Levantamiento de datos gravimétricos en las formaciones sedimentarias de la cuenca Malacatos

Abstract

Abstract: The present research work refers to the study of the northern area of the Malacatos sedimentary basin from a Geological - Structural and Gravimetric field survey through relative measurement stations placed along two profiles in a Northeast-Southwest arrangement . For this investigation, 68 gravimetric measurement stations were available with a separation of approximately 250 meters. By collecting the data obtained in the field and subsequent processing, it was possible to determine the geometry and depth of the sedimentary fill on the metamorphic basement, allowing negative Bouguer anomaly values to be obtained, represented in an anomaly map. The gravimetric models were obtained from residual anomaly data, calculated with the Bouguer anomaly data and subsequently correlated with geological and structural data of the area, obtaining information on the depth of the sedimentary fill as well as the great variety of geological structures that characterize this area.
