Visualization of Euler deconvolution estimates on traditional and plateau plots

<div>of potential field data. The method estimates the position</div><div>and the base level for a given nature (i.e., structural index</div><div>– SI) of a geologic source based on the magnetic dada.</div><div>These estimates are computed inside a moving data</div><div>window spanning the whole dataset. The selection of the</div><div>best estimates is related to the plot of these estimates.</div><div>Traditionally, for each SI, the estimates of source</div><div>horizontal coordinates obtained for each position of a</div><div>moving data window are plotted in the plan view of the</div><div>study area and the estimates of source depth are</div><div>represented by different color or size. This traditional plot</div><div>requires a criterion to select the best estimates and deal</div><div>with the spread of solutions. In this case, mostly, the baselevel</div><div>estimates are computed but they are not used or</div><div>shown. We compare the traditional plot of the estimates</div><div>from magnetic fields with an alternative plot where, for</div><div>each SI, every estimate is plotted against the central</div><div>position of the moving data window. At this plot, when the</div><div>correct SI is used the solutions form a plateau of constant</div><div>values. We perform the analysis for synthetic data sets</div><div>generated by different SI and for a real data set, beyond</div><div>that; we plot base-level estimates in the traditional way. We</div><div>run Euler deconvolution over the Diorama anomaly,</div><div>located in the Goiás Alkaline Province, Brazil, and analyze</div><div>the estimates over different plots. From the results of both</div><div>plots we may infer that Diorama anomaly is generated by</div><div>at least two vertical plugs.</div>
