| 英文摘要 | The songhu iron deposit is located in the eastern part of awurale region, and its bed-like orebodies occurred in the voleanic-pyroclastic rocks of the lower carboniferous awurale formation. the volcanic rocks, as the wall/host rocks of the deposit, were formed in an island arc tectonic setting according to their trace element geochemistry. three genetic types of pyrite have been distinguished in the deposit: the framboidal, the anhedral-subhedral ( with a large amount of pyritized bio-remains), and the cobalt pyrite. the pre-iron ore framboidal pyrite of sedimentary origin recrystallized due to the reworking of ore-forming hydrothermal solution, accompanied by the apparent increasing of its co content and co/ni ratio. the iron ore-stage anhedral-subhedral pyrite and associated pyritized bio-remains possess relatively higher co contents and co/ni ratios, indicating the close relationship between the ore-forming fluid and the magmatic (volcanic) activities. the songhu iron deposit was superimposed by late stage cu-co mineralization, in which a large amount of chalcopyrite and cobalt pyrite were formed. the co content of cobalt pyrite can be over 1% and its co/ni ratio over 26. it is suggested that the process of cu-co enrichment in the deposit is closely related to the latter stage of volcanic activity, this deposit could be recognized as a volcanic exhalative sedimentary iron deposit, and its ore-forming temperature ranges from 270 degrees c to 325 degrees c. |
