Hyperaridity is the vital factor in pavements surviving for years or more, aided by minimal bioturbation and clast-size reduction. This chapter presents examples of a variety of applications of U-series to geochronology of magmas and volcanic rocks. Volume 90, Number Sign up.
These two parent isotopes have different decay chains.
Uranium-series (U-series) dating method
This paper integrates prior scholarship on desert pavements with a case study of pavements on stream terraces in the Sonoran Desert to analyze the processes and site conditions that facilitate the survival of ancient desert pavements. Close Modal. The age could be similar to the age of the death of the fossil - if the uptake occurred right after the death of the organism. Forty U-Th dates on pedogenic carbonate confirm the utility of the technique for dating late Pleistocene alluvium in arid regions and suggest that age variation among late Pleistocene fans grouped on the basis of soils and geomorphic criteria may be significant.
