LREE/HREE fractionation is controlled by fluid composition and "mineralogical control". REE patterns of Ca minerals allow to class the reacting fluids in "normal" (Ca/ligand ≫ 1) and "ligand-enriched" (Ca/ligand ≈ 1), the latter being characteristic for remobilization processes. ...

SummaryNormalized REE patterns of aqueous solutions and their precipitates bear information on the physico-chemical environments a fluid experienced during REE mobilization, fluid migration and minerogenesis. Positive Eu and Yb anomalies indicate REE mobilization by a F−-, OH−- and CO32−-poor fluid in a high-temperature …
Bauxite is a non-clastic sedimentary rock, meaning it is not made up of fragments of other rocks or minerals that have been transported and deposited by water or wind. Instead, bauxite is formed through the weathering and …

Anhydrite is a mineral that belongs to the sulfate mineral group. Its name is derived from the Greek words "an" (without) and "hydros" (water), indicating its lack of water content. Anhydrite is composed of calcium sulfate (CaSO4) and is chemically very similar to another well-known sulfate mineral, gypsum (CaSO4·2H2O).
