Determining the locations and the dipping angles of the faults is one of the most important issues in the interpretation of the gravity profile data.The authors first construct a series of 2D fault models with different geometric parameters (e.g., locations and dipping angles).Then the theoretical gravity responses of the models are applied to the correlation scanning with the observing gravity profile data in the moving windows.According to the comparison between the calculated correlation values and the threshold value,we can judge whether the faults exist or not beneath the centers of the windows.If the faults exist,the corresponding geometric parameters of the maximum correlation value are treated as the interpretation results.The synthetic model tests suggest that it is effective to identify the faults with different dipping angles.Moreover,the correlation scanning method is applied to an actual profile of the gravity data in field,and the results show that the determined locations and dipping angles of the faults by the proposed method are consistent well with those of the known faults detected by surface geological survey and other geophysical probes.Therefore,both the synthetic tests and the field example indicate the validity of the method presented in this paper.
