“…The rifting and opening of the South Caspian-Black Sea Basin, which opened in the Middle Jurassic, continued in the Late Jurassic (Berberian 1983;Bazhenov et al 1996;Brunet et al 2003;Nikishin et al 2003;Hinds et al 2004;Kazmin and Tikhonova 2006). The Neotethys 2 basin became wider; the Neotethys 1 basin subduction continued, making it narrower (Glennie 1992;Alavi 1994;Sengör and Natal'in 1996;Golonka 2004;Shahabpour 2005;Sheikholeslami et al 2008;Arfania and Shahriari 2009;Glennie et al 2011;Kargaranbafghi et al 2012).…”

“…The Armenian Basin, as a Neotethyan back-arc basin, was an active Andean-type margin during the Middle Jurassic-Lower Cretaceous Kazmin and Tikhonova 2006;Galoyan et al 2009;Rolland et al 2009;Sosson et al 2010;Rolland et al 2011). A tensional basin was formed between the Sanandaj-Sirjan and the Central Iran zones, which later created Neotethys II (Glennie 1992;Alavi 1994;Sengör and Natal'in 1996;Golonka 2004;Shahabpour 2005;Sheikholeslami et al 2008;Arfania and Shahriari 2009;Glennie et al 2011;Kargaranbafghi et al 2012).

“…Owing to the pressure from the Arabian Block and continuation of Neotethys spreading, the Allahyarlu-Kaleybar-Northern Iran Basin began northward subduction. Therefore the northern margin of this basin changed to an active continental margin (Alavi 1991a; Natalin and Sengör 2005;Sheikholeslami and Kouhpeyma 2012), while the main Neotethys Basin was spreading (Glennie 1992;Alavi 1994;Golonka 2004;Shahabpour 2005;Sheikholeslami et al 2008;Arfania and Shahriari 2009;Kargaranbafghi et al 2012).…”

Multiphase Structural Evolution of a Continental Margin During Obduction Orogeny: Insights From the Jebel Akhdar Dome, Oman Mountains

et al. 2018

The structural evolution of the carbonate platform in the footwall of the Semail ophiolite emplaced onto the passive continental margin of Arabia helps to better understand the early stages of obduction‐related orogens. These early stages are rarely observable in other orogens as they are mostly overprinted by later mountain building phases. We present an extensive structural analysis of the Jebel Akhdar anticline, the largest tectonic window of the Oman Mountains, and integrate it on different scales. Outcrop observations can be linked to plate motion data, providing an absolute timeframe for structural generations consistent with radiometric dating of veins. Top‐to‐S overthrusting of the Semail ophiolite and Hawasina nappes onto the carbonate platform during high plate convergence rates between Arabia and Eurasia caused rapid burial and overpressure, generation and migration of hydrocarbons, and bedding‐confined veins, but no major deformation in the carbonate platform. At reduced convergence rates, subsequent tectonic thinning of the ophiolite took place above a top‐to‐NNE, crustal‐scale ductile shear zone, deforming existing veins and forming a cleavage in clay‐rich layers in early Campanian times. Ongoing extension occurred along normal‐ to oblique‐slip faults, forming horst‐graben structures and a precursor of the Jebel Akhdar dome (Campanian to Maastrichtian). This was followed by NE‐SW oriented ductile shortening and the formation of the Jebel Akhdar dome, deforming the earlier structures. Thereafter, exhumation was associated with low‐angle normal faults on the northern flank of the anticline. We correlate the top‐to‐NNE crustal‐scale shear zone with a similar structure in the Saih Hatat window to develop a unified model of the tectonic evolution of the Oman Mountains.

Various classes of microbial and biomolecular evidence from global studies in marine and continental settings are used to identify a set of reactions that appear to support microbial metabolism during serpentinization of ultramafic rocks. Geochemical data from serpentinizing ecosystems in the Samail ophiolite of Oman are used to evaluate the extent of disequilibria that can support this set of microbial metabolisms and to provide a ranking of potential metabolic energy sources in hyperalkaline fluids that are direct products of serpentinization. Results are used to construct hypotheses for how microbial metabolism may be supported in the subsurface for two cases: ecosystems hosted in rocks that have already undergone significant serpentinization and those hosted by deeper, active serpentinization processes.
