X-ray fluorescence (XRF) core scanning techniques have revolutionized element proxy-based paleo-research over the last decade and has now become an indispensable tool for many research areas. However, despite being fast, non-destructive, and providing records of elemental variations at the submillimeter resolution, science applications of XRF-core scanning results also encounter numerous challenges due to its intrinsically semi-quantitative and ultra-high resolution nature, such as the influences of down-core physical and organic variations, parameter optimizations of machinery, as well as quantitative calibrations and evaluations of the voluminous and complex scanning data. Therefore, the implications of shifts and trends in the elemental data remain challenging to interpret in many settings. 
It is therefore considered timely to bring together international specialists using high-resolution XRF-core scanners in all fields of science to present new research, to stimulate new collaborations and discussions, as well as to propose new technological developments.
