Single-aliquot (U-Th)/He dating of iron-oxides requires less mass and has a higher spatial resolution than the two-aliquot approach, and is, therefore, a more reliable tool for quantifying the time...

Single-aliquot (U–Th)/He dating of hematite has been used to study iron-oxide precipitation in various environments, but we show there is an important challenge to the method: highly retentive hematite samples require temperatures of >1000 °C to b

Oceanic sediments deposited at high rate close to continents are dominated by terrigenous material. Aside from dilution by biogenic components, their chemical compositions reflect those of nearby continental masses. This study focuses on oceanic sedi

An additional method of coupled ESR/U-series dating is developed for teeth showing post-depositional U-loss. The fundamental parameter for the dose rate calculation is the present-day 230Th-activity because of the geochemical immobility of thorium. U
