Abstract

Loparite is the main placer-forming mineral in placers located along the periphery of the Lovozero alkaline massif. The article presents new materials of the study of loparite from samples taken during field work at the Sergevan site of the Revda placer, located near the northern frame of the massif. The mineral was extracted from the heavy fraction of a technological sample weighing about 30 kg. The paper presents the results of a study of the morphology, features of the chemical composition and internal structure of loparite from placers, as well as its relationship with the bedrock of the massif. Two loparite grains groups were determined: loparite-1, represented by large (0.25–0.75 mm) twins of crystals of regular crystallographic forms, and loparite-2, comprises smaller (0.05–0.20 mm) fragments of irregular shape. The work studied the mineralogical features of each type of grains and revealed their relationship with the bedrock mineralization. The study of the typomorphic features of placer loparite makes it possible to develop an optimal technological scheme for the enrichment of placers to expand the rare metal resource base of Russia

以谢尔盖万矿址为例分析洛沃泽罗矿床群矿床中的绿泥石

摘要洛帕里特是位于洛沃泽罗碱性丘陵外围的块状矿床中主要的块状矿物。文章介绍了研究洛帕里特的新材料，这些材料来自于在位于洛沃泽罗碱性山丘北部框架附近的雷夫达（Revda）块矿的谢尔盖万（Sergevan）矿区进行野外工作时采集的样本。该矿物是从重约 30 千克的技术样本的重馏分中提取的。论文介绍了对块矿中洛帕拉石的形态、化学成分特征和内部结构及其与山丘基岩关系的研究结果。研究确定了两组洛帕拉石晶粒：洛帕拉石-1（由结晶形态规则的大型（0.25-0.75 毫米）孪晶代表）和洛帕拉石-2（由形状不规则的较小（0.05-0.20 毫米）碎片组成）。这项工作研究了各类晶粒的矿物学特征，并揭示了它们与基岩矿化的关系。通过对块状褐铁矿的类型特征进行研究，可以制定最佳技术方案，对块状褐铁矿进行富集，从而扩大俄罗斯的稀有金属资源基础。

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.
