俄罗斯在铀矿地质勘查工作中的新动向

尽管俄罗斯是世界铀资源大国，但长期以来国内铀生产不能满足其当前和长期核电发展需求，加上国际铀市场价格近期的不断攀升，俄罗斯对国内铀资源的勘查和开发方针作了一些调整，如：加大探索不整合面型铀矿的力度，积极扩大古河谷型砂岩铀矿的找矿目的层和开辟新区，对以往探明的铀矿床进行经济技术再评价和在已知铀矿带内寻找新的矿集区。同时，为保证上述方针的顺利实施，制定了包括加强区域成矿规律研究在内的科学技术举措。笔在以上论述的基础上对我国今后的铀矿地质勘查工作提出了相应的建议。

Some new tendencies in uranium exploration of Russia

Russia is a country with abundant uranium resources.However,the uranium production in Russia can meet neither the recent nor the long term demands of nuclear power in the country.In addition,the market price of uranium product during the last two years has been going up continuously.The above facts force Russia to adjust its policy for the exploration and the development of uranium resources in the country,such as to strengthen the prospecting and exploration of the unconformity-related uranium deposit,to try to expand new target stratigraphic horizons of paleo-valley type sandstone-hosted uranium deposit and to discover new uranium-mineralized areas,to do economic-technical re-evaluation of previously explored uranium deposits,and to discover new ore-concentrated regions in known U-metallogenic belts.In order to guarantee the successful performance of the above policy,numerous scientific-technological measures have been taken including intensified research on regional metallogeny of uranium.Based on the above situation,the author proposes some corresponding suggestions for uranium prospecting and exploration in China in the future.
