The claimed igneous rocks that located inside clastic sedimentary rocks are:
1-Chalki volcanics, located with and inside Perispiki Red Bed in the Khabour valley , Dohuk area( see Bellen et al,1959)
2- Gercus Basalt , located inside Gercus Red Bed at about 10 km northwest of Dohuk area (see Karim et al.2020) and Kettanah (2019).
3- Hamrin Basalt, located inside Injana (Upper Fars)Formation (sandstone and claystone) (see Kettanah et al. (2021), located inside Red Bed Series.
4- Mawat Ophiolite (see Buday and Jassim, 1987), located inside Red Bed Series.
5-Bultat (Qaladiza) Ophiolite (see Buday and Jassim, 1987), located inside Red Bed Series.
6-Penjween Ophiolite (see Buday and Jassim, 1987), located inside Red Bed Series.
7-Peshashan (Qandil mountain)Ophiolite (see Buday and Jassim, 1987), located inside Red Bed Series.
8-Hassan Bag ophiolite (see Ali ea al. 2012), located inside Red Bed Series.
9- Avroman basaltic body (Biara Basaltic body) (see Sasvari et al. (2015) and Karim and Abioui, 2020), located above Conglomerate of Tanjero Formation ( Kato Conglomerate).
According to my field and office works, they occur in side clastic sedimentary rocks because what called igneous rocks, they are all sedimentary rocks (some of them metamorphosed and called Ophiolite)
Perhaps because they were all erupted at the same time (in the same orogenic event) after the sedimentary rocks were laid down.
Sir Karim, I understand your question. But to be sure on what I am going to comment, can you please kindly ask your question again below, rephrasing your question one more time.
Please also comment on what you have in mind or suggestions in support of your question. Thank you.
If the igneous rocks are truly basalts and "ophiolites", then the classic explanation of their association with red bed clastics and conglomerates is that they represent magic to ultramafic magmatism in a continental extensional setting, i.e. rift or back arc. An olistostromic or suprasubduction zone setting seems unlikely given the continental to shallow marine setting indicated by sediments. But you say that these "igneous" rocks are just highly altered sediments -part of the sedimentary package. That is intriguing, but can you give more details on their petrography and mineralogy? These should be fairly diagnostic.
