This paper deals with methods and properties of Tilt-Euler deconvolution by analyzing the theoretical model and the measured gravity data. The results show that the Tilt-Euler deconvolution method can rapidly provide automatic estimation of the source location and source type from gridded gravity or magnetic data on condition that no structural index is required, and can also automatically estimate the structural index. With simple calculation and high practical use, this method is of great significance in large-area aeromagnetic and airborne gravity data processing and interpretation.
