描述：rmal minerals (quartz. calcite, pyrite and molybdenite)have thrown light on the evolution trend of the molybdenum-bearing hydrothermal system which originatedfrom magmatic processus and underwent significant mixing with meteoric waters in the later stages ofhydrothermal activity.
描述：s the most important molybdenum producer in China.During Yenshanian the Jinduicheng granite porphyry was emplaced in metaspilite of the Proterozoic XiongerGroup,controlled by a NW trending fault Mineral compositions are mainly quartz (25-40％),microclineand microcline perthite(27-40％)and plagioclase(An8-14-,14-32％),associated with minor biotite andmuscovite,a...
