Description :
+The results of a luminescence dating program involving 78 samples of material from 9 sand ramp complexes have enabled recognition of regional and local patterns of sand accumulation in the Eastern Mojave Desert. The study area extends from Lake Manix, in the west, to the Colorado River, in the east. The periods of accumulation have been identified on the basis of quartz TL dating, and potassium feldspar TL and IRSL dating. The continuity of sand supply to potential deflation areas is seen as a critical condition for accumulation of material on the sand ramps during the Late Quaternary in the Eastern Mojave.
