Archaeological surveys of the Negev Highlands show that the settlement history of this arid environment oscillated widely over time. This observation is almost entirely based on scant sherd assemblages from surveys, with only a few chronometric ages from one or two archaeological features at a given site. The study included micromorphological analyses to aid identification of sedimentological and post-depositional processes at the studied sites. At Ein Ziq – one of a few large sites in the region – seven samples were dated; they show a very short period of activity in the beginning of the IBA (c. 2450–2200 BCE). OSL age determinations at this site provided evidence for the rapidity of site burial by sediment accumulation.

The luminescence dating instruments are routinely calibrated against the Risø calibrated quartz. The high-resolution gamma spectrometer is routinely calibrated against four reference materials supplied by the IAEA (International Atomic Energy Agency; IAEA-385, IAEA-RGU-1, IAEA-RGTh-1, and IAEA-RGK-1). Fast component The part of the optically stimulated luminescence signal that decays most rapidly during stimulation.

Bioturbation After initial deposition, the reworking of sediment by biota . Sand wedges Cracks formed in frozen ground and then filled with sand; this preserves them in the sedimentary record.

The upper limit of optically stimulated luminescence dating technique is usually defined by signal saturation. In nature the OSL signal saturates even faster than in the laboratory. Here we present a study on natural saturation of OSL and thermally transferred OSL (TT-OSL) signals of quartz grains from Nilotic origin.
