英文摘要	Scientific deep drilling named ZK01 of Zhuanqiao lies in the centre of Luzong. Based on a series of work, uranium and thorium mineralization is in syenites and monzonites (1500 similar to 1900m) of ZK01 associated with albitization, feldspar, tourmaline and anhydrite. The alteration and mineralization can be divided into five stages, green-tourmaline + feldspar + anhydrite at stage I, pink-tourmaline + anhydrite + uranium-thorium mineralization at stage II, black-tourmaline + anhydrite + uranium-thorium mineralization at stage X, anhydrite + copper + pyrite at stage N and gypsum + calcite + quartz at stage V. Uranium and thorium mineralization are occurred as brannerite, uraninite and uranothorite and formed at stage II and E. The results indicate that the average of homogeneous temperature at stage I is 548. 2 degrees C and salinity is 41. 04% NaCleqv; the average of homogeneous temperature at stage 11 is 339. 6 degrees C and salinity is 10.53% NaCleqv; the average of homogeneous temperature at stage III is 308. 6 degrees C and salinity is 11.48% NaCleqv; the average of homogeneous temperature at stage IV is 183.7 degrees C and salinity is 9.56% NaCleqv; the average of homogeneous temperature at stage V is 133.7 degrees C and salinity is 5.16% NaCleqv. These features mentioned above suggest that the uranium and thorium mineralization are characterized as the hypothermal fluid mineralization and associated with deep syenite and monzonite intrusion by Luo-He fault. Boiling had already occurred several times during ore-forming evolution and may be the dominated factor for metal precipitation. Uranium and thorium mineralization which was discovered and confirmed in the first place provides a new idea for uranium prospecting in Luzong basin.
