摘要

摘要:乌拉尔中部沙布罗夫斯基地区的卡门努泽尔斯科产状脉状切割铬铁矿中的ourmaline、金红石及其伴生矿物具有一定的特征。电气石属钛氧钛钛系列，含Cr (0.52 ~ 2.06 apfu)、Ni (0.03 apfu)和V (0.02 apfu)。拉曼光谱分析表明电气石中含有Fe3+。金红石与电气石伴生物的wt %分别为:Sb2O5 4.68 ~ 11.69, Cr2O3 2.00 ~ 8.02, WO3 0.88 ~ 1.14。认为电气石及其伴生矿物是在氧化条件下形成的。

Abstract

Tourmaline, rutile, and associated minerals from veinlets cutting chromitites are characteristic of the Kamennoozerskoe occurrence belonging to the Shabrovskii district in the Central Urals. Tourmaline belongs to the dravite–oxy-dravite series and contains Cr (0.52–2.06 apfu), Ni (up to 0.03 apfu), and V (up to 0.02 apfu). Raman spectroscopy indicates Fe³⁺ in tourmaline. Rutile associated with tourmaline contains, wt %: Sb₂O₅ 4.68–11.69, Cr₂O₃ 2.00–8.02, and WO₃ 0.88–1.14. It is suggested that tourmaline and associated minerals were formed under oxidizing conditions.
