“…The direction of the emplacement was to the south and southwest ( Fig. 2c; Allemann & Peters, 1972;Glennie et al 1974;Boudier et al 1985;Glennie et al 1990). A break in sedimentation and subaerial exposure marks the onset of closure of the Hawasina and Semail basins in northern Oman after the Early Turonian (Allemann & Peters, 1972;Glennie et al 1974;Béchennec, 1987;van Buchem et al 1996).…”

When the highlands of Arabia were still covered with an ice shield in the latest Carboniferous/Early Permian period, separation of Gondwana started. This led to the creation of the Batain basin (part of the early Indian Ocean), off the northeastern margin of Oman. The rifting reactivated an Infra-Cambrian rift shoulder along the northeastern Oman margin and detritus from this high was shed into the interior Oman basin. Whereas carbonate platform deposits became widespread along the margin of the Neo-Tethys (northern rim of Oman), drifting and oceanization of the Batain basin started only in Late Jurassic/Early Cretaceous time. Extensional tectonics was followed in the Late Cretaceous by contraction caused by the northward drift of Greater India and Afro-Arabia. This resulted in the collision of Afro-Arabia with an intra-oceanic trench and obduction of the Semail ophiolite and the Hawasina nappes south to southwestward onto the northern Oman margin ∼80 m.y. ago. During the middle Cretaceous, the oceanic lithosphere (including the future eastern ophiolites of Oman) drifted northwards as part of the Indian plate. At the Cretaceous–Palaeogene transition (∼65 Ma), oblique convergence between Greater India and Afro-Arabia caused fragments of the early Indian Ocean to be thrust onto the Batain basin. Subsequently, the Lower Permian to uppermost Maastrichtian sediments and volcanic rocks of the Batain basin, along with fragments of Indian Ocean floor (eastern ophiolites), were obducted northwestward onto the northeastern margin of Oman. Palaeogene neo-autochtonous sedimentary rocks subsequently covered the nappe pile. Tertiary extensional tectonics related to Red Sea rifting in the Late Eocene was followed by Miocene shortening, associated with the collision of Arabia and Eurasia and the formation of the Oman Mountains.

“…In the study area, most of the middle and upper Saiq Formation (several hundreds of meters of limestone) were replaced by early diagenetic dolomite (Coy, 1997) ("ED dolomite", according to Vandeginste et al (2015)) ( Vandeginste et al, 2015) (Table 1). During Cretaceous to Neogene times the Neo-Tethys Ocean underwent closure and intra-oceanic subduction initiated in the Cenomanian which continued until the middle Turonian to early Campanian resulting in the obduction of the Semail ophiolite (Boudier et al, 1985;Breton et al, 2004;Hacker, 1994).

“…On the other hand, the geodynamic significance of most ophiolites is well established, as the widespread occurrence of metamorphic soles (Nicolas 1989) and the distinct geochemical signature of immature arc (e.g., Pearce et al 1984) point to an origin in an intraoceanic subduction zone (e.g., Jamieson 1986;Hacker 1994) for most ophiolites. The potential information preserved in ophiolites formed at the initial stages of convergence deserves our attention at different scales (e.g., Boudier et al 1985Boudier et al , 1988Aitchison et al 2000;Beccaluva et al 2004;Berly et al 2006), as they represent the ancient counterparts of modern intraoceanic subduction systems, whereas long-term evolution and deformation mechanisms within subducting and overriding plates are matters of debate (e.g., King 2001;Boutelier et al 2003;Heuret and Lallemand 2005;Doglione et al 2007;Heuret et al 2007;Schellart et al 2007;Schellart 2008).…”
