The structural and magnetic fabric study of the Marimanha granite (Axial zone of the Pyrenees, Catalonia),
provides new data to characterize the zonation and the internal structure of the pluton. The Marimanha
granite intrudes Cambro-Devonian metasediments of the Axial zone of the Pyrenees. The zonation of low
field magnetic susceptibility is consistent with the petrological zonation of the igneous body and indicates
a concentric arrangement of rock types, with more basic compositions at the external areas. By means of
measurements of the anisotropy of the magnetic susceptibility, we have inferred the magmatic fabric of
this pluton. Magnetic foliations and magnetic lineations are concentric and parallel to petrografic contacts
in map view. The dominant strike of magnetic foliation is NE-SW with steep dips. The dominant magnetic
lineation also trends NE-SW with shallow plunges to the NE and SW. This orientation agrees with the
slightly elongated shape of the pluton in the NE-SW direction. This relationship suggests an intrusion
contemporary with a E-W transpressional regime
