IODP Expedition 395 Site U1602 X-ray fluorescence (XRF)

Shore-based X-ray Fluorescence (XRF), IODP Expedition 395 Site U1602X-ray fluorescence (XRF) is a rapid, non-destructive technique for determining qualitative and quantitative changes in chemical composition. In the shore-based laboratory at Scripps Institution of Oceanography, University of California, San Diego, an Avaatech XRF Core Scanner was used to measure a large number of spots along the length of a core. Spots are typically irradiated at multiple conditions to excite and measure a wide range of elements. The peak intensity changes (we do not provide concentrations) are then used to help recognize and define major chemo-stratigraphic units without the need for destructive sampling.
