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

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

Increases could also be due to flood-induced metal inwash or weathering of bedrock in the catchment. Applic
