Late Holocene freshening of the Baltic Sea derived from high-resolution strontium isotope analyses of mollusk shells

, 2011
Strontium isotopic composition (87Sr/86Sr) data from subfossil 14C-dated mollusk shells in raised beach sediments are used as a paleosalinity proxy in the brackish Baltic Sea, the precision (±5%) and accuracy (±0.7‰) of the method being judged from ...

Modern surface sediment diatom assemblages and conductivity modeling in northern China

Ecological Indicators
Despite intensifying climate and anthropogenic pressures on freshwater ecosystems, northern China remains without a regionally calibrated diatom-based electrical conductivity (EC) model hindering efforts to quantify ecological responses across its ...

Lithium occurrence and coal facies control of Longtan formation in Northern Guizhou, China

Frontiers in Earth Science
Coal seams have been recognized as a promising geological reservoir for lithium, and its enrichment is intimately correlated with the original coal-forming parent materials and sedimentary microfacies.

Effects of alkalinity and salinity at low and high light intensity on hydrogen isotope fractionation of long-chain alkenones produced by <i>Emiliania huxleyi</i>

, 2017
. Over the last decade, hydrogen isotope fractionation of long-chain alkenones have been shown to be a promising proxy for reconstructing paleo sea surface salinity due to a strong hydrogen isotope fractionation response to salinity across different ...

Unveiling the paleosalinity constraints on southern peri-Pannonian Lower Miocene lacustrine systems in Serbia and Bosnia and Herzegovina: Lopare (Dinaride Lake System) versus Toplica basin (Serbian Lake System)

Early Neogene saline lakes were widely developed across Central Paratethys, particularly across its „Dinaride-Anatolide“ landbridge (area of Dinarides, Balkans).
