The Quaternary Zarloukh Bentonite –Tuff (ZBT) deposit occurs within the Hemrin South Mountain, northern Iraq. The ZBT deposit occurs as depression-filling exposed on the erosional surface of the siliciclastic Pliocene Muqdadiya Formation and covered by an overburden of recent sediments. The thickness of the studied industrial bentonite bed is ~80−100 cm, occurring at the bottom of these depressions, covered by ~3−4 m thick bedded volcanic tuff, which also contains many 10–12 cm thick bentonite layers along its bedding planes.
