Estudios geofísicos aplicados a la tectónica de la falla Solanda en la parroquia de Quinara

Abstract

Abstract: The present study allowed an evaluation of the Solanda fault, through direct and indirect methods. Three geophysical profiles of microgravimetry and electrical resistivity tomography were performed to establish correlations based on geological data collected in the field. The data obtained from microgravimetry, defined values of the Bouguer anomaly of -187 to -200 mGal and residual minimums that define the depth of the basement rocks. Based on the 2D model of microgravimetry, the thickness of the sedimentary rocks and the change in jumps of the anomaly that indicate the existence of inferred faults were defined. With electrical resistivity tomography, conductive and resistive values were determined that correlate with lithological changes and the presence of fault zones due to low resistivity where areas may have conductive materials due to the presence of fractured areas. With the data obtained from the field and indirect methods, the lithological changes and the presence of fault zones were correlated and interpreted in a structural geological model for the Quinara area.
