Abstract: Zharigen iron deposit is located in the Sanjiang metallogenic belt Tuotuohe segment,which is located in the side of Qiangtang landmass between the lated Indo-Chinese epoch Bayanhar folding-orogenic belt and Qiangtang landmass the two major tectonic units.Mine claim is an east-west axis,and an incomplete anticline form,exposed Permian strata Kaixinling groups Nuoribagaribao group.Exist-ore country rock is Indo-Chinese epoch mafic subvolcanic rocks,the east section of the exist-ore rocks located in anticlinal axis and south-limb,the central and western sections of the mine lie in the anticline north wing rocks.Ore body has been controlled by subvolcanic rocks and its internal early tectonic fissures,and genesis of this ore deposit belongs to subvolcanic magmatic hydrothermal type.Structure position of the host rock is conducive to forming large-scale magnetite bed.Using magnetic method to find magnetite is perferable in this area.However,the current mining area parts of 1:2000 magnetic anomaly are not checked or lack of deep drilling engineering project,and the depth control is not enough.It will be expanded resource perspective,if increase further verification efforts.In southern of ore area magnetic anomaly is not yet traps,expanding the range of high-precision magnetic survey in order to find new anomaly,and then determine the inversion of magnetic anomalies in distribution and spatial form,locking the advantageous parts of the ore and drilling enabling authentication,expecting to found large-scale magnetite body in the deep.
