TLDR
In this paper, the authors measured the d 56 Fe values of bulk granitic and volcanic rocks, as well as magnetite and Fe silicates, and showed that loss of a low-d 56 Fe ferrous chloride fluid is the most likely explanation for the high d 56Fe values in the bulk rocks.About:

TL;DR: In this article, the ages of two highly evolved granitic plutons, Woduhe and Baerzhe, from the Great Xing'an Mountains were constrained at 130±4 Ma for the Wodahe and 122±5 Ma for BaerZhe granites by Rb-Sr and Sm-Nd isotope analyses.

Controls on the fractionation of isovalent trace elements in magmatic and aqueous systems: evidence from Y/Ho, Zr/Hf, and lanthanide tetrad effect
TL;DR: In this paper, the authors investigated the properties of trace elements in aqueous systems and showed that trace element fractionation is not solely dependent on ionic charge and radius, but is also controlled by the electron configuration and the type of complexing ligand, since the latter two determine the character of the chemical bonding in the various complexes.
