Abstract

This work aims to show a compilation of geophysical data (gravity, magnetic and magnetotelluric data) to determine the upper crustal 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 differentiated 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. ---------------------------------------------------------------------------------------------------------
Este trabajo tiene como principal objetivo mostrar una compilación de datos geofísicos (datos gravimétricos, magnéticos y magnetotelúricos) 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 granitos presentan un volumen en profundidad mayor que el que se observa en superficie.
