湖南三二五铀矿床的钾交代与铀矿化

The Relations Between the Metasomatism of K-feldspar and Uranium Mineralization in 325th Uranium Deposit in Hunan Province

三二五矿床是典型的花岗岩型热液铀矿床，钾长石化作用和铀矿化关系密切，钾长石化的结果使得花岗岩的结构疏松，为铀的富集提供了空间。

The No. 325 uranium deposit is a typical granite-typo hydrothermal uranium deposit.The relations between the metasomatism of K-feldspar and uranium mineralization are very close. The metasomatism of K-feldspar makes the structure of granite in the deposit loose and provides wide gaps for the sediment of uranium mineral.
