“…Therefore the host volcanic rocks and Sandaowanzi monzogranite probably have no genetic relationships with the Au-Ag-Te mineralization. Moreover, the diabase dykes which intrude the ore veins and postdate the ore formation were dated in the range of 118 ± 1 to 115 ± 1 Ma (zircon U-Pb ages, Liu et al, 2011;plagioclase 40 Ar/ 39 Ar ages, Zhao et al, 2013). Collectively, based on the current evidences, a geochronological framework for the Sandaowanzi ore district may be developed (Fig.…”

“…Other notable modern and historic gold deposits carrying significant amounts of the gold as tellurides include Cripple Creek, Colorado (~875 tons gold) [2]; Emperor, Fiji (~360 tons of gold, 10-50% occurring as tellurides) [3,4]; and Sǎcǎrîmb, Romania [5]. Another important example is the recently discovered Sandaowanzi gold deposit on the northeastern edge of the Great Xing'an Range, Heilongjiang Province, North East China, with a total reserve of ≥25 tons of gold and an average grade of 15 g/t [6][7][8][9]. We believe that this is the first case of a major gold deposit in which the gold telluride minerals are the dominant ore, with more than 95% of recovered gold occurring as tellurides.…”

Gold–(silver) telluride minerals constitute a major part of the gold endowment at a number of important deposits across the globe. A brief overview of the chemistry and structure of the main gold and silver telluride minerals is presented, focusing on the relationships between calaverite, krennerite, and sylvanite, which have overlapping compositions. These three minerals are replaced by gold–silver alloys when subjected to the actions of hydrothermal fluids under mild hydrothermal conditions (≤220 °C). An overview of the product textures, reaction mechanisms, and kinetics of the oxidative leaching of tellurium from gold–(silver) tellurides is presented. For calaverite and krennerite, the replacement reactions are relatively simple interface-coupled dissolution-reprecipitation reactions. In these reactions, the telluride minerals dissolve at the reaction interface and gold immediately precipitates and grows as gold filaments; the tellurium is oxidized to Te(IV) and is lost to the bulk solution. The replacement of sylvanite is more complex and involves two competing pathways leading to either a gold spongy alloy or a mixture of calaverite, hessite, and petzite. This work highlights the substantial progress that has been made in recent years towards understanding the mineralization processes of natural gold–(silver) telluride minerals and mustard gold under hydrothermal conditions. The results of these studies have potential implications for the industrial treatment of gold-bearing telluride minerals.

“…This area records evidence for several regional tectonic events, including the collision between the Songnen and Bulieya–Jiamusi massifs (Neoproterozoic–Early Cambrian), the Xing'an and Erguna massifs (Early Palaeozoic), the Songnen and Xing'an massifs (Late Palaeozoic), and the North China Plate and the Mongolian Xing'an Massif (Late Palaeozoic; She et al, ; Zhang et al, ; Zhou, Simon, Wilde, Ren, & Zheng, ). The intrusive rocks in this area have complex petrogenesis and geochemical characteristics and have therefore been the subject of numerous studies (e.g., Ge et al, ; Jia, Wei, Gong, & Zhao, ; Liu et al, ; Ouyang, Mao, Zhou, & Su, ; Zheng, Zhang, & Xu, ).…”

The occurrence of igneous rocks within the Wenkutu area, northeastern China, allows the Late Palaeozoic–Mesozoic geodynamic setting of the Great Xing'an Range to be investigated. Here, we present petrographic, geochemical, and geochronological data for intrusive rocks within the Wenkutu area. Zircon U–Pb geochronology reveals that magmatism occurred during the Early Carboniferous (ca. 334 Ma), Early Permian (ca. 296 Ma), Middle Jurassic (ca. 170 Ma), and Early Cretaceous (ca. 130 Ma). The Early Carboniferous intrusive rocks are intermediate–mafic, metaluminous, and medium‐K calc‐alkaline, have low SiO2 (49.57–55.00 wt.%) and high MgO (3.00–4.77 wt.%), Cr (average 60.64 ppm), and Ni (average 24.73 ppm) contents, and high Mg# (average 45.1) values. These features, together with their significant depletion in Nb, Ta, and Ti, and their enriched Sr–Nd isotopic compositions, suggest that these Early Carboniferous rocks were derived from the mantle and subsequently contaminated by crustal material. The Early Permian, Middle Jurassic, and Early Cretaceous intrusive rocks are intermediate–acidic, peraluminous, and high‐K calc‐alkaline, enriched in light rare‐earth elements, Rb, Th, U, K, P, and Hf, relatively depleted in heavy rare‐earth elements, Nb, Ta, and Ti, and have Eu/Eu* values of 0.05–0.86. These features indicate that the rocks were derived by the partial melting of lower crust. Our results, together with those of previous studies, suggest that the Late Palaeozoic intrusive rocks formed during collision between the Songnen and Xing'an massifs. The Early Permian intrusive rocks formed during the transition from an orogenic to a non‐orogenic environment. The Middle Jurassic intrusive rocks formed during the closure of the Mongol–Okhotsk Ocean (MOO) and were emplaced along the western part of the suture zone. The Early Cretaceous intrusive rocks formed during non‐orogenic extension and were related to the final closure of the MOO or to rollback of the Palaeo‐Pacific Plate.
