“…As it is located on an alluvial fan, detrital influx could strongly dilute the authigenic processes associated with pedogenesis and aggradation of organic matter (Werner and Zedler, 2002. The higher the accumulation rate, the more immature the soils become (Carter et al, 2009;Daniels, 2003), which can explain the low organic matter in the study area. In addition, the majority of sediment is delivered during glacial times, as a result of lowered retainment of the source material on the CLP (Rits et al, 2016).…”

“…In terms of the dynamics of soil development in alluvial settings, a key driver is the balance between processes responsible for the addition of organic matter through biological activity ( melanization) and the build-up of predominantly minerogenic sediment through aggradation ( cumulization) (Carter et al 2009). These influences are schematically illustrated in Fig.…”

Micro-XRF Studies of Sediment Cores

This chapter considers applications of micro-XRF in fluvial depositional environments and presents case-studies from Britain and Ireland in three key river management areas: flood reconstruction; pollution and provenance mapping; and floodplain sediment dynamics. Although fluvial sediment archives are typically shorter and more fragmented than marine and lake sediment records, they do offer significant palaeoenvironmental potential, not least because of the sensitivity of river systems to environmental change. A major consideration in micro-XRF analysis, however, is the continuity and heterogeneity of alluvial sediments and the integrity of accretionary records once they have been subjected to post-depositional processes, such as human disturbance and pedogenesis. Thus far, micro-XRF applications in fluvial environments have been limited. One research area currently being developed is the field of flood reconstruciton, where elements and, in particular, element ratios (e.g. Zr/Rb, Zr/Ti) can be used as particle size proxies. Micro-XRF core scanning technologies allow for analysis at the event-scale, which hitherto has been unachievable in silt and clay sediments. The potential to build and signifcantly enhance our understanding of longer term flooding patterns and non-stationarity, offers considerable scope for augmenting instrumental records and providing new perspectives for contemporary river management. Rapid geochemical assessment of fluvial sedimentary deposits can also be used to support floodplain reconstruction studies and pollution investigations, but greater scope will emerge from the calibration of raw XRF cout data to elemental concentrations. In this paper we demonstrate the potential for using micro-XRF data in sediment provenance investigation, but improvements in error quantification and propagation need to be explored. Given that river alluvium plays an integral role in the cycling and storage of contaminants, further applications in this field would be hugely beneficial for river managers. Although sediment heterogeneity places significant challenges to the quantification of micro-ZRF core scanner results, there has been little attempt to establish what these limitation mean in practical terms
