identified: the small 220 m diameter Sinamwenda crater in Zimbabwe, the 14 km diameter Gweni-Fada complex crater in Chad (see below), and the large (200 km diameter) Morokweng impact structure in South Africa (e.g., [2]).
