Tin contamination in sediments of Lake Zurich: source, spread, history and risk assessment [PDF]
Swiss Journal of GeosciencesIndustrial activities of a silk dyeing factory in Thalwil, on the shore of Lake Zurich, Switzerland, caused extreme Sn contamination of lake sediments. In this study, we determine the contamination source, spread, and age using a multiproxy approach.

Is XRF core scanning a viable method for coral palaeoclimate temperature reconstructions?
Quaternary International, 2019 Abstract The use of X-Ray Fluorescence (XRF) Core Scanning for continuous high-resolution analysis of Sr/Ca in corals is investigated here as a new method for analyzing coral material. Corals are valuable archives for generating high resolution palaeoclimate records of sea surface temperatures of the tropical oceans, but traditional methods of ...

A Stratigraphical-Sedimentological Study of the Last Interglacial Period in the Central Nordic Seas on the Basis of XRF Core Scanning [PDF]
, 2017 The recognition of specific geological time intervals is one of the major issues when establishing the stratigraphies of marine sediment cores. The automatic XRF core scanning method provides a fast and non-destructive method to precisely identify a ...

Journal of Quaternary Science, 2019 Itrax micro X‐ray fluorescence (μ‐XRF) core scanning is a non‐destructive, rapid approach to measuring elemental concentrations and their variability in sediment cores. As such, it records elemental signatures of tephra layers, which serve as correlation

Geophysical Research Letters, 2017 AbstractWe use sediments from a flooded sinkhole (Cenote Jennifer) in northern Cuba to provide new, well‐dated, high‐resolution evidence for the 8.2 kyr event. From ~7600 to 8700 cal yr B.P. the sinkhole contained shallow, low‐salinity water, which supported a marsh dominated by cattail and grass.
