Welcome, my name is Biruk Abera Cherkose, I am a Ph.D. student at the United Arab Emirates University (UAEU). I am studying the UAE-Oman Ophiolite using the Magnetotelluric (MT) Method.
My Ph.D. Research Title: A deep Magnetotelluric study of the UAE mountain belt: Implications for collision tectonics and ophiolite emplacement
Fig. The UAE-Oman (Samail) Ophiolite. An ophiolite is a part of the oceanic crust and the upper mantle that has been uplifted and exposed above sea level and often emplaced onto continental crustal rocks. They are sequences of oceanic crust and upper mantle materials formed at different geological times found near the surfaces of continents (Pilia et al., 2015).
Supervisor: Associate Professor Dr. Hakim Saibi
The Oman-UAE mountain belt represents one of the largest and best-preserved ophiolites complexes in the world. The mountain belt is a 700 km long, 50 km wide, and 15 km thick thrust complex that formed in the Late Cretaceous by emplacement onto the Arabian continental margin. In this project, a geophysical electromagnetic technique, the Magnetotelluric (MT) method will be used to map deep crustal conductive structures beneath the UAE mountains along two profiles. The MT data to be collected in this project will be jointly inverted with existing seismic data, courtesy of the UAE Ministry of Energy. The inverted data will provide a model for deep (10’s km) crustal structures in the northeastern UAE. The near surface structure of the UAE-Oman mountains is reasonably well known from previous detailed geological studies. However, the deeper structures in the lower crust and upper mantle are less well known. The main goal of this proposal is to generate multidimensional (1D, 2D and 3D) electrical distribution models using joint inversion of MT and seismic data to constrain models for the obduction of the Semail Ophiolite.
