Fractionation of Rare Earth Elements in Greisen and Hydrothermal Veins Related to A-Type Magmatism

Comparison of chondrite-normalized REE concentrations in different sample types in (a) fluorite, (b) epidote, (c) calcite, and (d) chlorite. (e) Chondrite-normalized [40] REE concentrations calculated for bulk vein, the residual remaining after the hypothetical withdrawal of epidote, and the contribution by calcite after epidote withdrawal (the epidote withdrawal and calcite contribution were calculated by multiplying the average REE concentrations for the mineral with its estimated mode in the veins), and (f) REE composition of vein minerals normalized to the estimated mineral mode of the veins.
