Use of luminescence dating in archaeology
With improvements in methodology and instrumentation, luminescence dating is becoming a much more useful chronometric tool in archaeology. Procedures for dating ceramics are relatively routine and their accuracy has been demonstrated in a number of studies. Research is aimed at applying ceramic dating in situations where other methods lack the direct dating ability of luminescence to resolve ch...
متن کاملDating the First Australians
The dating of selected archaeological and megafaunal sites from the Australian region is reviewed, with emphasis on recent work at some of the oldest sites. Improved chemical procedures with decreased analytical background for 14C analysis, combined with new luminescence dating methods, has confirmed many of the results processed decades ago and significantly increased the maximum age for some ...
متن کاملEffect of dust event timing on glacier runoff : sensitivity analysis for a Tibetan glacier
The impact of the timing of dust deposition on glacier runoff was evaluated using a glacier mass–balance model with a newly improved scheme to track a dusted layer in a snow layer of a glacier. The lowering of surface albedo due to the dusted layer appearing leads to a drastic increase of glacier runoff even under the same meteorological conditions. Calculations of seasonal sensitivity, the rel...
متن کاملa review of luminescence dating of ancient walls and the study of the tammisheh wall
thermoluminescence (tl) dating was established in oxford to fulfil the demand for dating ceramics and other heated man made products (aitken, 1985). it determines the time elapsed since the mineral grains have been heated. following the establishment of tl dating method, it was used to date fired materials such as pottery, flint and etc. optically stimulated luminescence (osl) determines the t...
متن کاملMonumentality in the Mekong Delta: Luminescence Dating and Implications
Brick monuments are one hallmark of emergent political complexity across much of mainland Southeast Asia during the first millennium AD. They first appeared in association with Indic statuary, large nucleated settlements, and the region's earliest states. Chronometric research in the Mekong delta on the earthen and brick wall that surrounds Angkor Borei (southern Cambodia) provides some of the ...
