[ES] Este trabajo tiene como principal objetivo mostrar una compila-ción de datos geofísicos (datos gravimétricos, magnéticos y magne-totelúricos) para caracterizar la estructura de la corteza superior y la geometría en profundidad de los granitos de La Maladeta y Bono (Pirineo Central). El granito de La Maladeta se interpreta como un complejo granítico asimétrico de 8 km de espesor y formado por dos cuerpos diferenciados. Por otro lado, el granito de Bono presenta una geometría laminar y un espesor menor de 1.5 km. Ambos gra-nitos presentan un volumen en profundidad mayor que el que se observa en superficie.

[EN] This work aims to show a compilation of geophysical data (gravi-ty, magnetic and magnetotelluric data) to determine the upper crus-tal structure and geometry at depth of the La Maladeta and Bono granites (Central Pyrenees). La Maladeta granite is interpreted as an asymmetric granitic complex 8 km-thick formed by two differen-tiated bodies and with a clearly northwards deepening. By contrast, the Bono granite shows a laminar geometry and its thickness does not reach 1.5 km. Both granites show higher areal extension at depth than that showed by their outcrops at surface.
