Abstract

New data on the occurrence forms of ore elements were obtained on the basis of the heavy concentrate analysis of material from the thermal sites of Mutnovsky volcano. During the hydrothermal reworking of volcanic rocks and with the participation of magmatic fluids and meteoric waters, metals and metalloids are transported to the surface and are concentrated as the main or impurity components of newly formed minerals. Sulfides of copper, zinc, mercury, silver, and barium sulfate are confidently diagnosed. They contain admixtures of Mn, Cd, Sr, I, Cl, Te, and Pb in addition to mineral-forming Zn, Cu, Hg, Ag, and Ba. Micron-sized phases with Ru, Os and Ir (laurite), and Pb (galena) as the main components and the intermetallic compounds (Fe–Ni), (Fe–Ir–Os), (Pb–Bi), and (Bi–Te), as well as native Au, were revealed. Most of the newly formed mineral individuals are associated with a mineral of the pyrite–marcasite group, which contains impurities of As, Cu, Ni, and Co. Platinoids Os, Ir, and Ru were discovered for the first time among the newly formed minerals within the East Kamchatka Volcanic Belt.

穆特诺夫斯基火山气热活动产物中金属和类金属的赋存形式

摘要

在对穆特诺夫斯基火山热遗址物质的重精矿分析的基础上,获得了有关矿石元素赋存形式的新数据。在火山岩的热液改造过程中,在岩浆液和大气水的参与下,金属和类金属被输送到地表并浓缩为新形成矿物的主要或杂质成分。铜、锌、汞、银和硫酸钡的硫化物可以被自信地诊断出来。除了形成矿物的 Zn、Cu、Hg、Ag 和 Ba 之外,它们还含有 Mn、Cd、Sr、I、Cl、Te 和 Pb 的混合物。以Ru、Os、Ir(月桂石)和Pb(方铅矿)为主要成分的微米级相,金属间化合物(Fe-Ni)、(Fe-Ir-Os)、(Pb-Bi)和(Bi) –Te) 以及原生 Au 均被揭示。大多数新形成的矿物个体与黄铁矿-白铁矿族矿物伴生,其中含有As、Cu、Ni和Co杂质。铂类Os、Ir和Ru是在新形成的矿物中首次发现的位于东堪察加火山带内。
