The Oman Mountains expose Permo-Mesozoic shelf rocks of Arabia overridden by continental slope/basinal sediments and Semail Ophiolites during Late Cretaceous. A major syntaxis is represented by the Musandam Peninsula and Dibba Zone. The overthrusting of allochthonous units onto the Musandam shelf carbonates initiated during the Cenomanian. Structural analyses in the Musandam Peninsula constrained top-to-the-west thrusting that took place 74–60 Ma ago (U-Pb datings of synkinematic calcites), about 15–30 Ma after the obduction of the Semail Ophiolite.

The Dibb? burial complex, represented by two ‘long collective graves’ (LCG1 and LCG2), a later Parthian grave, and several pits with ritual offerings, is located on the eastern coast of the Musandam peninsula, Sultanate of Oman. The paper mainly deals with LCG2. When all the external features are taken into account, LCG2 is a 23 m-long and 4.5 m-wide structure, which was built using different techniques and employing both local stones and mud brick. The whole area seems to have been continuously occupied from the Late Bronze Age (1600–1350 BC) until the Iron Age II/III period (c.600 BC).
