Abstract: The porphyry copper-molybdenum deposit is the main source of copper and molybdenum and the main direction of geological prospecting due to its characteristics of large scale，shallow bury and easy exploitation.So，it has great significance to investigate the prospecting method of porphyry copper-molybdenum deposit.Taking the Luming molybdenum deposit（the typical porphyry deposit for which the detailed survey and exploration work have been done) as the research object，various geophysical exploration methods including gravity and magnetic anomaly，induced polarization，high density resistivity and controlled source audio-frequency magnetotelluric(CSAMT)are adopted to systematically analyze the geophysical anomaly characteristics of the mining area，combining with the ore deposit geology characteristics of parts of the ore-body.The geological and geophysical model of mining area is established，and the geophysical exploration methods and implementation steps for seeking for this type of ore deposit are summarized.The above research results can provide some references for the prospecting work in the mining area and the similar areas.

Key words: Porphyry molybdenum deposit, Geophysical characteristics, Geological characteristics of deposit, Characteristics of geophysical anomalies, Geological and geophysical model
