Erzincan Basin was investigated using gravity data within the scope of this study. It is also aimed to reveal the discontinuities in the work area as well as the buried discontinuities. Boundary determination filters and analysis of the structure of the data and its connection are revealed and clear information is obtained. Gravity anomalies were applied with an upward continuation method for 0.25, 0.50, 0.75 and 1 km levels. Total Horizontal Derivative (THD) filter, Analytical Signal (AS) filter, Tilt Angle Derivative (Tilt) filter, Total Horizontal Derivative (THDR) filter, Theta Angle Derivative (Cos ɵ) filter, Hyperbolic Tilt Angle Derivative (HTAD) were applied to upward continued data. The discontinuities in the region and the boundaries of the geological structure were revealed. Tilt and Theta Angle derivatives yield the best results from the applied derivative based filters. The obtained data were compared with the existing surface geology and the compatibility between the formations was checked. New discontinuities were found in addition to the discontinuities determined from surface observations in the light of the obtained results. Erzincan Basin was modeled in three dimensions using gravity data of the study area. As a result of modeling, Erzincan Basin has been determined to have an average thickness of 7 km.

El objeto de este estudio fue investigar la cuenca Erzincan a través de información gravitacional. También está enfocado en revelar las discontinuidades en el área de estudio asi como las discontinuidades enterradas. Se exponen los filtros de determinación de límites y los análisis de la estructura de la información para obtener información clara. El método de continuación hacia arriba se aplicó en las anomalías gravitacionales en niveles de 0.25, 0.50, 0.75 y 1 km. A la información continuada hacia arriba se le aplicaron los filtros Total Horizontal de Derivadas (THD), Señal Analítica (AS), Ángulo Inclinado de Derivadas (Tilt), Ángulo Theta de Derivadas (Cos ɵ), y Ángulo Inclinado Hiperbólico de Derivadas (HTAD). Este proceso permitió revelar las discontinuidades en la región y los límites de la estructura geológica. Las derivadas de Ángulo Inclinado y Ángulo Theta produjeron los mejores resultados en cuanto a las derivadas aplicadas con base en filtros. La información obtenida se comparó con estudios de superficie geológica y se revisó la compatibilidad entre las formaciones. Se encontraron nuevas discontinuidades adicionales a las discontinuidades determinadas en las observaciones de superficie a la luz de los resultados obtenidos. La cuenca Erzincan se modeló en tres dimensiones con información gravitacional en el área de estudio. Como resultado de la modelación, se determinó que la cuenca Erzincan tiene un promedio de profundidad de 7 kms.
