摘要
SHRIMP U-Pb dating of diagenetic xenotime from sedimentary rocks has provided age constraints for sedimentary diagenesis （McNaughton et al., 1999; Fletcher et al., 2000; England et al., 2001; Rasmussen et al., 2004; Vallini et al., 2007）. Xenotime （YPO4） may grow during early diagenesis, typically being present as a trace constituent in siliciclastic sedimentary rocks （Rasmussen, 2005）, in the form of syntaxial outgrowths on detrital zircon grains. Diagenetic xenotime occurs in a wide variety of rock types, including conglomerate,
