Abstract
The sediment grain-size effect (GSE), a fundamental factor relevant to the interpretation of elemental concentrations and isotopic compositions, has been normalized using conservative elements such as aluminum (Al), cesium (Cs), and lithium (Li) (C-(Al,C- Cs,C- Li)), which serve as proxies for the natural metal controlling variables of grain size, mineralogy, and organic matter. However, a secondary GSE reportedly remains even after compensation by the Al-normalization procedure, particularly for the concentrations of transition metals (C-T.M). This secondary effect also occurred in the C-(Li,C- Cs)/C-Al ratios of the Korean coastal sediments examined in this study. The primary and secondary GSEs on Cs and Li concentrations can be explained by the quartz-dilution effect and the Cs- and Li-incorporation effect of phyllosilicate minerals, respectively, based on a model involving three component end-members: a Cs and Li-free sand-dominated sediment component consisting mostly of quartz and feldspar, a Cs- and Li bearing silt-dominated component of mica, and a Cs- and Li-enriched clay-dominated component of illite. Although the primary and secondary GSEs on the concentrations of transition metals (particularly Cu and Ni) in coastal sediments might be normalized by dividing the metal concentrations by the square of the Al concentration (C-T.M/(C-Al)(2)), the GSEs can also be normalized by dividing the concentrations by the exact Cs (or Li) concentration (C-T.M/C-Cs).
