Caracterização Das Falhas do Rifte da Bacia Potiguar (Rn) Através da Utilização de Deconvolução de Euler 3D

The Euler deconvolution is an automatic method of inter-pretation that can provide an accurate estimate of hori-zontal position and depth to anomalous sources from potential field data. In this work we show the use of Euler deconvolution of gravity data to characterize the rift struc-tures of the Potiguar Basin (RN State) using as the main parameter the structural index an exponential factor cor-responding to the decay rate of the potential field with the distance between the source and the measurement point, an indicator of the geometric form of the anomalous source. The best results were obtained with a structural index equal to zero, which represents faults, a spatial window size equal to 20 km, which is used to determine the area that should be used for the calculation of Euler deconvolution, and maximum tolerance of error ranging from 0 to 7%, that determines which solutions are accept-able, thereby obtaining a cloud of Euler solutions that allowed us to characterize the main limits of the Potiguar Rift, well as their depth and dip intensity.
