A Novel Approach to Edge Detection for a Gravity Anomaly Based on Fractal Surface Variance Statistics of Fractal Geometry

Fractal geometry has developed rapidly, and is widely used in various disciplines. However, only a few fractal dimension methods techniques have been applied to the processing of gravity data, especially detection geological edges interfaces. In this paper, definition, properties characteristics dimensions are improve edge anomalies, theoretical model established. At same time, new method surface variance statistics compared with traditional methods. The anomaly different directions analyzed, results show that maximum value statistical on fixed window can be delineate ore body. When paper Luobusha chromite deposit Tibet, China, corresponds well structural development zones faults, it also helpful boundary identify interface an obvious difference density.
