| 中文摘要: |
| 灶火河西铁多金属矿位于东昆仑中岩浆弧带与祁漫塔格结合带上,该矿床是近些年新发现的一处铁多金属矿,矿体主要赋存于花岗闪长岩与碳酸盐岩的外接触带上,少部分产出于岩体与围岩的内接触带中以及破碎蚀变带中,含矿围岩为古元古界金水口岩群,矿体多呈不规则条带状、透镜状,近北西西展布,受接触带控制明显,少部分矿体受断裂及层间破碎带控制明显,矿石矿物主要为磁铁矿、钛铁矿、黄铁矿、黄铜矿、硫砷铜矿等。笔者通过对灶火河西铁多金属矿成矿特征、矿床成因及物化探资料研究,认为成矿及接触带及断裂构造关系密切,矿床成因类型主要为夕卡岩型或接触交代型,该区具有较好的找矿前景。 |
| 英文摘要: |
| The western Zaohuohe iron polymetallic deposit, newly discovered in recent years, is located in the eastern Kunlun magmatic arc belt and jointed part with the Qimantage tectonic belt. The iron orebody mainly occurs in outlier contact zone between granite diorite rock and carbonate rock, minor iron orebodies occur within inner contact zone and fractured alteration zone. The host rock is Proterozoic Jinshuikou group formation. The ore bodies mainly distributed in forms of irregular banded and lensed strike along North-West, which are controlled by the contact zone significantly, minor is controlled by faults and interlayer fracture zone.The ore minerals are mainly magnetite, ilmenite,pyrite, chalcopyrite and enargite. Based on integrated analysis of metallogenic characteristics,deposit geneses,geophysical and geochemical data, it was concluded that the mineralization is closely related to the contact zone and fractures, the deposit genesis is mainly skarn type or contact metasomatic zone type, thus there is great prospecting potential for skarn type deposit in the area. |
