One line on the map: A review of the geological history of the Semail Thrust, Oman-UAE mountains

The Semail Thrust in the Oman-UAE mountains is mapped along base of Ophiolite, a 10–15 km thick sequence Cenomanian oceanic crust and upper mantle emplaced from NE to SW onto previously passive, Mid-Permian continental margin Oman. juxtaposition ophiolite with range different rock types sourced depths suggest complex tectonic history for this major fault shear zone. Here we summarize previous work present an overview fault. as single line on geological map, yet it covers variety structural features spanning 40–45 surface, time scale ∼96 Ma (or earlier) Eocene time. evolution includes (a) roof or ductile zone exhumed subduction (granulites, amphibolites greenschists metamorphic sole), (b) deep (Banded Ultramafic Unit), (c) brittle above foreland-directed fold-thrust belt, (d) out-of-sequence exhuming higher thrust sheet deeper level lower granulites (e.g. Bani Hamid, UAE), (e) late truncating underlying units Hawasina Window), (f) passive beneath HP rocks ‘Semail Thrust’ below Muscat peridotite, Ruwi mélange high-pressure northern Saih Hatat), (g) reactivated normal bounding rising footwall culminations, notably Jebel Akhdar, Nakhl, Hatat anticlines. Different stages can be out interpreted regions Oman Mountains.
