Detrital zircon U–Pb geochronology and geochemistry of …

2020-10-9 · Zircon is a common accessory mineral in clastic sediments, which retains U–Pb isotopic signatures during erosion, recycling, and transport; differences in zircon age populations in sediments are linked to the nature and age of source terranes (Ji et al. 2019; Joy et al. 2019; Liu et al. 2019; Chaudhuri et al. 2020).Hence, detrital zircon U–Pb age geochronology is reliable to infer ...

2020-9-23 · In contrast, sedimentary sequences dominated by sandstone could well yield abundant > 60 µ m zircon grains that predate deposition, thereby diluting syn-depositional-age zircon grains. Future attempts to determine depositional ages from fluvial strata should accordingly focus on sequences dominated by fine-grained strata, rather than ...
