Abstract (summary)
Analyses of electron paramagnetic resonance (EPR), in order to determine the organic matter free radical concentration (OMFRC), and magnetic susceptibility (MS) measurements were carried out in soil (surface and depth (≈ 1-2 meters)) samples from a prospective area located at the southern flank of the Andean Range in Venezuela. The results indicate the presence of anomalous zones in this area. These anomalous values could be the result of the reducing environment induced by the hydrocarbon gas leakage. Results for demineralized samples allowed discussing differences between surface and depth ones in terms of weathering effects and change in organic matter type.
