Formation of carbonatite-related giant rare-earth-element deposits by the recycling of marine sediments
Carbonatite-associated rare-earth-element (REE) deposits are the most significant source of the world's REEs; however, their genesis remains unclear. Here, we present new Sr-Nd-Pb and C-O isotopic data for Cenozoic carbonatite-hosted giant REE deposits in southwest China. These REE deposits are located along the western margin of the Yangtze Craton that experienced Proterozoic lithospheric accr...
متن کاملMineralogical Studies in Assisting Beneficiation of Rare Earth Element Minerals from Carbonatite Deposits
Rare earth elements (REE) are either housed in exotic REE minerals that sporadically populate the host rock or they occur as ionic substitutions in the crystal structure of existing rock-forming minerals. The genesis of REEs in carbonatite rocks can result in intricate mineralogical textures between REE minerals, host rock minerals, and minerals formed by later processes. Upfront mineralogical ...
متن کاملEarth Abundant Element Type I Clathrate Phases
Earth abundant element clathrate phases are of interest for a number of applications ranging from photovoltaics to thermoelectrics. Silicon-containing type I clathrate is a framework structure with the stoichiometry A8-xSi46 (A = guest atom such as alkali metal) that can be tuned by alloying and doping with other elements. The type I clathrate framework can be described as being composed of two...
متن کاملMagnetic Phases of Rare Earth Hexagonal Manganites
We describe the magnetic phases of hexagonal rare earth manganites RMnO3 using Landau theory. A minimal model based on four one-dimensional magnetic order parameters is developed.
متن کاملOverland 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...
