摘要
Maoling gold deposit is hosted in the Second Member of Gaixian Formation, which is mainly phyllonitized sericite phyllite with interbed sericite quartzite. Four altered zones with gold mineralization are delineated. Gold is mainly hosted in arsenopyrite, pyrrhotite, pyrite and minor in galena and quartz. Ore δ ( 34 S) is characterized by concentrating heavy sulfur. δ ( 18 O) and δ (D) of fluid inclusions in quartz have the same ranges as those in wall rocks, suggesting that metamorphic hydrothermal solution and meteoric water may be involved in the formation of the deposit. Moreover, deep faults and that some deep derived ore forming materials seem to play more important role.
