Based on a 2-D discrete wavelet multi-resolution analysis for gravity anomalies in Eastern Tarim Basin and Tianshan orogenic belt,this paper presents a calculation of the waveleng the wavelength range and the depth of sources for different level details and approximation of Bouger gravity anomalies.

The distribution pattern of Bouguer gravity anomalies in Hefei basin has been described in detail,and the 1st order to the 4th order wavelet details were calculated.

This paper researches and developes a gravity anomalies data processing system.

Using high-resolution filtering method of gravity-magnetic anomalous apparent-velocity for implementing apparent velocities filtering processing of Bouguer gravitational anomaly in Dongying depression, the horizontal slices from the shallow to the deep are acquired.

The algorithms are applied in the gravitation-anomaly measuring system to alleviate the effect of gravitational anomaly on the high-precision gravitation measurement.

Conducting forward calculation of gravitational anomaly according to crastal depth measurement data, crastal thickness of the ragion has bee.
