Nano-Magnetite Aggregates in Red Soil on Low Magnetic Bedrock, Their Changes During Source-Sink Transfer, and Implications for Paleoclimate Studies
(Journal of Geophysical Research: Solid Earth, 2020)Soil and lake sediments are important paleoclimate archives often forming a source-sink setting. To better understand magnetic properties in such settings, we studied red soil on low-magnetic bedrock and subrecent sediments ... -
Precipitation and Lake Water Evaporation Recorded by Terrestrial and Aquatic n‐Alkane δ2H Isotopes in Lake Khar Nuur, Mongolia
(Geochemistry, Geophysics, Geosystems, 2022-02-17)The compound‐specific hydrogen isotopic composition (δ2H) of n‐alkanes is a valuable proxy to investigate hydrological conditions in lake sediments. While terrestrial n‐alkanes reflect the isotopic signal of the local ... -
The spatial distribution of sedimentary compounds and their environmental implications in surface sediments of Lake Khar Nuur (Mongolian Altai)
(Earth Surface Processes and Landforms, 2021-01-26)Lake sediments are valuable natural archives to reconstruct paleoclimate and paleoenvironmental changes which consist of inorganic and organic sediment compounds of allochthonous origin from the catchment and of autochthonous ... -
What Can We Learn From X-Ray Fluorescence Core Scanning Data? A Paleomonsoon Case Study
(Geochemistry, Geophysics, Geosystems, 2020)X-ray fluorescence (XRF) core scanning of marine and lake sediments has been extensively used to study changes in past environmental and climatic processes over a range of timescales. The interpretation of XRF-derived ... -
Why productive lakes are larger mercury sedimentary sinks than oligotrophic brown water lakes
(Limnology and Oceanography, 2020-12-25)Mercury accumulation in lake sediments is a widespread environmental problem due to the biomagnification of Hg in the aquatic food chain. Soil Hg concentrations, catchment vegetation, erosion, and lake productivity are ...
