Mercury cycling during the last glacial period in Arctic Lake El'gygytgyn, NE Russia
Journal of Quaternary Science, EarlyView.ABSTRACT Tectonic processes play a key role in the global mercury (Hg) cycle on geological timescales, by mobilising Hg from deep Earth reservoirs to the surface. These natural fluxes also introduce a dynamic component to the terrestrial Hg cycle that can interact with other environmental signals and influence Hg delivery to sedimentary records.
