日本的铀矿储量如下表所记。从表中可见,东浓矿山的储量居日本首位,储量为5944吨。东浓铀矿床是以花岗岩为基底的中新世砂砾岩型铀矿床。目前,该矿床外围850平方公里的地区已成为铀普查区。东浓矿床的铀矿物主要有黄绿色的水钠铀矿(Andersonite Na_2Ca(UO_2)(CO_3)_3·6H_2O,三方晶系),含铀沸石、磷灰铀矿、晶质铀矿等。该矿床的月吉矿体的广泛区域勘探阶段已经结束。从1975年开始进行了网度为50米的钻探。迄今
Japan’s uranium reserves are tabulated below. As can be seen from the table, Higuchi’s reserves rank the first in Japan with a reserve of 5,944 tons. The Dongnu uranium deposit is a granite-based Miocene glutenite-type uranium deposit. At present, the 850-square-kilometer area outside the deposit has become a uranium census area. The uranium minerals of Dongnong ore deposit mainly include yellow-green water-sodium uranium deposit (AnO3O_3Ca_3_6H_2O, trigonal system), uranium-bearing zeolites, phosphorite uranium deposits and crystalline uranium deposits. The prospecting phase of the Yueji orebody in this area has come to an end. Drilling with a net of 50 meters started in 1975. so far
