Reassessment of the volume of the Las Aguilas mafic-ultramafic intrusives, San Luis, Argentina, based on an alternative geophysical model

► Recalculates the volume of the mafic-ultramafic intrusion ► Proposes an alternative model to the big gravimetric anomaly in the Sierra de San Luis ► Calculates the thermal effect in the host rock due to the intrusion of the mafic-ultramafic bodies ► Discusses the cause of the anomalous heat in the Pringles Metamorphic Complex.
