英文摘要Variability in detrital trace-metal (TM) concentrations adversely affects the accuracy and uncertainty of using TM concentrations in siliciclastic marine sediments to decipher paleoceanographic conditions. Here we analyze massive TM datasets for rocks, soils, and stream sediments collected across the conterminous United States to quantify the effects of weathering and fluvial transport on the concentrations and variabilities of commonly used TMs (Al, Ti, Ba, Cr, Fe, Li, Ni, U, V) in detrital materials. Titanium (Ti) is preferred as the normalization element due to its lower mobility compared to aluminum (Al). Median TM/Ti ratios decrease by up to 25% from solid rocks to fluvial sediments, while standard deviations (SD) decrease by up to 90%, indicating that weathering and fluvial transport reduce not only TM/Ti ratios but also their ranges of variation. At a regional scale, median TM/ Ti ratios in soils and sediments deviate significantly from commonly used global standards (Post-Archean Australian Shales and Upper Continental Crust). This means that, for normalization purposes, it is necessary to constrain the detrital TM/Ti ratios for each drainage basin under study rather than making use of a global standard. Sensitivity analyses demonstrate that the modification of median TM/Ti by weathering and fluvial transport processes can lead to significant systematic errors in detrital-corrected TM concentrations. Although weathering and fluvial transport can significantly reduce the variabilities of detrital TM/Ti ratios, the remaining variance is still significant and should be propagated into uncertainties in the corrected TM concentrations.
