Through analyzing 1:50 000 aeromagnetic anomalies and other geophysical characteristics, the authors got to know that the Xiarihamu copper-nickel deposit shows weak magnetic anomaly in the aeromagnetic anomaly map, and shows medium strong magnetic anomaly in the geomagnetic anomaly map.The basic-ultrabasic complex has moderate magnetism, whereas pentlandite, pyrrhotite and some other minerals have strong magnetism which is in the main residual magnetism.Copper-nickel ore is the main factor causing the magnetic anomaly, and the magnetic anomaly is a direct prospecting mark in search for such deposits.Aeromagnetic anomaly has important significance in search for magmatic liquation copper-nickel deposits.There are many aeromagnetic anomalies in Eastern Kunlun area, suggesting that this area has the potential to find magmatic liquation copper-nickel deposits.
