| Abstract: | The two uranium mineral-deposits of 721-2 and 721-18 in northern part of Xianshan uranium mineral deposits are 1.5 km far from each other. The mineral-bodies of the two mineral deposits are mainly existed in the contacting zone of granite-porphyry and adjoining rock. The two small rock-masses of granite-porphyries formed in Yanshan period are formed through anatexis of base shallow metamorphic-rock of Sinian System. The two small rock-masses of the same source intrude upward along the intersection parts of base fissure when the granite-porphyry develope structure coincided and threaded together with the base high angle, endowed uranium ore-bodies develope in it through strong sodium metasomatism. |
