Genesis of the Bieyesamas Monzogranite of the Altay Mountain, Xinjiang, Northwestern China, and Its Rare Metal Resource Potential by Gengbiao Qiao, Xiaoyan Chen, Wenming Li

“…The geochemical analysis shows that the pluton is characterized by high SiO2 (70.45%~75.44%), Al2O3 (14. 04%~17.14%), potassium and alkaline (K2O=4.20%~4.78%, Na2O+K2O=7.90%~8.99%), A/CNK (1.16~1.28), and high corundum (2.33%~5.08%) being found in CIPW standard minerals, belonging to high-K calc-alkaline peraluminous series. …”

Fractionation of Rare Earth Elements in Greisen and Hydrothermal Veins Related to A-Type Magmatism by Mikael Tillberg, Olga M. Maskenskaya, Henrik Drake, Johan K. Hogmalm, Curt Broman, Anthony E. Fallick, Mats E. Åström

“…Low calculated ∑REE concentration for bulk vein (15 ppm) compared to greisen (75 ppm), country rocks (173–224 ppm), and the intruding granite (320 ppm) points to overall low REE levels in the hydrothermal fluids emanating from the granite. …”

Nature and Origin of Mineralizing Fluids in Hyperextensional Systems: The Case of Cretaceous Mg Metasomatism in the Pyrenees by Benoît Quesnel, Marie-Christine Boiron, Michel Cathelineau, Laurent Truche, Thomas Rigaudier, Gérard Bardoux, Pierre Agrinier, Michel de Saint Blanquat, Emmanuel Masini, Eric C. Gaucher

“…Considered as being responsible for the formation of talc, these fluids may be interpreted in several ways: (i) primary brines expelled from Triassic evaporites, (ii) secondary brines produced through halite leaching by diagenetic/metamorphic fluids, and (iii) brines derived from seawater serpentinization of mantle rocks. Stable isotope analyses (δ13C, δ18O, δD, and δ37Cl) and Cl/Br ratio measurements in fluid inclusions and their host minerals were carried out in order to determine the origin of the fluid(s) involved in the formation of the ore deposit. …”
