The geological history of the [[Arabian Basin]], which is a part of the [[Arabian Plate]] ([[:file:M114CH01FG01.jpg|Figure 1]]), has been discussed in detail (e.g., Powers et al., 1966<ref name=Powersetal1966>; McGillivray and Al-Husseini, 1992; Alsharhan and Nairn, 1997; Wender et al., 1998; Al-Hajri and Owens, 2000; Al-Husseini, 2000; Konert et al., 2001; Sharland et al., 2001; Ziegler, 2001; Faqira et al., 2009; Cantrell et al., 2014 and references cited therein).
