摘要
位于俄罗斯外贝加尔地区的斯特列措夫铀矿田为世界上最大的火山岩型铀矿田,也是俄罗斯最大的铀资源所在地。研究表明,斯特列措夫诸多铀矿床铀源主要源于组成破火山口地层大约1/3的强烈蚀变的流纹岩和由海西期黑云母花岗岩构成的破火山口基底。华南地区为我国重要的热液型铀矿床产地,斯特列措夫铀矿田铀源的研究对我国华南地区开展铀矿找矿勘探工作和成矿研究具有一定的指导意义。
Uranium deposits in Streltsovka caldera （Transbaikalia, Russia）of Late Jurassic are both the largest uranium field associated with volcanics in the world and Russia＇s largest uranium resources base. Uranium sources of Streltsovka orefield are from strongly altered rhyolites which constitute about one third of the caldera stratigraphic pile and Hercynian biotite granites which make up the caldera basement. South China is the important productive base of hydrothermal uranium deposits in China. The study on uranium sources of Strehsovka uranium orefield is of certain indicating significance for uranium research and prospecting in South China.
