Abstract

Oxidation zone of the Yubileinoe massive sulfide deposit, South Urals, is buried beneath Jurassic sediments containing coalified plant remains. Mineralogy of gossan of this deposit is marked by the abundance of siderite. The carbon isotope composition (δ13C) in siderite varies from –20.0 to –23.4‰ PDB, which is close to δ13C variation in coals from the overlying sediments (‒23.5 to ‒26.2‰ PDB). The formation of siderite is likely related to interaction between solutions of the Triassic oxidation zone and fermentation products of the organic matter.

Yubileinoe大型硫化物矿床(南乌拉尔)的戈桑:海底形成的证据

摘要

Yubileinoe大块硫化物矿床的氧化区,南乌拉尔(South Urals),被埋藏在侏罗纪沉积物中,该沉积物中含有碳化的植物残骸。该矿床戈桑的矿物学特征是菱铁矿丰富。碳同位素组合物(δ 13在菱铁矿C)变化从-20.0至-23.4‰PDB,这是接近δ 13从上覆沉积在煤Ç变化(-23.5 -26.2到‰PDB)。菱铁矿的形成可能与三叠纪氧化带溶液和有机质发酵产物之间的相互作用有关。
