哈西亚图铁多金属矿床成矿条件研究

Research of Metallogenic Conditions of Haxituya Iron Polymetallic Deposits in Qinghai Province

通过对哈西亚图铁多金属矿地质背景、成矿条件等研究,发现哈西亚图铁多金属矿床属层状矽卡岩型矿床;其成矿物质不仅在空间上具有明显的分带性,在成矿期上也具有铁、锌先期富集、金及锌后期叠加富集的特点;磁铁矿成矿物质来源主要为矿区北部的石英闪长岩体,后期岩浆作用对矿化形成叠加富集。哈西亚图铁多金属矿的发现,显示了祁漫塔格地区金水口岩群内具备较好的铁多金属矿及金矿找矿潜力。

According to the study of the geologic background and metallogenic conditions of Hax-ituya iron-polymetallic deposit , it was found that the type of Haxituya iron -polymetallic deposit is the layered skarn .The metallogenic materials is zonation not only in space , but also in minerali-zation period with Fe-Zn primitive enriched and later Au -Zn superimposed enrichment .The met-allogenic materials of magnetite mainly refer to quartz diorite body in the north of the mining area , later magma mineralized to be superimposed enrichment .The discovery of iron -polymetallic de-posit in Haxituya indicates good prospecting potential of iron -polymetallic and gold deposits in Qi-mantage district .
