This study is concerned with a thick succession of polymictic conglomerates which is exposed in the Chwarta, Mawat and Qandil areas inside the Imbricated and Thrust Zone. It is about 1500 m thick and comprises pebbles of boulders of chert, limestone and metamorphic rocks which was previously considered as unit three of the Red Bed Series of the Eoc...

This research talks about the new idea of limestone dolomitization especially in Bekhma and Qamchuqa formations

This study unveils new considerations regarding the dolomitization of the Bekhme and Qamchuqa formations (BQFs), two reefal Cretaceous units in the Iraqi Zagros collisional belt. Previous studies proposed the dolomitization of these formations due to the ascent of Mg-rich hydrothermal solutions through deep faults but lacked substantial supporting...

The present study focuses on finding the relations between the Walash and Naopurdan formations in the thrust zone of the Soran area with the Kolosh and Khurmala Formations in High-Folded Zones of the Shaqlawa area. The study also tries to indicate the relation of these four units with the Iraqi ophiolite, volcanic rocks and Gimo sequence in the Sor...

Iraqi National Journal of Earth Sciences (https://www.iasj.net/iasj?func=issueTOC&isId=9339&uiLanguage=en). A part of the Govanda Formation is studied from northeastern Iraq near the Iraqi-Iranian borders. It consists of polygenic conglomerates, detrital limestones (conglomeratic limestone), and highly fossiliferous limestones of reef-fore-reef fac...

A part of the Govanda Formation is studied in five outcrops from northeastern Iraq near the Iraqi-Iranian borders. It consists of polygenic conglomerates, detrital limestones (conglomeratic limestone), and highly fossiliferous limestones of reef-fore-reef facies with occasional interbedding of terrigenous sediments. Tectonically, the formation is i...

Kometan Formation, in most localities, contains sporadic and rare chert nodules, but in Dokan area, these nodules become widespread and associated with well-developed and high amplitude stylolites. They are mainly distributed along or around the bedding planes. The long axes of nodules and stylolite surfaces are aligned parallel to the bedding plan...

Flysch and molasse facies are recognized in previous studies as syn-and post-orogenic sediments respectively. According to these studies they deposited diachronously and recognized on the basis of difference in lithology. The latter facies consist of mainly sandstone and conglomerate which deposited in nonmarine or shallow marine environment during...

Abstract The Red Bed Series is a Paleocene- Eocene unit, which crops out mainly within the Imbricated Zone and partially within Thrust Zone in Northeastern Iraq. It stretches as narrow northwest-southeast belt near and parallel to the Iranian border. The series mainly consists of alternation of thick beds of clastic rocks of red claystone, sandston...

This paper deals with a rock failure from Pira-Magroon Mountain, Northeastern Iraq. Field study and graphical representation showed that this failure is a rockslide. Being located near Qara-Chattan village, we named this phenomenon as Qara-Chattan Rockslide. About 200 million tons of rock materials are slided from the elevation of 29000 meters abov...

It is mentioned previously that the intermontane basins, in northeastern Iraq, are developed in the Early Paleocene. In present study, the timing, geographic location and geological setting of these intermontane basins are studiedfrom Iraqi Zagros Fold-Thrust Belt during Tertiary. The study achieved in view of literature and recent sedimentological...
