Abstract

Final model of one-dimensional magnetotelluric inversion should be consistent with geology of the region. In most sharp 1D inversion, final model is not consistent with the geology especially in the last layer. Smooth inversion such as Occam’s method often are very smooth that the thin layers are masked or difficult to model. There is uncertainty in the Larsen’s algorithm (1981), such as sharp algorithms especially the last layers. So Larsen used kernel function to overcome this problem. In the present method, the Larsen’s algorithm has been used while there are multiple layers, usually more than 10. In our method, solving kernel functions are not necessary and the depth scale is selected automatically. Finally, the method has been performed on some artificial and real data successfully.
