Paleocurrents beside on obliquely convergent plate boundary (Sulaiman foldbelt, southwestern Himalayas, west-central Pakistan)
Cretaceous to Holocene paleocurrents at the north and south ends of the Sulaiman Range show flow trending westward, then variably eastward, southward, and finally eastward. Pre-orogenic Cretaceous shelf sandstones show dispersal to the southwest, north-northwest, and west-southwest off the craton. However, Paleocene marine sandstones in the south spread east-southeast, and early Eocene deltaic sandstones in the north spread southeast and north. These sandstones indicate slope reversal of the Cretaceous shelf. Post-Oligocene fluvial molasse shows mostly southward drainage. The 3,852 m northern molasse section comprises a lower 2,378 m of claystones and upwardly fining sandstones that are thought to represent meandering rivers, and an upper 1474 m dominated by conglomerates, representing gravelly braided rivers. Lower paleocurrents were more uniform and gradually shifted from southeast to east.
