A gravity investigation of the catazonal rock complex at Cabo Ortegal (NW Spain)
Abstract To obtain information about the contact between the isolated complex of Precambrian catazonal rocks of Cabo Ortegal (northwest Spain) and the almost non-metamorphic Paleozoic which surrounds it, a gravity survey has been carried out. The results obtained clearly show that this catazonal complex observed at the surface is part of a massive, deep-rooted structure, which continues to the east beneath the Paleozoic country rocks. Several models are presented that fit the gravity results and which might correspond to acceptable geological interpretations.
