Abstract
The attention of the present authors is drawn to what looks like odd or even erroneous evidence presented by a paper recently published by Karim and Al-Bidry (2020), focusing on the Zagros Metamorphic Core Complex and providing an example from Bulfat Mountain, Qala Diza area, Kurdistan Region, northeast Iraq. For instance, the ophiolite at Mawat is of the Cretaceous age (105 ±5 Ma; Mohammad and Qaradaghi (2016), the plagiogranites are also of the Cretaceous age, but are slightly younger (92.6 ±1.2 Ma - Mohammad and Qaradaghi (2016), 96.0 ±2.0 Ma - Ismael et al. (2017) and the Hasanbag ophiolite is 106-92 Ma (Ali et al., 2012). On the other hand, 40Ar- Ar dates on the magmatic feldspar separates from the Walash and Naopurdan volcanic rocks indicate an Eocene-Oligocene age (43.01 ± 0.15 to 24.31 ± 0.60 Ma; Ali, 2012; Ali et al., 2013). Many studies of the Zagros region have been undertaken on structure, origin of the ophiolites and the related igneous rocks, as well as o
