“…Similarities between the REE contents and patterns in magmatic tourmaline and the whole-rock were documented from granites and orthogneisses worldwide (e.g. Torres-Ruiz et al 2003;Raith et al 2004;Pesquera et al 2005). Based on the experiments, van Hinsberg (2011) determined that the partition coefficients for REE between tourmaline and silicate melt are invariably close to 1 suggesting that tourmaline does not selectively incorporate specific REE into its structure.…”

“…Based on the published data, the absence of any characteristic REE pattern for tourmaline is evident (e.g., King et al 1988;Yavuz et al 1999;Torres-Ruiz et al 2003;Raith et al 2004;Pesquera et al 2005;Ertl et al 2006;Yavuz et al 2011;Čopjaková et al 2013), which indicates that the tourmaline structure does not prefer any specific REE. In tourmalines from granitic pegmatites, extensive variations of La N /Yb N (0.16-433) as well as variable Eu/Eu* (0.005-16) were reported (Jolliff et al 1987;Hellingwerf et al 1994;Roda et al 1995;Ertl et al 2006;Bačík et al 2012).…”

“…Distributions of Y + REE in tourmalines from various geological settings are controlled mainly by the total contents of REE in local rock reservoirs (granitic melt; sedimentary precursor; Torres-Ruiz et al 2003;Raith et al 2004), and/or by the composition of hydrothermal fluids (King et al 1988;Jiang et al 2004;Garda et al 2010;Čopjaková et al 2013). However, the role of associated Y,REE-rich accessory minerals has not been studied.…”

“…It may be also a very useful for provenance studies in sedimentary rocks (Čopjaková et al 2005). Sensitivity of tourmaline trace-element chemistry (including Y + REE) to the composition of its highly variable host rocks (e.g., Torres-Ruiz et al 2003;Raith et al 2004;Pesquera et al 2005;van Hinsberg 2011;this work), makes it a useful tool for interpretation of the growth environment as well as for provenance studies of sedimentary assemblages. However, a combination with the nature, chemistry and crystallization sequence of associated accessory minerals is required to reveal behavior of Y + REE and further trace elements during the tourmaline growth.…”

Tourmalines from NYF and mixed (NYF + LCT) pegmatites of the Třebíč Pluton (Moldanubian Zone, Czech Republic) are generally characterized by variable and relatively high concentrations of Y + REE (4-457 ppm) and Sc (18-765 ppm). They show enrichment in LREE (Ce > La); the chondrite-normalized REE patterns decrease uniformly from La to Tb; Tb to Tm are mostly below the detection limits (< 0.01-0.08 ppm) and are followed by an upturn to Yb and Lu. Our textural and paragenetic observations indicate that growth of magmatic tourmaline reflects Y + REE contents in the melt. Tourmaline is highly compatible with Sc and shows exceptionally high contents of Sc compared to the analyzed host pegmatite units (less than 1 ppm Sc). The contents of Sc positively correlate with ∑Y + REE. Two distinct evolutionary trends of trace-elements in tourmaline were distinguished. (i) A conspicuous increase in Y + REE and Sc in tourmaline (dravite, Ca-rich dravite) from primitive euxenite-type pegmatites reflects their enrichment in the melt with the progressive crystallization and fractionation. It also was enhanced by low P (< 0.02 wt. % P 2 O 5 ) and Ca contents (< 0.8 wt. % CaO) in host pegmatite unit preventing precipitation of Y + REE phosphates and allanite, respectively.(ii) Tourmaline (schorl, fluor-schorl, fluor-elbaite) from more evolved pegmatites (evolved euxenite-type and mixed (NYF + LCT) pegmatite) show a depletion in REE and Sc with progressive crystallization reflecting most likely the coeval precipitation of REE-rich minerals, especially monazite-(Ce), xenotime-(Y), samarskite-and aeschynite-group minerals. The Eu anomalies in tourmaline vary significantly from positive (up to Eu/Eu* ~ 16) to substantially negative ones and are related to the Eu contents in the melt and degree of its fractionation.
