Inversion of resistivity soundings in the archaeological site of Mahilaka (North-West of Madagascar) using the generalized linear inverse method

This paper describes the generalized inverse method which is used for the inversion of resistivity sounding. The technique has been applied to a resistivity soundings survey whose stations are selected in the zones of resistivity anomalies over an archaeological site. The site covers an area of 0.75 square kilometer in the north-western part of Madagascar, bordering the east Mozambic Channel. The one-dimensional (1-D) model fits well the observed data and the generalized linear inverse method appears to be a powerful scheme with which to interpret resistivity sounding data.
