中川岩体位于甘肃省礼县西北约13km处,属秦岭褶皱系的礼县—柞水冒地槽褶皱带西段中部,岩体是以印支期花岗岩为主体,与铀成矿关系较为密切。在中川花岗岩体内产有7902小型铀矿床及多个铀矿化点,其控矿因素多种多样,其富集规律也于各控制因素关系密切。 The Zhongchuan granite is located at about 13km northwest of Li County, Gansu Province. It belongs to the central part of western part of Lixian-Zhashui dolostone fold belt of Qinling fold system. The granite is mainly composed of Indosinian granite, which is closely related to uranium mineralization . There are 7902 small uranium deposits and a number of uranium mineralization sites in the granite body of Zhongchuan. The ore-controlling factors are diverse and the enrichment rules are also closely related to the control factors.
