Abstract: Qimantage region is an important part of northern Tibetan Plateau,it is located in the structural knot of Altyn,East Kunlun,Qadam block,and it is the main source of mineral resources in the western part of East Kunlun.Taking Xiarihamu Cu-Ni deposit in Qimantage region as the study area,based on the integrated information prediction theory and the integrated geological prospecting information obtained by geophysical,geochemical and remote sensing techniques,the regional metallogenic geological conditions and metallogenic regularities are studied,the metallogenic prediction model of Ni deposit is established,besides that,the Ni resources prospecting potential evaluation system is established by using the mineral resources assessment system (MARS) of GIS software.Based on the above discussion results,11 metallogenic prediction areas of intrusive magmatic Ni deposit are delineated by adopting integrated information method of geological unit of deposit integrated model,they are composed by 1 A-type metallogenic prediction area,2 B-type metallogenic prediction areas and 8 C-type metallogenic prediction areas,and the Ni resources reserves is predicted by using geological volume method.The study results show that,Ni resource reserves within the depth of 500 m is 3 056 658.39 t,Ni resource reserves within the depth of 1 000 m is 611 126.77 t,the total resource reserves of the metallogenic predictions areas delineated in this paper is 3 667 785.16 t,which show that the prospecting potential of Ni deposit in Qimantage region is huge.The above study results related to the Ni deposit in Qimantage region can provide some reference for conducting further prospecting and exploration work in the area.Ni deposit,Geological prospecting information,
