Here, OSL dating was applied to “wheels” in the Wadi Wisad area, in the eastern badia of Jordan.
OSL dating generated ages that fall into the Late Neolithic to Chalcolithic and Early Bronze Age periods.
Optically Stimulated Luminescence (OSL) dating has emerged within the last 20 years as a key Quaternary absolute dating tool, with a wide range of terrestrial and marine applications.
Optical dating techniques employ ubiquitous quartz or feldspar grains to directly date the deposition of sedimentary units.
The basic cost is £550/sample plus reporting time based on your requirements.
The report will contain OSL results calibrated for sample water content and salinity.
We analyse the quartz or feldspar minerals in sand deposits.
When these quartz or feldspar minerals are exposed to the ionising radiation emitted by the radioactive isotopes in zircons, electrons within the crystals migrate and become trapped in their crystal structure.
If we assume that the radiation dose rate of the sediment has remained constant over time, then if we measure that dose rate, we can calculate the sample age. This chronological spectrum is consistent with the well-documented prehistoric activities at the archaeological site of Wisad Pools, also located in the Wadi Wisad area.Spatial analyses of the “Works” in Wadi Wisad and in the Azraq Oasis revealed that: 1) the wheels are organized in clusters, 2) the spatial distribution of the wheels is predetermined by the kites, 3) the kites were most probably created earlier than the wheels in the study areas and 4) a cluster of wheels nearby the Azraq Oasis tentatively demonstrates ranking and, perhaps, tendency for alignment, although this is not the case for the other wheel-clusters studied.One room serves as preparation laboratory, where all incoming samples are unpacked and chemically treated to purify the sample and extract the desired minerals in the right grain size. The other room houses most of the modern electronic equipment, including: Please contact Ningsheng Wang (MSc.) for more information.
