序言大家知道,日本的铀矿床情况在近两三年内有了很大变化。假如与1954年按照原子能预算国家开始进行调查时比较,情况新然可观。这就是,不但陆续发现40余个当时完全不知其存在的含铀热液矿床-主要是矿脉型矿床,而且还在当时没有预料到的第三系地层中发现了10个以上的含铀层赋存地区(如图1所示)。对于前者之矿脉型矿床,虽然在矿床地质学上发现一些有趣现象,并获得了一
As we all know, Japan’s uranium deposit situation has changed a lot in the past two or three years. If compared with the 1954 survey conducted by the countries that started the atomic budget, the situation is quite impressive. That is, instead of discovering more than 40 uranium-bearing hydrothermal deposits, mainly vein-type deposits, which were completely unknown at that time, more than 10 uranium-bearing layers were found in the unpredictable Tertiary strata at that time Deposit area (as shown in Figure 1). For the former vein type deposit, although some interesting phenomena have been found in the deposit geology and obtained a
