Acesso em:.http://bdm.ufpa.br/jspui/handle/prefix/896Applying 1D inversion to 2D magnetotelluric data allows the geophysicist to obtain fast and meaningful results, despite the inherent limitation of trying to approximate the subsurface response by models that vary only in one direction. This paper presents a way to minimize this limitation by performing the inversion of a set of MT soundings with constraints that take into account the lateral variations in the resistivity of the subsurface. The data from all sounding stations in an MT survey line are inverted jointly, producing layered columns with lateral smooth transitions. This process takes advantage of the low computational cost of 1D inversions, and it generates an approximate 2D model that can be useful as a first guess in a full 2D inversion. Two synthetic examples are used to evaluate the practical utility of the algorithm.Acesso AbertoProspecção - Métodos geofísicosProspecção magnetotelúricaGeofísicaCNPQ::CIENCIAS EXATAS E DA TERRA::GEOCIENCIAS::GEOFISICATrabalho de Curso - Graduação - Monografia
