Navigating the complexity of detrital rutile provenance: methodological insights from the Neotethys Orogen in Anatolia [PDF]

Geochronology
Sedimentary provenance is a powerful tool for reconstructing convergent margin evolution. However, single mineral approaches, like detrital zircon, have struggled to track sediment input from mafic and metamorphic sources.

Urinary lead in relation to combustion-derived air pollution in urban environments. A longitudinal study of an international panel

Environment International, 2019
Background: Urinary lead (Pb) is generally considered to have limited use in biomonitoring environmental exposure to lead. Carbon load in airway macrophages (AM BC) is an internal marker to assess long-term exposure to combustion-derived aerosol ...

U–Pb ages of angrites

Geochimica et Cosmochimica Acta, 2008
Abstract Precise U–Pb ages, determined with double spike ( 202 Pb– 205 Pb) thermal ionization m1ass spectrometry, are reported for angrites Angra dos Reis (AdoR), Lewis Cliff 86010 (LEW), and D’Orbigny. Nineteen of 23 acid-washed pyroxene fractions from these meteorites and whole rock fractions from D’Orbigny contain between 0.5 and 1.3 pg of total ...
