Abstract:
Based on the iron deposits in Altay of Xinjiang, the metallogenic setting of iron deposits were reviewed, the genetic types and mineralization period of iron deposits were divided, geological characteristics of typical deposits were described, the temperature and salinity of ore-forming fluid and its source were analyzed, and the tectonic evolution and metallogenesis were discussed. The results showed that the genetic types of iron deposits were dominantly volcanic rock, skarn, pegmatite, hydrothermal related with granite, V-Ti-magnetite related with basic massif and placer; homogenization temperatures of fluid inclusion in skarn type deposit from skarn to retrograde alteration until quartz-sulfide-carbonate stages gradually decreased from 200 ℃-500 ℃ to 200 ℃-350 ℃ until 160 ℃-300 ℃, and the peak of fluid salinities(NaCleq)also decreased from 4.5%-21.5% to 3.5%-20.5% until 1.5%-17.5%, respectively; ore-forming fluids in the sedimentation period of Tuomoerte iron(manganese)deposit were characterized by low-medium temperature(mainly 160 ℃-300 ℃)and low salinity(mainly 4%-9% and 14%-20%); ore-forming fluids in Liangkeshu iron deposit with pegmatite type were characterized by medium temperature(173 ℃-290 ℃)and low salinity(0.35%-16.05%). Hydrogen and oxygen isotope compositions suggested that the ore-forming fluids in the sedimentation period of iron deposit with volcanic sedimentary type were mainly derived from the mixture of seawater and magmatic fluid; the ore-forming fluids in skarn and quartz-sulfide-carbonate stages were mainly derived from magmatic fluid and atmospheric precipitation mixed with a little of magmatic fluid, respectively; the ore-forming fluids in Liangkeshu iron deposit with pegmatite type were mainly derived from the mixture of magmatic fluid and atmospheric precipitation. Carbon and oxygen isotope compositions suggested that the carbon in the ore-forming fluids of iron deposits with skarn type was mainly derived from deep magmatic, and a little from marine carbonate rocks.
