摘要
摘要 报告了关于俄罗斯南乌拉尔地区Novoburannoe (Gumbeyskoe)白钨矿氧化矿石中的乌芬石-匍匐石系列矿物的成分和形态的新数据。在与方解石、白云石、黄铜矿和天南星石接触的地方，超生钨矿和含W的硫铁矿沿着含钼白钨矿的裂缝以细脉状复合带状聚集体的形式出现。矿物成分从含钼的 stolzite（Pb0.98Ca0.02）(W0.78Mo0.22)О4 和富含 W 的 wulfenite（Pb0.93Sr0.05Ca0.02）(Mo0.59W0.41)О4 到纯粹的 wulfenite 不一而足。在所研究的样品中，含 W 的硫铁矿占主导地位。不含W的硫铁矿在方铅矿中的辉钼矿包裹体后形成假象。
Stolzite and Wulfenite in the Oxidation Zone of the Novoburannoe (Gumbeyskoe) Deposit (Southern Urals)
Abstract
New data are reported on composition and morphology of wulfenite—stolzite-range minerals in oxidized ores at the Novoburannoe (Gumbeyskoe) scheelite deposit in the Southern Urals (Russia). Supergene stolzite and W-bearing wulfenite occur as veinletlike complex-zoned aggregates along the cracks in Mo-bearing scheelite at the point of contact with calcite, dolomite, chalcopyrite, and tennantite. The mineral composition varies from Mo-bearing stolzite (Pb0.98Ca0.02)(W0.78Mo0.22)О4 and W-rich wulfenite (Pb0.93Sr0.05Ca0.02)(Mo0.59W0.41)О4 to pure wulfenite. W-bearing wulfenite is predominant in the studied samples. W-free wulfenite forms pseudomorphs after molybdenite inclusions in galena.
期刊介绍：
Geology of Ore Deposits is a periodical covering the topic of metallic and nonmetallic mineral deposits, their formation conditions, and spatial and temporal distribution. The journal publishes original scientific articles and reviews on a wide range of problems in theoretical and applied geology. The journal focuses on the following problems: deep geological structure and geodynamic environment of ore formation; distribution pattern of metallogenic zones and mineral deposits; geology and formation environment of large and unique metallic and nonmetallic deposits; mineralogy of metallic and nonmetallic deposits; physicochemical and isotopic characteristics and geochemical environment of ore deposition; evolution of ore-forming systems; radiogeology and radioecology, economic problems in exploring, developing, and mining of ore commodities.
