The Triassic succession of the Nakhlak area in Central Iran consists of: (1) the Alam Formation, a sequence of shallowing- and coarsening-upward marine turbidites deposited on the forearc side of an accretionary prism; (2) the Bāqoroq Formation, a sequence of coarse- to fine-grained, polymictic, fluvial conglomerates; and (3) the Ashin Formation, which comprises alternating distal marine shales and sandstones that have turbiditic characteristics. We studied the petrography and stratigraphy of a 1500-m-thick section from the siliciclastic Bāqoroq Formation, located at lat 33°33′41″N, long 53°47′49″E. This formation is located between the Alam Formation (below) and the Ashin Formation (above). Forty samples were petrographically analysed, of which 11 were used for point-counting analysis. Point-counting results plotted on a Folk diagram show that litharenite and feldspathic litharenite are common.
