Gravity data on the Central Pyrenees: a step forward to help a better understanding of the Pyrenean structures

In this work, we present new Bouguer and residual anomaly maps of the Central Pyrenees calculated from 3590 stations, which 1141 are observations acquired surveys performed between 2018 2019. The most prominent feature is long wavelength elongated minimum in its central part that continues to W ends towards E with a positive gradient seems envelope minimum. Other short medium minima superimposed, some placed over batholithic outcrops. Bouguer, main relative related outcrops batholiths or interpreted buried granites except for South La Maladeta Granite, associated Triassic evaporitic accumulations. These (shown on Main Map) will help characterizing Permo-Carboniferous Pyrenees, particular Andorra Mont-Louis order add constraints mechanism their emplacement.
