The Sinjar Mountains are a breached anticlinal structure. These mountains consist of an asymmetrical, doubly plunging anticline, which is called the "Sinjar Anticline", with a steep northern limb, gentle southern limb and a northerly vergence. The northern side of the anticline is normally faulted, which results in the repetition of the sequence of sedimentary strata exposed in it. The deeply eroded Sinjar Anticline exposes a number of sedimentary formations ranging from Late Cretaceous to Early Neogene in age. The Late Cretaceous Shiranish Formation outcrops within the middle of the Sinjar Mountains. The flanks of this mountain range consist of outward dipping strata of the Sinjar and Aliji formations (Paleocene to Early Eocene); Jaddala Formation (Middle to Late Eocene); Serikagne Formation (Early Miocene); and Jeribe Formation (Early Miocene). The Sinjar Mountains are surrounded by exposures of Middle and Late Miocene sedimentary strata
