... Geology 2022 Economic Geology Tellurium, As, Bi, Sb, and Sn (TABS) are essential components of most platinum group minerals (PGMs) found in magmatic Ni-Cu and platinum group element (PGE) deposits, and hence they may play a role in the formation of these deposits. However, to consider whether...

..., which are generally concordant with the host-rock foliations. The gold-bearing quartz veins have a pronounced Te signature, with a wide variety of tellurides reported ( Bi et al., 2011b ; Jian et al., 2014 , 2015 , 2020 ; Liu et al., 2020 ). Tellurium concentration in the gold ores is typically...

.... Tellurium-bearing minerals commonly form isolated euhedral to subhedral grains or composite grains (up to 525 μm in size) of Ag-, Bi-, Pb-, and Au-rich tellurium-bearing minerals ( e.g ., hessite, tellurobismuthite, volynskite, altaite, and petzite). Panchromatic cathodoluminescence imaging revealed four...

... lingbaoite grain is about 30 × 12 μm in size. At least two stages of gold and telluride mineralization are recognized in the lingbaoite-bearing sample set. The first stage is characterized by the deposition of lingbaoite, native tellurium, and sylvanite, within the commonly observed mineral assemblages...

... obtained according to a standard XRF analysis. Gold, silver, selenium, and tellurium were determined by an ultra-trace ICP-MS method following an aqua regia digestion procedure with the detection limits varying as follows: Au = 0.4 ppb, Ag = 2–10 ppb, Se = 0.04–0.1 ppm, and Te = 0.01–0.02 ppm...

... Forests classifier was refined to not include Au. Tellurium, however, was not omitted from this classifier despite the lack of Te data from SEDEX deposits. The classifier has difficulty identifying orogenic Au mineralization because Te is commonly associated with Au mineralization ( Belousov et al., 2016...

..., 2 to 340 ppm Ag, 2 to 770 ppb Au, and 0.2 to 1000 ppm Cl. Tellurium abundances are highly variable within sulfides, which is likely due to the presence of telluride micro- or nano-phases. Based on morphology, composition, and the absence of monosulfide solid solution, the sulfides are interpreted...
