Resistivity and magnetic profiles of TEO-4. Resistivity was measured using a Wenner array. Dashed line: total electric anomaly, square plus line: residual electrical anomaly, continuous line: magnetic profile. The zone of interest is marked with a box. The magnetic anomaly shows a maximum correlated with another maximum in the electrical anomaly, that reveals the presence of a basaltic mass (confirmed by a test core).
