| Summary | As a low-cost deep exploration technology, the magnetotelluric (MT) method has been widely used in the detection of deep electrical structures for studying geoscientific problems. With the expansion of the detection range and the requirement of high resolution, the conventional MT three-dimensional (3D) inversion methods face challenges. First, the electrically anisotropy caused by mantle inhomogeneity cannot be mimicked by isotropic models, and there don’t exist mature methods for 3D MT anisotropic inversion. Second, the increase in research scale expands the spatial dimension of the inversion model, enhances the under-determination of inversion, and affects both convergence and stability. To solve these problems, we propose a 3D MT inversion method based on equivalent transformation. Through numerical experiments and measured data inversion, we prove that our new method can improve the stability and convergence efficiency of 3D MT anisotropic inversions. |
