Preliminary study of gravimetric anomalies in the Magallanes-Fagnano fault system, South America

The main objective of this research is to recognize several geological structures associated with the shear zones of the MFFS (Magallanes - Fagnano fault system) by the analysis and interpretation of gravimetric anomalies. Besides, to compare the gravimetrical response of the cortical blocks that integrate the region under study, which is related to the different morphotectonic domains recognized in the region. This research was developed employing data obtained from World Gravity 1.0, which includes earth and satellite gravity data derived from the EGM2008 model. The study and interpretation of the MFFS from the analysis and processing of the gravimetric data, allowed appreciation of a noticeable correlation with the most superficial cortical structure.
