LOPEZ-LOERA, Héctor  y  TRISTAN-GONZALEZ, Margarito. Geology and magnetometry of the Villa de Reyes graben, San Luis Potosí, Mesa Central, Mexico: tectonic implications. Bol. Soc. Geol. Mex [online]. 2013, vol.65, n.1, pp.137-156. ISSN 1405-3322.

The study is focused on learning about the underground geology and tectonics in the Villa de Reyes Graben. The aeromagnetic data is processed through a series of mathematical filters that allow us to increase the resolution of weak anomalies in some cases or, in others, to simplify the appearence of magnetic maps by suppressing local features in order to observe and analyze surface or deep geological structures. The study allowed us to identify fault and/or fractures zones that are under alluvial cover, and to identify sources of volcanic activity beneath the existing volcanic deposits on the shoulders of the Villa de Reyes Graben. The interpreted aeromagnetic trends allowed us to identify the aquifer recharge zone in the area.

Palabras llave : Villa de Reyes Graben; aeromagnetometry; geology; fault and/or fractures; magnetic trends.
