An improved U-Pb age dating method for detrital zircon by LA-MC-ICP-MS

Detrital zircon U-Pb dating is a powerful tool to trace sources for sedimentary basin and to understand of geological history in structurally complex areas. This study established an analytical protocol for measurement of detrital zircon U-Pb age by LA-MC-ICP-MS. Because detrital zircons normally have a large Pb content variation (several ppm to hundred ppm), which leads to large variations for Pb signal intensity, two sets of detector arrays...
