The Goulfey-Tourba sedimentary basin (GTSB) is a portion of the West and Central African Rift System whose studies on its structural geology remain very limited. Belonging to the vast semi-arid Sahelian region, this sedimentary basin covers several localities in Cameroon and Chad, whose economic and social activities are highly impacted by the shortage of drinking water. In this work, a new look is taken at the geological features of this local sedimentary region. To perform this, a preliminary synthetic study is carried out to assess the performance of some classic and recent edge detection methods. The effectiveness of the recent Improved Logistic (IL) method is approved, given its ability to highlight low amplitude and deep features with a refined resolution. A regional/residual separation was applied to Bouguer gravity disturbances to avoid blurring some upper crustal structures by high-frequency anomalies. The effectiveness of this regional/residual separation has been validated by checking the absence of ringing artifacts (Gibbs phenomenon). The application of the IL method on residual gravimetric disturbances of the study area revealed a series of lineaments not yet identified by previous scientific studies. The results show a slight fracturing of the basement, with geological features mainly trending in an NW-SE direction. A newly identified geological discontinuity continuously crosses the study area from 12o45'N latitude to the southeast. Utilizing a modified and recent form of the Euler deconvolution theory (Improved Tilt-Euler method) has enabled the detection of several density sources in the GTSB, most of which correlate well with the lineaments outlined by the IL method. The improved Tilt-Euler method results show anomalous sources at more than 6 km depth beneath the Bodélé sedimentary series of the Upper Tertiary. The Euler’s linear solutions attributed to basement fractures show an average depth of 1 km. These results are undoubtedly a major contribution to refining the research of hydrogeological resources in this Sahelian area.

La cuenca sedimentaria de Goulfey-Tourba se encuentra en el sistema de rift de África Central y Occidental, pero sus estudios de geología estructural son muy limitados a la fecha. Perteneciente a la vasta región semiárida del Sahel, esta cuenca sedimentaria cubre varias localidades en Camerún y Chad, cuyas actividades económicas y sociales se ven fuertemente impactadas por la escasez de agua potable. En este trabajo se ofrece una nueva mirada a las características geológicas de esta región sedimentaria. Para el cumplimiento de este objetivo se realizó un estudio sintético preliminar con el fin de medir el desempeño de algunos métodos clásicos y recientes de detección de bordes. Se aprobó la efectividad del reciente método de Logística Mejorada debido a su capacidad para resaltar las amplitudes bajas y las características profundas con una solución fina. Luego se aplicó una separación regional/residual a las anomalías gravitatorias de Bouguer para evitar el desenfoque de algunas estructuras de la corteza superior por las anomalías de alta frecuencia. La efectividad de esta separación regional/residual se ha validado al verificar la ausencia de discontinuidades (fenómeno de Gibbs). La aplicación del método de Logística Mejorada en las anomalías gravimétricas residuales en el área de estudio reveló una serie de lineamientos que no habían sido identificados. Los resultados muestran un fracturamiento ligero en los cimientos, con características geológicas con una tendencia mayoritaria en la dirección NW-SE. Una recién descubierta discontinuidad geológica cruza regularmente el área de estudio desde la latitud 12o45'N hacia el sudeste. Al utilizar una forma recientemente modificada de la teoría de deconvolución de Euler (Método Tilt-Euler mejorado) fue posible detectar varias fuentes de densidad en la cuenca sedimentaria de Goulfey-Tourba, muchas de las cuales están bien correlacionadas con los lineamientos referenciados con el método de Logística Mejorada. Los resultados del método Tilt-Euler mejorado muestran fuentes anómalas a una profundidad de 6 kilómetros debajo de la serie sedimentaria de Bodélé, del Terciario Superior. Las soluciones lineales de Eulers asignadas a las fracturas de los cimientos muestran una profundidad promedio de 1 km. Estos resultados son, sin duda, una contribución mayor en el mejoramiento de la búsqueda de recursos hidrogeológicos en el área del Sahel.
