Abdel -Rahman Fowler graduated with B.Sc. (Honors, 1st class) in geology from Sydney University, Australia, in 1977. After experience in the uranium and tin exploration and mining industry in NSW, Queensland and Northern Territory, he obtained a Ph.D. in structure and tectonics at the University of New South Wales (UNSW) in 1986. He has instructed in structural geology and other geoscience disciplines at UNSW and La Trobe University, Victoria, and has served at the United Arab Emirates University since 1999. His main interests lie in structural geology and tectonics, but extend to stratigraphy/ sediment ology and geochemistry. He has con ducted research work in Australia, Egypt, Turkey and UAE, and has published more than 50 papers in international journals and has contributed to books dealing with the geology of the Arabian–Nubian Shield. He has received awards for research excellence at UAEU.  Nuri Fello a Senior Geologist with National Oil Corporation in Tripoli, and he was working with Several Oil Companies in Libya and IOC’s (Zueitina Oil Company, Repsol Oil Operations (Akakus), Petro-Canada (Suncor) and Petrobras Oil Company). In addition, Nuri has been working on the entire exposure for the Lowermost Silurian succession “Hot Shales” of the Ghat area in the Murzuq Basin, SW Libya. His work on both subject’s matter has led to issue more than 30 publications plus produce Two DVD's about the source rock in Murzuq Basin, and geological petroleum system in Libya. In 2018 Dr. Fello, Chairman of Scientific Committee for the Benghazi International Conference of Oil and Gas (BIEOG2018). This event is an internationally distinguished event hosted in Benghazi City – Libya, October 24th – 26th 2018. (www.bieogexpo.ly). In 2009 Fello organized with Petro-Canada the first Geological Field Trip to Jabal Nafusah, NW Libya; and in 2008 Fello Organizing Committee Chairman in the First International Conference "Geo-Information Technologies to Support Sustainable Development in Africa – GITSDA"08" which held in Tripoli at The Academy of Graduate Studies April 05th -07th 2008. Recently; December; 2020, Dr. Fello have been nominated as Libyan Represent (Focal Point) Head of the UNESCO Global Geoparks in Libya. He is Member of the International Association Sedimentology (IAS); Member of American Association of Petroleum Geology (AAPG); Member of the European Association of Geoscientists and Engineers (EAGE). Member of the Earth Sciences Society of Libya (ESSL). Member of the Global Environmental Facility (GEF) and Member of the Climate Changes Group in Libya. Amara Masrouhi is a professor of structural geology at Geo-resources Laboratory, Water Research and TechnologiesCenter of Borj Cedria (Tunisia) since February 2015. Currently under international cooperation contract between Tunisia and KSA and have a position of a Professor of Structural Geology in Faculty of Earth Sciences, King Abdulaziz University (KSA). Visiting professor at CEREGE in Aix-Marseille University (France) from 2011 to 2016. mains interests are tectonic processes in the Maghreb belts and the Arabian Nubian Shield. Early work focused on salt tectonics and developing models for the construction of the salt structures in Tunisia. Since 2013 a second research focus: tectonics modeling and deformation restoration. Rémi Leprêtre specialized in the behavior and deformation of crustal domains, either in active settings or within intraplate domains (craton, intraplate belts). He works with thermochronology tools (AFT, AHe), geochemistry (organic matter) and the structural geology tools to decipher the evolution of his studied areas. He particularly studied theNorthern Maghreb, in the Atlas belt, the alpine Tell-Rif systems and the vertical evolution of the West African Craton.
