             abstract = "This paper describes the combined use of gasometric data, 
                         terrestrial radiometric data, reflectance spectroscopy data and 
                         ProSpecTIR-VS hyperspectral imagery to characterize soils and 
                         vegetation anomalies due to the presence of natural seepages in 
                         the S{\~a}o Francisco Basin, a region known as Remanso do Fogo. 
                         The locations of seeps were mapped using image processing 
                         techniques and the results demonstrated that the absorption bands 
                         of kaolinite and iron oxides/hydroxides can be used for that 
                         purpose with some limitations. Although hydrocarbon anomalies 
                         increase the content of kaolinite and decrease the content of iron 
                         oxides, drainage systems and the relief can mobilize minerals in 
                         soils, thus encumbering their correlation with gas seeps. In such 
                         situations vegetation anomalies as well as gamma ray anomalies 
                         (Higher DRAD and Ures, lower Kres) may be used as determinative 
                         vectors of the existence of seeps. The combined use of 
                         multi-source data in the characterization of soils and vegetation 
                         submitted to natural gas seeps in the region of Remanso do Fogo 
                         provided a better comprehension of changes induced in soils and in 
                         vegetation by the presence of gases in soils, based on a greater 
                         detailing of spectral features of interest.",
