| 英文摘要 | The shangfanggou mo deposit in henan province is located on the southern margin of north china craton oil the north of the luat chuan fault. the deposit is hosted in luanchuan group. the molybdenum mineralization process can be divided into early, middle and late three stages, which are characterized by assemblages of potassium feldspar-quartz-molybdenite-pyrite, quartzmolybdenite-polymetallic sulfide, and carbonate-quartz-fluorite, respectively. the fluid inclusions in quartz and carbonate can be recognize as three compositional types, i.e., co(2)-h(2)o, h(2)o-nacl and daughter crystal-containg. the primary fluid inclusions in minerals formed in early and middle stages are major of co(2)-h(2)o and daughter crystal-containing types, while those in late-stage minerals only of h(2)o-nacl type. the early-stage fluid is hypothermal (320 similar to 500 degrees c), high salinity (31.75 similar to 66.75 wt% nacl eqv.) and co(2)-rich and belongs to the typical intrusion-related hypothermal system. in middle stage, the fluid system is mesothermal (190 and co(2)-rich and belongs to the typical intrusion-related hypothermal system. in middle stage, the fluid system is mesothermal ( 190 similar to 400 degrees c) middle salinity ( mainly between 2.07 similar to 12.85wt% nacl eqv., minor up to > 30 wt% nacl eqv. and co(2) rich or bearing. the late-stage fluid is a co(2)-poor nacl-h(2)o system with low temperature ( 160 similar to 260 degrees c and low salinity < 4.8 wt% nacl eqv.). fluid holing occurred in early and middle stages, which caused co(2) escape, oxygen fugacity decrease and rapid precipitation of ore minerals fluid boiling is an important mechanism for the mo-mineralization of the shangfanggou mo deposit. |
