Abstract

The San Juan Londó ground water basin is located north of La Paz, Baja California. A ground magnetic survey was carried out to define the geometry and structural boundaries of the basin. A total of 173 magnetic stations were measured and corrected for diurnal variation and for the geomagnetic field. The data were interpolated on an equally spaced grid of 256 km2. A Fourier analysis was applied to perform a regional- residual separation by designing suitable high and low pass filters, combined with a reduction to the pole of the magnetic data to center the anomalies over the bodies. Interpretation suggests that the valley is divided in three main sub-basins separated by a horst-like formation.
