Abstract

Dispersed radioactive ore mineralization (uranium blacks) in paleovalley deposits of the Vitim uranium-ore region (Buryat Republic) has been studied by a set of methods of analytical electron microscopy (SEM, TEM).The ore component, tetravalent uranium phosphate ningyoite, in the form of micrometer crystalline mineraloid precipitations is represented in all kinds of host rocks (sands, bedding granites, overlapping basalts). The previously little known phosphate-black uranium ores are new-for-Russia type of industrial ores.

来自维提姆高原（布里亚特共和国）的黑色磷酸盐铀矿石

摘要

通过一套分析电子显微镜（SEM，TEM）方法研究了维提姆铀矿区（布里亚特共和国）古卵形矿床中的分散放射性矿石矿化（铀黑）。各种基质岩石（砂，层理花岗岩，重叠玄武岩）中都表现出微米级晶体类矿物沉淀的形式。以前鲜为人知的磷酸盐黑铀矿是俄罗斯生产的新型工业矿石。
