| Abstract: | Mohr circle analysis is a qualitative method for interpretation of magnetotelluric (MT) data. It uses various rotational invariants of impedance tensors and their composite as its basic parameters, so as to visually and clearly displays the features, such as dimensions, 2D deviation degree, anisotropy, strike orientation, and impedance of the main axis of electrical structures. The conspicuous feature of the method is that it can be used for determining the dimensions of structures. For 1D structure, the M... |
