摘要: Deciphering the signal within X-ray fluorescence (XRF) core scanner data can be complex in comparison to conventional laboratory XRF analysis where samples are milled and pelleted or beaded. One complicating factor is that down-core variability water content grain-size affect element count rates thereby potentially leading inaccurate interpretations. Experiences using an Itrax highlight some of pitfalls occur when sediment inhomogeneous. We show over a threshold 25 wt.% coarse grained material ( > 63 µm) there potential for causing significant certain elements. It also shown has major effect above 40 %.
