(U-Th)/(He-Pb) DOUBLE DATING OF DETRITAL ZIRCONS
Geochronology and thermochronology on detrital material provides unique constraints on sedimentary provenance, depositional ages, and orogenic evolution of source terrains. In this paper we describe a method and case-studies of measurement of both U/Pb and (U-Th)/He ages on single crystals of zircon that improves the robustness of constraints in each of these areas by establishing both formatio...

متن کاملControls on erosion intensity in the Yangtze River basin tracked by U–Pb detrital zircon dating
a r t i c l e i n f o The Yangtze River dominates the drainage of eastern Asia, yet the processes that control erosion within the basin are obscure, making the interpretation of the detritus record difficult. In this study we used U–Pb dating of zircon grains from the modern main stream and major tributaries to identify the sources of sediment production, based on the diversity of zircon ages a...
متن کاملA re-evaluation of the origin and setting of the Late Precambrian Hammamat Group based on SHRIMP U–Pb dating of detrital zircons from Gebel Umm Tawat, North Eastern Desert, Egypt
A sample from near the base of the sedimentary Hammamat Group at Gebel Umm Tawat, North Eastern Desert, Egypt, contains detrital zircons with sensitive high-resolution ion microprobe (SHRIMP) U– Pb ages as young as 585 13 Ma. This age is within error of recent SHRIMP dates from the adjacent Dokhan Volcanic Series and establishes that they contributed material to the sediments. It is also c. 45 ...
