“…Their proof for the unconformity is based only on circumstance shreds of evidence, not direct ones, and depended on subjective and biased ideas in the discussion. We discuss, in this section, objectively the claimed unconformity and other results of Ghafur et al (2020). Our field and laboratory evidence refute the presence of an unconformity between Qamchuqa and Kometan Formations (Upper part of Qamchuqa Formation).…”

“…The most concerning issue in Ghafur et al (2020) is their establishment of the 30-million-year unconformity between the Kometan Formation (Turonian-Campanian) and the Qamchuqa Formation (Hauterivian-Cenomanian) in the Zewe Gorge at the southeastern part of Piramagroon anticline (Fig. 20a).…”

“…Recently Ghafur et al (2020) studied nearly the same characteristic of the Qamchuqa Formation on the southwest limb of the Piramagroon-Sara anticline and found an unconformity between Kometan and Qamchuqa formations by which the upper part of the latter formation was removed during the Early Cretaceous. The present study aims to uncover the characteristics, features, and processes of the Qamchuqa Formation, as a unit of the Arabian Northeast Platform during the Early Cretaceous in Sulaymaniyah.…”

Northeastern Arabian Plate Margin is now part of the Zagros Collisional belt and extends nearly parallel to the Iraq-Iran border. The margin comprised, during the Early Cretaceous, of the Arabian Carbonate Platform which is poorly explored. This margin consists of thick carbonate succession and separates the Neo-Tethys Ocean (present Sanandaj-Sirjan Zone) from the Arabian Plate interior. The carbonate succession, as the Qamchuqa and Balambo formations, consists of more than 600 m of dolomite and reefal limestone. The present study focused on records and discussions of evidence of unconformity and paleokarst (UaPK) inside the Arabian platform in northeast Iraq. The study recorded this evidence inside the lower part of the Qamchuqa Formation and the pieces of evidence include limestone conglomerate, plaeo-solution cavities, erosional surfaces, widespread coarse and fine grain detrital limestones, hardground, extensive burrows of Thalassiniodes, and mineralization. The solution cavities shaped a complex network, developed inside fine-grain limestone and filled with yellow to brown ooid and detrital limestones. Most of these features are observable over more than 500 km2 in the Sulaymaniyah and traceable inside gorges and valley sides. Toward the north and northeast of the studied area, the unconformity changes to correlative conformity in the Neo-Tethys basin of the studied area where the sediments consist of laminated and graded detrital limestone (packstone-wackstone) and are deposited as a thick succession of calciturbidite that stratigraphically designated as the Balambo Formation. The result of the present study debates the previously claimed unconformities and uncovers many processes and features of the Northeastern Arabian Carbonate Platform Margin. Additionally, it reveals tectonic and paleogeographic settings of the Arabian Plate Margin that have application in searches for oil and better reconsideration of the geologic setting of the Zagros Belt in the future.
