Crustal structure in the Campanian region (Southern Apennines, Italy) from potential field modelling

Abstract We present a 3D model of the main crustal boundaries beneath the Campanian region and the onshore and offshore surrounding areas, based on high-resolution potential field data. Our main objective is the definition of the main structural interfaces in the whole Campanian region from gravity...
