“…Thus, CT oxides could reflect certain control of micas on Ta and Nb fractionation in the parental melt, as suggested by Raimbault and Burnol [82] and Stepanov et al [2] for some granitic melts and Llorens González et al [83] for some Nb-Ta mineralizations from the CIZ. Moreover, average values of the Ta/Nb ratios in Al-micas of barren (0.19), intermediate (0.69) and Li-rich aplite-pegmatites (0.41) from Tres Arroyos [47] would correspond to the trend observed for the Ta/Nb ratios in CT oxides.…”

“…Two types of granites (monzogranite and marginal leucogranite) and three types of aplite-pegmatite bodies (barren, intermediate, and Li-rich) can be found in the Tres Arroyos area (e.g., [11,[46][47][48][49]). These five units display a spatial zonation from the northeastern monzogranite up to the southwestern Li-rich aplite-pegmatites ( Figure 1c).…”

“…Trace elements, including Rb, Cs, Sn, Zn, Ba, Be, Nb, Ta, Zr, Ni, Tl, Pb, P, Sc, V, Ni, Ga, Sr, Y, Zr, Mo, Hf, W, Tl, Th, U and REE, were analysed by Quadropolar Laser-Ablation Inductively Coupled Plasma Mass Spectrometry (LA-Q-ICP-MS) (iCAP-Qc model) in SGIker at the Universidad del País Vasco (UPV/EHU) (see 27 ). The LA-Q-ICP-MS analyses were conducted with a 213 nm New Wave Research UP213 laser coupled with a Thermo Fisher Xseries-II ICP-MS with an Xt interface and a shielded plasma torch using the NIST SRM 612 glass for tuning.…”
