Remarks

The well-known Reshun Conglomerate; it unconformably overlies the Krinj Limestone and is juxtaposed against the Paleozoic Northern sedimentary belt along the Reshun Thrust. Its age is Cretaceous, possibly extending into the Early Tertiary; the Tupop Conglomerate of the lower Chapursan valley is a correlative.
