The National Science Foundation (NSF) awarded a $431,158 Project Grant under the Geosciences program (CFDA 47.050) to the University of Memphis to acquire a micro X-ray fluorescence (μ-XRF) spectrometer. This instrument will be used to measure and map the spatial distribution of plant-essential nutrients, such as phosphorus, calcium, and potassium, in modern and fossil soils. The μ-XRF will also support research in groundwater, sedimentology, and geoarchaeology by mapping chemical changes in minerals from aquifer sediments, flood and lake deposits, ancient river channels, and prehistoric rock quarries. The grant will enable the University of Memphis to establish an Institute of μ-XRF and provide research and training opportunities for up to 150 students in the economically distressed Delta Regional Authority area over the next 3-5 years. This project aims to advance the understanding of how chemical elements are cycled between different Earth systems, which is crucial for predicting system behavior under environmental and climate change scenarios.
