Late Quaternary human settlement patterning in the Jebel Gharbi.

This paper presents the latest results of geoarchaeological research on the Upper Pleistocene sequence in the Jebel Gharbi (previously called Jebel Nafusah), a mountain range located in Tripolitania, northwestern Libya. Numerous archaeological sites are found adjacent to springs that formed as a consequence of tectonic activities. The springs originated when Upper Pleistocene earthquakes produced ground displacements that created water outlets, some of which are still active. Springs are spread all along the massif and at the foot of the mountains in Jebel Gharbi. We suggest that they offered attractive resources to populations coming from drier parts of North Africa or the near-by Sahara. The earliest sites associated with the springs include Aterian lithic techno-complexes that have been dated between 80,000 and 40,000 BP. Since then, these springs have attracted many populations, as documented here by settlements belonging to the Later Stone Age (Upper Palaeolithic), Iberomaurusian (Late Upper Palaeolithic or Epipalaeolithic), Neolithic, Roman period, and present time.
