U-Th-Pb systematics of opaline silica: Implications for the dating of surface processes
U–Pb and U-series analyses of U-rich, relative to both Th and Pb, opal samples using sensitive high-resolution ion microprobe (SHRIMP) demonstrate the ability of this technique for dating opals with ages ranging from several tens of thousands of years to millions of years and from a variety of depos...
