China developed the aeromagnetic three-component measurement system in 2017; nevertheless, the application of the three-component data is still in the exploratory stage. At first, the authors derived the upward continuation formula of magnetic three-component data and obtained the formula for the first time. Then the authors designed cube combinational models, with depth of center point ,volume, magnetization in different depths and depth of top surface as the variables. The relationship between minimum continuation height and physical parameters was obtained. In addition, the authors summarized some laws from these models. Finally, these conclusions were combined with the actual aeromagnetic three-component data. According to the geological condition of the survey area, the interpretation was made and good results were obtained.
