BUSTAMANTE-OROZCO, Marco Rogelio; MEDRANO-PEREZ, Ojilve Ramón; NERI-FLORES, Iris  e  ANGELES-CORDERO, Edgar. Interpretation of aeromagnetic and gravimetric satellite data to identify areas with aquifer potential in the western Grijalva basin, Mexico. Bol. Soc. Geol. Mex [online]. 2023, vol.75, n.1, e031122.  Epub 25-Maio-2024. ISSN 1405-3322.  https://doi.org/10.18268/bsgm2023v75n1a031122.

The goal of this research is to interpret the magnetic and gravimetric responses subsurface in the western portion of the Grijalva basin, Mexico, in order to identify and delimit the areas of rock units with aquifer potential. For it, the processing of satellite aeromagnetic and gravimetric data was carried out with the purpose of delimiting the geological characteristics of greatest interest. The results show that the north-central part of the study portion represents the area with the greatest aquifer potential, and it coincides with the areas of greater sedimentary thickness, of lower altitude, and where the groundwater concessions are concentrated. Therefore, the change of gradients between magnetic and gravimetric responses contributes to the knowledge of the structural framework (faults, fractures, edges, and geological contacts) and the inference of areas with aquifer potential. In detail, from the filters used, the Tilt Derivative (TDR) presents the linear trends associated with the structural framework of a specific water interest. It seeks to promote decision-making and research on geohydrological topics, territorial planning, and related public policies.
