Abstract
The Skrytoe deposit (>145 Kt WO3, average grade 0.449% WO3) in the Sikhote-Alin orogenic system (Eastern Russia) is situated in a metallogenic belt of W, Sn-W, Au, and Au-W deposits formed in a late to post-collisional tectonic environment after cessation of active subduction. It is localized within a mineralized district of reduced-type skarn W and veined Au (±W) deposits and occurrences related to the Early Cretaceous ilmenite-series plutonic suite. The deposit incorporates large stockworks of scheelite-bearing veinlets related to propylitic (amphibole, chlorite, quartz) and phyllic (quartz, sericite, albite, apatite, and carbonate) hydrothermal alteration. The stockwork cuts flat-lying mafic volcanic rocks and limestone partially replaced by pyroxene skarn that host the major W orebodies. Scheelite is associated with pyrrhotite and/or arsenopyrite, with minor chalcopyrite and other sulfide minerals; the late phyllic stage assemblages hosts Bi and Au mineralization. The fluid evolution included low-salinity moderate-temperature, moderate-pressure (∼370–390 °C, ∼800 bars) methane-dominated carbonic-aqueous fluids that formed post-skarn propylitic alteration assemblages. Then, at the phyllic stage, there has been an evolution from methane-dominated, moderate-temperature (330–360 °C), low-salinity (<12.3 wt% NaCl equiv.) fluids forming the early quartz-sericite-albite-arsenopyrite assemblage, through lower temperature (290–330 °C) methane-dominated, low-salinity (∼9–10 wt% NaCl equiv.) fluids forming the intermediate quartz-sericite-albite-scheelite-pyrrhotite assemblage, to yet lower temperature (245–320 °C) CO2-dominated carbonic-aqueous low-salinity (∼1–7 wt% NaCl equiv.) fluids forming the late quartz-sericite-sulfide-Bi-Au assemblage. Recurrent fluid immiscibility (phase separation) and cooling probably affected W solubility and promoted scheelite deposition. The stable isotope data support a sedimentary source of carbon (δ13Cfluid = ∼−21 to −10 ‰), a magmatic source for water (δ18OH2O = +7.4 to +7.7 ‰), and dominantly crustal-derived source of sulfur (δ34S = −4.6 to −2.9 ‰) in the hydrothermal fluids. This is consistent with the development of larger, longer crystallizing crustal intermediate to felsic magma chambers in the late to post-collisional tectonic environment, with their protracted magmatic evolution advancing magmatic differentiation and partitioning of W into magmatic-hydrothermal fluid. The dominating role of the crustal-derived magmatic water, sulfur, and carbon appears to be an important feature of reduced W skarn deposits related to ilmenite-series granitoids.

Abstract The Sikhote-Alin Range of the Russian Far East is an important accretionary orogen of the Western Pacific Orogenic Belt. In order to study the formation and tectonic evolution of the orogen, we performed zircon U–Pb dating, as well as geochemical and Sr–Nd–Hf isotopic analyses on 24 granitoid samples from various massifs in the Primorye and Khabarovsk regions. The zircon dating revealed that the granitoids were emplaced from 131 to 56 Ma (Cretaceous to Paleogene). In the Primorye Region...

The results of the study of granitoids from the Kordonnoe scheelite-sulfide skarn deposit in the Malinovka ore field are discussed in this paper. Igneous rocks in the studied area are represented by granites differing in age, which are distinguished in petrography, chemical composition, and thermobarogeochemical characteristics. The genetic relationships of scheelite mineralization to granitoids of the Tatibi Complex are supported by similar REE patterns of granitic rocks and scheelite from ore ...

Abstract The Catface porphyry Cu (Mo–Au) deposit, Vancouver Island, British Columbia was studied to characterize the age, geometry and geochemical affinity of its different intrusive phases, and their tectonic setting. Four different intrusive phases of quartz diorite are broadly calc-alkaline, moderately metaluminous, and have typical arc geochemical affinity. U–Pb age dating of zircons showing two intrusive phases was emplaced at 41.26 ± 0.11 and 41.15 ± 0.10 Ma, and a second two 40.93 ± 0.11 ...

Sulphur solubility and the state of sulphide/sulphate saturation in felsic magmas play an important role in the formation of intrusion-related gold systems. The solubility of sulphur in felsic magmas is mainly controlled by temperature, pressure, redox condition(s), melt composition, and sulphur diffusion, although the sulphur source is considered an essential factor controlling the ultimate sulphide content in the melt. Decreasing temperature and increasing pressure usually result in a decrease...

Vostok-2—East Russia’s largest skarn deposit of high-grade sulfide-scheelite ore with substantial base-metal and gold mineralization—was formed during the Mesozoic orogenic epoch of evolution of the Far East marginal continental system as an element of the gold-tin-tungsten metallogenic belt. The deposit is related to the multistage monzodiorite-granodiorite-granite complex pertaining to the ilmenite series and spatially associated with a minor granodiorite porphyry (?) stock, which bears petrol...

Abstract Experiments were performed to determine the partitioning of molybdenum, tungsten and manganese among a rhyolitic melt (melt), pyrrhotite (po), and an immiscible Fe–S–O melt (Fe–S–O) . Sulfide phases such as these may be isolated from a silicate melt along with other crystallizing phases during the evolution of arc magma, and partition coefficients are required to model the effect of this process on molybdenum and tungsten budgets. We developed an experimental design to take advantage of...

Abstract A field and petro-chemical classification of felsic magmatic phases (FMPs) at the world-class Cantung W skarn deposit was undertaken to document the evolution of magmatism and the relationships between different FMPs, metasomatism, and mineralization. Early FMPs include moderately differentiated (Zr/Hf = 18–26, Ti/Zr = 14–15) biotite monzogranitic plutons and early biotite-rich granitic dykes, and compositionally similar quartz–feldspar porphyry dykes. Late, highly fractionated (Zr/Hf =...

The type examples for the class of deposits termed intrusion-related gold systems occur in the Tombstone-Tungsten belt of Alaska and Yukon, on the eastern side of the Tintina gold province. In this part of the northern Cordillera, extensive mid-Cretaceous postcollisional plutonism took place following the accretion of exotic terranes to the continental margin. The most cratonward of the resulting plutonic belts comprises small isolated intrusive centers, with compositionally diverse, dominantly ...

The Sikhote–Alin accretionary belt along the northwestern Pacific Plate hosts the most important tin province of Russia. Here, more than 500 ore deposits were formed between 105 and 55 Ma at transform and active subduction margins. Petrological models suggest an active role of the mantle in the mineralisation processes. The deposits can be divided into three groups according to their mineral content and associated magmatism. The first group, a cassiterite–quartz group is defined by tin-bearing g...

The Zhuxi W (Cu) skarn deposit is the largest W deposit in the Jiangnan porphyry–skarn tungsten belt in South China, and is also among the largest deposit of this type in the world. Titanite is a common mineral in the Zhuxi deposit, and occurs in three textural settings: titanite I associated with retrograde-altered exoskarn with weak mineralization; titanite II in retrograde-altered endoskarn with disseminated Cu ore; and titanite III from altered granite with disseminated W ore. Here, we prese...

The Dalingshang W-Cu deposit is located in the North section of the Dahutang ore field, northern Jiangxi Province, South China. Vein- and breccia-style tungsten-copper mineralization is genetically associated with Mesozoic S-type granitic rocks. Infrared and conventional microthermometric studies of both gangue and ore minerals show that the homogenization temperatures for primary fluid inclusions in wolframite (~ 340 °C) are similar to those in scheelite (~ 330 °C), but about 40 °C higher than ...

Abstract The Lermontovskoe deposit (∼48 Kt WO 3 ; average 2.6% WO 3 , 0.24% Cu, 0.23 g/t Au) is situated in a W-Sn-Au metallogenic belt that formed in a collisional tectonic environment. This tungsten skarn deposit has a W-Au-As-Bi-Te-Sb signature that suggests an affinity with reduced intrusion-related Au deposits. The deposit is associated with an intrusion that is part of the ilmenite-series, high-K peraluminous granitoid (granodiorite to granite) suite. These rocks formed via mantle magma-in...
