Micro-XRF Studies of Sediment Cores: A Perspective on Capability and Application in the Environmenteothems, cores from peat bogs and river banks and cores collected for environmental forensics and pollution studies. Further, an important cohort of papers has addressed interpretation and calibration issues, increasing the robustness of acquired datasets. In this paper we review marine and lacustri

Micro-XRF Core Scanning in Palaeolimnology: Recent Developments either as a result of evaporative concentration or biological processes (e.g., Ca). Here, we review the use of µXRF core scanning on lake sediments and summarise the range of elements and ratios that have been applied as a reference point for users. We consider some of the challenges involved in in

Micro-XRF Applications in Fluvial Sedimentary Environments of Britain and Ireland: Progress and Prosd is the field of flood reconstruction, 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 potenti

Estimation of Biogenic Silica Concentrations Using Scanning XRF: Insights from Studies of Lake MalawSi record with measured %BSi indicates that calibration parameters can vary with depth in sediment due to changes in chemical and physical characteristics. XRF scanning counting times for Si are evaluated; typically these should be set to allow > 500 counts.

Investigating the Use of Scanning X-Ray Fluorescence to Locate Cryptotephra in Minerogenic Lacustrinand spun in a centrifuge to create a series of 20 laminations in 4 synthetic cores. Rhyolitic and basaltic tephra were added between laminations with different concentrations and using two grain-size ranges (< 53 µm and 105–177 µm). The synthetic cores were split and analyzed on an XRF core scanner,
