加拿大、澳大利亚铀矿勘查活动的特点及其成功经验

自上世纪80年代中期以来，世界铀市场就一直处于低迷状态，极大地影响了世界铀矿勘查的投入和勘查成果。但是加拿大、澳大利亚这2个世界上铀资源大国和产铀大国在此期间在铀矿勘查上仍取得不小的进展。究其原因是2个国家都坚持把铀矿勘查工作的重点放在已知成矿单元和初步查明的远景区，把勘查的目标矿床类型锁定在成矿单元内成熟的矿床类型，并长期不懈地投入工作量。我国的铀矿勘查正处于新的发展时期，借鉴他们的成功经验应当是有益的。

Features of uranium exploration in Canada and Australia and its successful experiences

Since the middle of 1980's the world uranim market has been being reduced greatly effecting the uranium exploration investment and the achievements.However,Canada and Australia being the most important U-resources,and U-producing countries in the would have made significant progresses in uranium exploration during this period.The main reasons for this are:the two countries insist on concentrating the exploration work in known metallogenic units(provinces,belts,zones)and preliminarily determined perspective areas,on regarding the matural deposit type as the prospecting target,and on unremitting investment for uranium exploration in these areas.The uranium exploration is under the new development in China and it seems to be necessary and benefical to use their successful experiences for reference.
