WebABSTRACT Three-dimensional gravity inversion has been widely used to infer density structures and tectonic movements of the earth and Moon. However, two problems (the nonuniqueness and low depth resolution) of current gravity inversion methods still exist and are not completely resolved, which affect the reliability of the inversion results and the … Webrepresents the components of a traceless, symmetric tensor with 5 independent components. Tij has been decomposed into three objects that transform like the spherical harmonics with l = 0, 1, and 2 respectively. It has been decomposed into irreducible spherical tensors.
