Abstract

The mineralogy of olivine veins from the Itkul hyperbasite massif, Southern Urals, has been studied. These veins are composed of forsterite with minor talc, magnetite, and magnesite. Itkul olivine, which was first described in 1847 as a new mineral—glinkite—is forsterite with a fayalite content of 16.5%. It has been established that the metasomatic olivinites of these veins were formed due to recrystallization of host serpentinite under the influence of a nearby granite intrusion. It is suggested that, because of the visual similarity of Itkul forsterite with Ural demantoid, the latter were for a long time called “chrysolites” or “Ural chrysolites.”

南乌拉尔伊特库尔超基性岩群中的福尔斯特石；或者，再谈格林柯尔石

摘要对乌拉尔南部伊特库尔超基性岩群橄榄石矿脉的矿物学进行了研究。这些矿脉由闪长岩和少量滑石、磁铁矿和菱镁矿组成。伊特库尔橄榄石于 1847 年首次被描述为一种新矿物--闪长岩，它是一种闪长岩，其中辉石含量为 16.5%。已经证实，这些矿脉中的变质橄榄石是由于主蛇纹岩在附近花岗岩侵入体的影响下发生重结晶而形成的。有人认为，由于伊特库尔菱锰矿与乌拉尔翠榴石在外观上非常相似，因此后者在很长一段时间内被称为 "翠榴石 "或 "乌拉尔翠榴石"。

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.
