Última Correction of interstitial water changes in calibration methods applied to XRF core-scanning major elements in long sediment cores: Case study from the South China Sea ArchiMer Chen, Quan; Kissel, Catherine; Govin, Aline; Liu, Zhifei; Xie, Xin. Fast and non-destructive X-ray fluorescence (XRF) core scanning provides high-resolution element data that are widely used in paleoclimate studies. However, various matrix and specimen effects prevent the use of semi-quantitative raw XRF core-scanning intensities for robust paleoenvironmental interpretations. We present here a case study of a 50.8-m-long piston Core MD12-3432 retrieved from the northern South China Sea. The absorption effect of interstitial water is identified as the major source of deviations between XRF core-scanning intensities and measured element concentrations. The existing two calibration methods, i.e. normalized median-scaled calibration (NMS) and multivariate log-ratio calibration (MLC), are tested with this sequence after the...
