| 英文摘要 | Nianzigou Mo deposit is a typical quartz vein deposit in Xilamulun molybdenum metallogenic belt, Inner Mongolia. Its major molybdenite ore bodies are controlled by fault structures within the Yanshanian medium-coarse biotite monzogranite. Fluid inclusion studies show that W(L) (5% similar to 20%) type and W(V) (20% similar to 50%) type liquid-vapor inclusions are hosted in vein quartz. Fluid of the early stage is characterized by low temperature (89. 3 similar to 245. 2 degrees C), middle-low salinities (2. 07% similar to 17. 96% NaCleqv). The ore-forming fluid in the main mineralization stage is characterized by epithermal (134. 4 similar to 458. 8 degrees C, most values in the range of 170 similar to 240 degrees C), middle-low salinities (0. 53% similar to 19. 92% NaCleqv). The late mineralization fluid is characterized by low temperature (134. 9 similar to 202. 4 degrees C), middle-low salinities (4. 96% similar to 14. 97% NaCleqv). The molecule composition includes H(2)O(> 96. 1 mol%), CO(2) N(2), CH(4), C(2)H(6) Ar, H(2)S, and the ion composition are mainly Na(+), SO(4)(2-), Cl(-). These indicate the ore-forming fluids have the composition of NaCl-H(2)O system. Hydrogen and oxygen isotopes of fluid inclusions in various mineralization stages are -128. 821% similar to -109. 234 parts per thousand and -5. 75 parts per thousand -1. 90 parts per thousand, and these indicate that the solutions were originated from magmatic water and meteoric water. Open fracture system created conditions for fluid mixing which caused the deposition of Mo. These characters are different from the high salinity porphyry deposit, and the mechanism for ore-metals precipitation is fluid-boiling in porphyry deposit. |
