“…Série Científica Beaty et al (1987), Hellingwerf et al (1994), Slack (1996) e Griffin et al (1996) reforçam a existência da correlação entre turmalina rica em Mg e depósitos de sulfetos, o que pode constituir um guia em trabalhos de exploração mineral. Griffin et al (1996) destacam que certos elementos traços presentes em turmalina (Cu, Pb, Zn, Sn, Ba, Sr e Ga) são também diagnósticos do tipo de depósito de sulfeto maciço.…”

“…The first, with a concave, lies from Cu to Pb and the second plots in a similar manner from Zn to Pb (Figure 9(c)). The Pb -Zn -Cu contents of tourmalines from the Asarcık area probably cannot be directly correlated with tourmalines in massive sulphide deposits (Griffin et al 1996), but base metal proportions in tourmalines from the study area are generally related to the metallogeny of the Pb and Zn ores.…”

“…Trace element contents in tourmaline may reflect its associated ore deposits. For example, Griffin et al (1996) in an attempt to separate potentially ore-related tourmalines from those barren tourmalines in massive sulphide deposits and tourmalinites. Tourmalines associated with the Asarcık granitoid and the quartz veins are shown on various ternary diagrams in Figure 9.…”

“…Concentration level of the Pb and Zn in tourmalines from the fresh and less-altered Asarcık granitoid and the quartz veins on log Pb versus Zn plot shows a general increase with increasing Zn content (Figure 10(a)). The Pb contents of tourmalines are, in general, higher than those of tourmalines from different geological environments including massive sulphide deposits (Taylor and Slack 1984;Griffin et al 1996), gold deposit (Jiang et al 2002), metamorphosed evaporates and associated tourmalines (Jiang et al 1997), porphyry Cu -Mo deposit (Yavuz et al 1999a), tin deposit (Jiang et al 2004), tourmaline-rich rocks (Pesquera et al 2005), and pegmatites (Roda-Robles et al 2004). Plots of log Pb versus Cu show no distinctive variation (Figure 10(b)), but contents of Pb and Cu in tourmalines from the fresh and less-altered Asarcık granitoid and tourmalines in the quartz veins display a positive correlation (r ¼ 0.92 and 0.83, respectively).…”

This paper reports trace-element, rare-earth element (REE) and boron isotopic compositions of tourmaline in the Asarcık granitoid and quartz veins at Şebinkarahisar. Abundant tourmaline occurs in the vein-type Pb-Zn-Cu^U deposit, within the northeastern Pontide Metallogenic Belt, both within the Late Cretaceous Asarcık granitoid and in associated quartz-tourmaline veins. Tourmaline in the granitoid forms as rosettes up to 1.5 cm in diameter, whereas in quartz-tourmaline veins a few centimetres to a few metres wide, it occurs as black needles and masses that cut the pluton. We present a systematic geochemical study of these tourmalines -all of the schorl-dravite series. Tourmalines from the quartz veins contain high concentrations of ore metals such as Ag, Bi and Zn and have higher Sr, Cr and Sn contents than tourmalines in the Asarcık granitoid. Tourmalines from intensively altered parts of the pluton are characterized by higher concentrations of trace elements such as Ba, Rb, V, Sc, Th and Zr compared with occurrences in the quartz veins and in the fresh and less-altered granitoid. Chondritenormalized patterns of REEs in tourmalines from the Asarcık granitoid are generally similar to those of tourmalines in the quartz veins. All vein tourmalines, however, are characterized by heavy REE enrichments, in sharp contrast to those in the granitoid. Boron isotopic compositions of tourmalines range from 214.0 to 22.2‰ and fall within the d 11 B range of this mineral in granite-related settings. Tourmaline rosettes from the Asarcık granitoid show relatively lighter d 11 B values (214.0 to 212.2‰) in comparison with those in the quartz veins (210.4 to 22.2‰).

Chemical composition of tourmaline in orogenic gold deposits

Tourmaline from eighteen orogenic gold deposits and districts, hosted in varied country rocks and metamorphic facies, was investigated by EPMA (Electron Probe Micro-Analyzer) and LA-ICP-MS (Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry) to establish discriminant geochemical features to constrain indicator mineral surveys for gold exploration. Such tourmaline most commonly belongs to the alkali group, with a dravitic composition. LA-ICP-MS results were investigated with binary plots and PLS-DA (Partial Least Square-Discriminant Analysis). PLS-DA suggests that the major element composition of tourmaline from orogenic gold deposits is buffered by the hydrothermal fluid, whereas trace element composition is strongly controlled by the composition and the metamorphic facies of the country rocks. Contents of Sn, Ga, Ti, Rare Earth Elements (REE), Zr, Hf, Nb, Ta, Th and U vary with the metamorphic facies of the country rocks. Tourmaline from orogenic gold deposits has high contents of Sr, V, and Ni and low Li, Be, Ga, Sn, Nb, Ta, U, and Th compared to tourmaline from other deposit types and geological environments. Binary plots such as Sr/Li vs. V/Sn, Sr/Sn vs. V/Nb, Sr/Sn vs. Ni/Nb and Sr/Sn vs. V/Be, as well as PLS-DA, discriminate tourmaline from orogenic gold deposits from that of other settings. Binary plots highlight a transitional variation in the trace element composition of tourmaline from metamorphic, to magmatic-hydrothermal, to magmatic environments.
