Using the U-Pb system of calcretes to date the time of sedimentation of clastic sedimentary rocks

The time of sedimentation of rapidly deposited clastic sedimentary rocks in fluvial environments may be directly dated with an uncertainty of less than three million years using U-Pb dating of pure micritic calcite from calcretes developed in overbank deposits. This conclusion is based on results ob...
