里采夫地区为科拉半岛上铀矿最有价值的地区之一。这里共发现了一处矿床(里采夫矿床),5个大矿点(极地、陡崖、野湖、岸边、柯什卡牙伏尔)以及约40个其他铀矿化点。本文描述了里采夫地区地质,并介绍了该区内所发现的铀矿化的富集条件、构造和矿物成分特征等。铀矿化可划分为5种类型:(1)伟晶质花岗岩和石英-斜长-正长代岩中与奥长岩中的稀土-钍-铀矿化;(2)产于石英-钠长石-微斜长石交代岩中和石英-微斜长石交代岩中的钍-铀矿化;(3)产于绿泥石-钠长交代岩中与钠长岩中的铀矿化;(4)产于钠长石-水云母-绿泥石交代岩中的铀矿化;(5)产于陆相岩石中的稀土-磷-铀矿化。对于铀矿化与早、晚期卡累里早期活化作用以及与波罗的地盾海西期岩浆构造活化作用的联代关系的见解作了论证。
The Ritsev region is one of the most valuable uranium deposits on the Kola Peninsula. There were a total of one ore deposit (Ritivu deposit), five major ore points (polar, steep cliffs, wild lakes, shore, Koshkar Volta) and about 40 other uranium mineralization sites. This paper describes the geology of the Ritzeff region and presents the enrichment conditions, tectonic and mineral composition characteristics of uranium mineralization found in the area. Uranium mineralization can be divided into five types: (1) rare earth-thorium-uranium mineralization in Pegmatitic granites and quartz-plagioclase-orthograde and anorthite; (2) (3) Thorium-uranium mineralization in the feldspar-micropanite metasomatism and quartz-micro plagioclase interpreted rocks; (3) uranium mineralization in albite-albite and albite ; (4) uranium mineralization occurring in albite-aquifer-chlorite metamorphic rocks; and (5) rare earth-phosphorus-uranium mineralization in continental rocks. Demonstration on the relationship between uranium mineralization and early and late Kareri activation and the association with the Hercynian magmatic tectonic activation in the Shield Earthquake.
