The Zhunsujihua porphyry molybdenum deposit of Inner Mongolia is a medium sized metal deposits.Currently there is no deep drill hole data within the exploration area.In this study, high-precision seismic reflection measurement was conducted for detecting the deep metal deposits, ore-controlling structure and deep geological structure in the molybdenum ore district and its periphery.The reflection seismic method of 2 sets of high power vibrator for stimulation, 5 m group interval, 960 receiving and 80 folds were used, and high-precision seismic reflection profiles which can reflect clearly deep geological structure was obtained.Ore-passage structure and ore-controlling structure, concealed rock mass distribution as well as cross-cutting relationships of rock masses of Variscan and Yanshan period can be clearly explained on the section.The deep crustal fluid migration paths and dynamic process are discussed.The prospecting target zone is delineated in search for concealed metal ore deposits in the area.
