Application of the Euler deconvolution 2D and 3D at the Pari syncline, internal area of the Paraguay Belt, Mato Grosso, Brazil

Abstract

Among the several techniques that allow the estimation of mean depths from airborne geophysical magnetic data, the Euler deconvolution became popular due to the high level of reliability in the generated data. With the use of this tool, it is possible to study structures remotely at different crustal levels that may or may not contain mineralization, consequently being able to determine potential targets for mineral exploration or to study better its relation with the structural background. With the analysis of the magnetic susceptibility of subsurface and the inversion profiles of the magnetic data (Euler deconvolution 2D) were interpolate a 3D model of the region, that allowed to generate a descriptive suggestion of the geometry of the Pari syncline, located in the Cuiabá Group, in the northwestern portion of the Paraguay belt. It has a strong structural control in the context of the Pari River basin and a great auriferous potential, as evidenced by updated research and exploration data. The data applied in this paper were extract from the Cuiabá aerogeophysical project and previous mappings and have their mean depths correlated with the Cuiabá group.
