PII S 0016 - 7037 ( 00 ) 00408 - 7 206 Pb – 230 Th – 234 U – 238 U and 207 Pb – 235 U geochronology of Quaternary opal , Yucca Mountain , Nevada
U–Th–Pb isotopic systems have been studied in submillimeter-thick outermost layers of Quaternary opal occurring in calcite–silica fracture and cavity coatings within Tertiary tuffs at Yucca Mountain, Nevada, USA. These coatings preserve a record of paleohydrologic conditions at this site, which is being evaluated as a potential high-level nuclear waste repository. The opal precipitated from gro...
متن کامل(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 کاملAlgorithms and software for U-Pb geochronology by LA-ICPMS
The past 15 years have produced numerous innovations in geochronology, including experimental methods, instrumentation, and software that are revolutionizing the acquisition and application of geochronological data. For example, exciting advances are being driven by Laser-Ablation ICP Mass Spectrometry (LA-ICPMS), which allows for rapid determination of U-Th-Pb ages with 10s of micrometer-scale...
متن کاملLaser microprobe (U–Th)/He geochronology
A new analytical method had been developed to enable high-spatial-resolution (U–Th)/He dating of accessory minerals. It involves the use of a focused ArF excimer to ablate pits in a polished grain surface, with the evolved gases spiked for isotope-dilution measurement of radiogenic He. These data are converted to concentrations by precise measurement of each pit using an optical interferometric...
متن کاملBioaccessibility of U, Th and Pb in solid wastes and soils from an abandoned uranium mine.
Bioaccessible U, Th, Pb and the 238U decay products 214Pb and 210Pb have been determined, using a modified Unified BARGE Method (UBM), in waste solids and soils from an abandoned uranium mine in South West England, UK. Maximum aqua regia extractable concentrations for U, Th and Pb were 16,200, 3.8 and 4750 μg g-1, respectively. 238U had highest activity concentrations near the mine shaft, where...
