Relative dating of deposits of the Mishan Formation based on foraminifera and Strontium isotope in northwest and west of Bandar Abbas, south Iran
For studying of biostratigraphy of Mishan Formation in Bandar Abbas hinterland, a stratigraphic transection including Handun, Anguru, Baviyun, and Nakh sections was selected in northwest and west of Bandar Abbas. A total 668 samples investigated from Mishan Formation which 515 hard and 153 soft samp...
