Multifractal singular spectrum analysis model and application
多维分形奇异功率谱分析与应用

The singularity of a geophysical or geochemical data reflects their spatial self-similar or self-affine property.It is useful in data estimation(interpolation),mineral exploration,and environment assessment.The current singularity estimation algorithm assumes the data is isotropic in the vicinity of every location.However,geophysical or geochemical data is often anisotropic,and it is often happened that the most hopeful target in mineral exploration locates at the sub-tectonic structures,where anisotropy occurs,inside the major tectonics.The new anisotropy singularity estimation method is implemented in a GIS environment in this study to use the strong spatial analysis power of GIS.The Bouguer anomaly of the southern Nova Scotia,Canada,is used to demonstrate the anisotropy parameters estimation for mineral potential mapping.The results demonstrated that the given anisotropy singularity method is a power tool in mineral potential assessment.
