LOPEZ-LOERA, Héctor. Geophysics for groundwater location in arid volcanic environments in the Mesa Central: The La Dulcita case, Villa de Ramos, San Luis Potosí, Mexico. Bol. Soc. Geol. Mex [online]. 2014, vol.66, n.1, pp.165-181. ISSN 1405-3322.

One of the most important problems in arid zones is the one related to the exploration and exploitation of groundwater. This paper presents the air and ground magnetic method as a tool for locating zones associated with permeability (fracturing), by means of the interpretation of alignments and of air and ground domains. Based on these interpretations, electrical methods by sections and vertical electrical soundings are used to verify if the zones are correlated to the moisture underground. If both permeability and moisture are met, they are considered as zones with high probability of locating groundwater in the Mexican Central Mesa arid zones. The application of this methodology is presented in a rural population in the State of San Luis Potosí, where problems with the location of these resources exist.
