The Mawat ophiolite complex is of Cretaceous period as a residue oceanic crust covers about 200 km2, Northeastern Iraq.. serpentinite rocks are exposed diapir in the northeastern suture Zagros zone Iraq near Beetwat village, field study and petrography reveal two types serpentinite, shear massive, with three serpentine varieties. affected by secondary processes such diagenesis, metamorphism hyd...

The Solund–Hyllestad–Lavik area affords an excellent opportunity to understand the ultrahigh-pressure Scandian orogeny because it contains a near-complete record of ophiolite emplacement, high-pressure metamorphism and large-scale extension. In this area, the Upper Allochthon was intruded by the c. 434 Ma Sogneskollen granodiorite and thrust eastward over the Middle ⁄ Lower Allochthon, probably...

The northern Oman margin is a key area for understanding the emplacement of Semail Ophiolite and obduction processes in general. This study uses grid 2D-multichannel seismic lines tied to well data characterize offshore domain reappraises post-obduction history margin. West Muscat, Sohar basin, late Cretaceous Paleogene tectonic mega-sequence records syn- late-obduction stages deposition erosio...

The mineral ore potential of many mountainous regions of the world, like the Kurdistan region of Iraq, remains unexplored. For logistical and sometimes political reasons, these areas are difficult to map using traditional methods. We highlight the improvement in remote sensing geological mapping that arises from the integration of geomorphic features in classifications. The Mawat Ophiolite Comp...

Furnes et al. (1) reported that a sheeted-dike complex they identified within the ~3.8billion-year-old Isua supracrustal belt (ISB) in Greenland provides the oldest evidence of oceanic crustal accretion by spreading. However, they did not alert readers that the ISB contains supracrustal rocks and mafic dikes of different ages (2, 3). They also failed to demonstrate that the proposed components ...

The Kahnuj ophiolitic complex, a part of the Jazmurian ophiolitic belt, is located on the western boundary of the Jazmurian depression and is bounded by two major fault systems. There is a well-preserved, ophiolite pseudostratigraphy of early Cretaceous to early Palaeocene age and has a bearing on the Mesozoic development of southeastern part of Iran and adjacent region. The Kahnuj ophiolitic c...
