The evolution of settlement patterns in the eastern Oman from the Neolithic to the Early Bronze Age (6000-2000 BC)

The region of eastern Oman (called Ja'alan) is often compared to the Arabian deserts, which are typically and and depopulated areas. Today, this geographical definition is correct: the geographic and climatic conditions (low precipitation, pronounced dryness, high evaporation) indicate an arid region, and the area is sparsely populated. Between the Neolithic and the Early Bronze Age, the geographic and climatic conditions did not change much, and were slightly more humid than at present. Although the term "green Ja'alan" does not describe this area, we observe that the region was occupied by a quite substantial population. Since 1985, surveys and excavations have been carried out and more than 4000 archeological structures are now listed. The spatial distribution of these sites differs for each period, from Neolithic seasonal camps to oasian settlements of the Early Bronze Age. To cite this article: J. Giraud, C. R.
