Estudio gravimétrico de la transversal central de la cordillera de los Andes, con fines de evaluación tectónica y profundidad cortical del basamento. Tramo Manta-Quevedo-La Maná, cuenca de Manabí.

Abstract

The present research concerns about the collection of gravimetric data at 1 °S of latitude, oriented from West to East that crosses of the Manabí basin between “El Tingo” which belongs to Pujilí canton in the province of Cotopaxi to the city of Manta in the province of Manabí. The data 225 gravimetric measurement stations were placed at a distance of approximately 1 kilometer.

The processing and correction of gravimetric data generates positive and negative values of Bouguer anomaly throughout the study area, which allow generating residual anomalies and from the variation of density in different types of rocks a gravimetric model can be made.

With the collected fieldwork information and the obtained gravimetric model, in addition to information from previous studies of the area, it is possible to generate a geological profile, that allows analyzing the tectonic model of the region based on deep structures of the main regional faults of the zone.
