Combined µ-XRF and Microfacies Techniques for Lake Sediment Analysespotential of counting varves using the seasonal signature of specific elements is discussed and potential error sources are disclosed by comparison with microscopic varve counts. Detailed grid- µXRF-scanning provides for the first time an insight into the internal structure of varves presented as hi

Experiences with XRF-Scanning of Long Sediment Records different X-ray tube current settings. From the tested normalisation procedures a division of element raw intensities by the intensity of coherent radiation (coh) yielded the best results for elements with mid to high atomic numbers. However, elements with low atomic numbers are less affected by a

Modern Pollution Signals in Sediments from Windermere, NW England, Determined by Micro-XRF and Leadof up-system sediment traps have limited the amount of mining related heavy metals entering Windermere, and as a result, periods of metal workings do not correlate with peaks in heavy metals. Increases could also be due to flood-induced metal inwash or weathering of bedrock in the catchment. Applic

Not only do they rapidly provide important proxy data without damaging samples, but they can obtain environmental data at decadal, annual and even sub-annual scales. This volume will help both experienced and new users of these non-destructive core sca
