本文叙述了日本铀矿普查与勘探的简史。描述了人形峠和东浓这两个最有希望的铀矿床。这些矿床是在紧复在白垩纪花岗岩上的晚第三纪底部发现的。关于铀沉积的看法,特别是关于铀的来源问题,一般都认为是由地下水流经含矿花岗岩形成的。本文还简述了独特的丰田矿床。在日本小盆地中已确认的有利标志是:①基底花岗岩中槽状构造的存在(其他国家少见);②晚第三纪中的非海相砾岩沉积。
This article describes a brief history of uranium census and exploration in Japan. Describes the two most promising uranium deposits, the human form and Easton. These deposits were found at the bottom of the late Tertiary in the tight Cretaceous granite. The perception of uranium deposition, especially with regard to the origin of uranium, is generally thought to have been caused by the groundwater flowing through the granitic granites. This article also outlines the unique Toyota deposit. The favorable landmarks identified in the small basin of Japan are: (1) the presence of trough-like structures in the basement granite (rare in other countries); (2) the deposition of non-marine conglomerates in the late Tertiary.
