The southern part of the Mesopotamian foredeep is contiguous with the northern extension of the Gotnia Basin, an area of subsidence and deep-shelfal salt deposition during the Jurassic that extends into adjacent Kuwait. The Gotnia Basin (called the Zubair zone by Jassim and Goff<ref name=Jassimandgoff_2006 />) is characterized by broad, low-angle anticlines that trend and plunge to the north. These anticlines form many oil and gas fields, including the super-giant Rumaila, West Qurna, Zubair, and Majnoon fields ([[:file:M106Ch12Fig03.jpg|Figure 3]]). Values of both Bouguer gravity and total magnetics are low ([[:file:M106Ch12Fig02.jpg|Figure 2]]), indicating a thick sedimentary sequence with a non-magnetic basement.

The Zagros foldbelt and Mesopotamian foredeep end at the Khleisia High (Rutbah subzone of Jassim and Goff<ref name=Jassimandgoff_2006 />), a region of shallow basement and thin sedimentary cover, as interpreted from the high values of the Bouguer gravity map ([[:file:M106Ch12Fig02.jpg|Figure 2]]) and from the deep Khleisia 1 well which drilled to the Ordovician ([[:file:M106Ch12Fig05.jpg|Figure 5]]). Several east-trending extensional grabens that formed in the Late Cretaceous cut across and form the northern and southern boundaries of the Khleisia High ([[:file:M106Ch12Fig03.jpg|Figure 3]]). These include the Anah and Ashtar Grabens to the south ([[:file:M106Ch12Fig05.jpg|Figure 5]]), which appear as relatively low in the total magnetics map ([[:file:M106Ch12Fig02.jpg|Figure 2]]), and the inverted Sinjar Graben to the north, which is a low on Bouguer gravity. There are only a few small fields in northwestern Iraq ([[:file:M106Ch12Fig03.jpg|Figure 3]]).
