Abstract In fine precision magnetic survey data processing and interpretation usually requires quantitative interpretation of the magnetic body depth information for the study of regional tectonic,magmatic rocks and ore analysis also has important significance.Power spectrum method is a common method for calculating the depth of the magnetic material but the program uses the sliding window method.And parameter selection subjectivity can cause a calculation error.The author through computer interaction 2.5D gravity and magnetic joint inversion fitting and drilling data comparative analysis,select the optimal parameter combination,uses the power spectrum method to calculate the depth information of magnetic substance in Yin-E basin Juyanhai depression.
