and the base level for a given nature (i.e., structural index

– SI) of a geologic source based on the magnetic dada.

These estimates are computed inside a moving data

window spanning the whole dataset. The selection of the

best estimates is related to the plot of these estimates.

Traditionally, for each SI, the estimates of source

horizontal coordinates obtained for each position of a

moving data window are plotted in the plan view of the

study area and the estimates of source depth are

represented by different color or size. This traditional plot

requires a criterion to select the best estimates and deal

with the spread of solutions. In this case, mostly, the baselevel

estimates are computed but they are not used or

shown. We compare the traditional plot of the estimates

from magnetic fields with an alternative plot where, for

each SI, every estimate is plotted against the central

position of the moving data window. At this plot, when the

correct SI is used the solutions form a plateau of constant

values. We perform the analysis for synthetic data sets

generated by different SI and for a real data set, beyond

that; we plot base-level estimates in the traditional way. We

run Euler deconvolution over the Diorama anomaly,

located in the Goiás Alkaline Province, Brazil, and analyze

the estimates over different plots. From the results of both

plots we may infer that Diorama anomaly is generated by

at least two vertical plugs.
