The identification of fractures is of great importance in gravity and magnetic data processing and in- terpretation. In this study,four fracture identification methods are applied,and widely used in processing and analysis of the gravity anomaly,including vertical second derivative method,tilt derivative method,theta map method and normalized differential method, for gravity data acquired in a given area in Heilongjiang. By compa- ring the distribution of the zero contour or maximum contour,we summarize the application effects,and both advantages and disadvantages of each method. It is found that tilt derivative method and normalized differential method provide better effects than other two methods: the narrower anomaly gradient belt and higher identifica- tion precision of fracture or geological boundary. The inferred fractures and geological boundaries have a great match with the results obtained from geologic map and remote sensing data interpretation. Those study results have definitely provided the theoretical foundation for identifying faults and the geological boundaries.
