Trace elements in tourmalines from massive sulfide deposits and tourmalinites:Geochemical controls and exploration applications
Trace element contents of tourmalines from massive sulfide deposits and tourmalinites have been determined in situ by proton microprobe; >390 analyses were acquired from 32 polished thin sections. Concentrations of trace elements in the tourmalines vary widely, from <40 to 3,770 ppm Mn, <4...

Trace element contents of tourmalines from massive sulfide deposits and tourmalinites have been determined in situ by proton microprobe; >390 analyses were acquired from 32 polished thin sections. Concentrations of trace elements in the tourmalines vary widely, from <40 to 3,770 ppm Mn, <4 to 1,800 ppm Ni, <2 to 1,430 ppm Cu, <9 to 4,160 ppm Zn, 3 to 305 ppm Ga, <6 to 1,345 ppm Sr, <10 to 745 ppm Sn, <49 to 510 ppm Ba, and <3 to 4,115 ppm Pb. Individual grains and growth zones are relatively homogeneous, suggesting that these trace elements are contained within the crystal structure of the tourmaline, and are not present in inclusions. The highest base metal contents are in ore-related tourmaline samples from Kidd Creek (Ontario), Broken Hill (Australia), and Sazare (Japan). Tourmaline data from these and many other massive sulfide deposits cluster by sample and display broadly linear trends on Zn vs. Fe plots, suggesting chemical control by temperature and hydrothermal and/or metamorphic fluid-mineral equilibria.
