| dc.description | From a study of aeromagnetic anomalies over parts of the Benue Trough, Nigeria, an attempt is here made to estimate the depth to the basement underneath the Benue Trough and consequently the thickness of sediments in the area. Several aeromagnetic profiles have been taken across the trough and two-dimensional interpretation of these carried out using non-linear optimization and interactive techniques in an effort to estimate the nature and depth to the basement underneath the Benue Trough. The results of this interpretation show that the Benue Trough is underlain by a basement of variable topography. The depth to the basement and consequently the thickness of sediments filling the trough is estimated to vary between about 0.5 km and about 7 km. | en-US |
| dc.description | A partir de un estudio de anomalías aeromagnéticas sobre partes de la hondonada de Benue, Nigeria, se hace aquí un intento de estimar la profundidad del basamento bajo dicha hondonada y consiguientemente, el espesor de los sedimentos en el área. Se han determinado varios perfiles aeromagnéticos a través de la hondonada y se ha llevado a cabo una interpretación bidimensional de estos utilizando la optimización no-lineal y técnicas interactivas en un esfuerzo por estimar la naturaleza y profundidad al basamento bajo la hondonada. Los resultados de esta interpretación muestran que bajo la hondonada Benue subyace un basamento de topografía variable. La profundidad al basamento y consiguientemente el espesor de los sedimentos que la llenan se estima que varían entre unos 0.5 km y 7 km. | es-ES |
