Geology of recently recognized lithologies inside the Red Bed Series in the Chwarta-Mawat area, Kurdistan Region, NE-Iraq

The sequence of the coastal siliciclastic facies Paleocene-Eocene Zagros Foreland Basin is well exposed in Chwarta-Mawat area, north Sulaimani Governorate, northeastern Iraq. According to previous studies, this designated as Red Beds Series (RBS), consisting more than 2000 m fine and coarse red grey clastics. present study found recently recognized lithologies (RRLs) about 100 thick inside series encompassed green marlstone with subsidiary detrital limestone which has significant tectonic paleogeographic results. petrography, biostratigraphy, boundary conditions studies are applied uncover their origin. new deposited subsiding basin Imbricate Zone during Middle Eocene. During age, Tertiary was separated by a paleohigh into two basins, (northern southern basins). In northern basin, RRLs have deep Naopurdan Formation while Pila Spi lagoonal facies. former formation reefal shelf area northeast Chawrta Mawat Towns. RRLs, units one (in Thrust Zone) correlated respectively Spi, Sinjar Gercus formations High Folded Zone. These correlations shown on stratigraphic columns models aid nannofossil benthonic foraminiferal studies. This most important step for solving setting Iraq better understanding Collisional belt.
