Overland Flow Using Rare Earth Element
14 15 Rare earth element oxides (REOs) have excellent potential for use as tracers in 16 erosion studies. Using laboratory and field experiments we aimed to develop and test 17 a simple application method for spreading REOs and to use REOs to determine the 18 source of sediment to concentrated overland flow paths. 19 Tracks left by farm machinery (tramlines) in fields act as concentrated flow 2...
متن کاملGeochemical Triggers of Arsenic Mobilization during Managed Aquifer Recharge.
Mobilization of arsenic and other trace metal contaminants during managed aquifer recharge (MAR) poses a challenge to maintaining local groundwater quality and to ensuring the viability of aquifer storage and recovery techniques. Arsenic release from sediments into solution has occurred during purified recycled water recharge of shallow aquifers within Orange County, CA. Accordingly, we examine...
متن کاملEvidence for a Distinctive Rare Earth Element-enriched Mantle Reservoir on Mars
Introduction: At least three major geochemical reservoirs have been identified in the crust-mantle system of Mars, including the primitive mantle, an ancient highly depleted mantle, best sampled by the most LREE-depleted basaltic shergottites, and an ancient enriched crust [e.g., Refs. 1-4]. Some workers, evaluating both isotopic and geochemical data, have suggested additional reservoirs, for e...
متن کاملRare earth element oxides for tracing sediment movement
The development of soil conservation plans and evaluation of spatially distributed erosion models require knowledge of rates of soil loss and sedimentation on different landscape elements and slope positions. Characterization of soil erosion rates and patterns within watersheds is important for the understanding of erosion processes and landscape evolution. Experimental data that show spatial t...
متن کاملBiotechnology Processes for Scalable, Selective Rare Earth Element Recovery
Biorecovery of rare earth elements (REE) from wastes and ores is achieved by bacteria using biogenic phosphates. One approach uses an enzyme that biomineralises REE phosphate crystals into the extracellular polymeric matrix (EPM). The enzyme, co-localised in the EPM, provides a continuous phosphate feed into biomineralisation. The bacteria can be immobilised in a column, allowing continuous met...
