The Jal Az-Zor Formation sediments in north Kuwait were deposited on the southwestern margin of the Zagros foreland basin. They are organized into 30–60 ft (9–18 m)–thick repeated fining upward high-frequency sequences. The sequences generally consist of conglomerate and pebbly sandstone, coarse- to fine-grained sandstone, muddy sandstone, siltstone, and mudstone lithofacies, ideally stacked in ascending order. In upper part of the sequences, burrowing and fossiliferous horizons are developed, which reflect marine influence during their deposition. Each sequence is interpreted to have been developed by infilling of an incised valley during base-level rise. Such valleys had been cut down into...
