My name is Biruk Abera Cherkose, I am a Ph.D. student and RA in the Department of Geosciences at the United Arab Emirates University (UAEU). I am studying the UAE-Oman Ophiolite and deep crustal structure in the northern Emirates using the Magnetotelluric (MT) Method.

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, 50-150 km wide, and about 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 electrical structures beneath the UAE mountains.
This study aims at understanding the nature of the deep crustal electrical structure of the northern Emirates. This involves determining the geometry and the electrical properties of the deep structure of the Semail ophiolite and investigating the thickness and electrical properties of the deep sedimentary basin (Foreland basin) west of the Hajar mountain belt. The study also targets imaging the underlying thrust sheets (Hawasina and Haybi complexes) underneath the Semail ophiolite as well as to characterize the basement rocks beneath the sedimentary basin in the west and the Allochthonous units in the East.
