This paper deals with the intriguing and still not extensively treated evidence of an high amplitude, long wavelength magnetic anomaly covering a large area of the north-eastern – central Adriatic Sea (Croatian offshore, Fig. 1). The presence of intruded gabbroid rocks in the Croatian archipelago (Jabuka Island, Fig.1) represents an additional open question. A 2D geophysical model and the derived conceptual geological section will be presented as realized along two sections (the NW-SE Adria profile and the WSW-ENE L’Aquila-Sibenik profile) which cross cut the magnetic anomaly (Fig.1). The model has been carried out by integration of surface and geophysical data (many of them already published), the latter concerning magnetic and gravimetric anomalies, tomographic and heat flow data. These data have been merged in an integrated data-base by using the MOVE software while geophysical modelling have been done using GM-SYS 4.7.

Abstract
This paper deals with the intriguing and still not extensively treated evidence of an high amplitude, long wavelength magnetic anomaly covering a large area of the north-eastern – central Adriatic Sea (Croatian offshore, Fig. 1). The presence of intruded gabbroid rocks in the Croatian archipelago (Jabuka Island, Fig.1) represents an additional open question. A 2D geophysical model and the derived conceptual geological section will be presented as realized along two sections (the NW-SE Adria profile and the WSW-ENE L’Aquila-Sibenik profile) which cross cut the magnetic anomaly (Fig.1). The model has been carried out by integration of surface and geophysical data (many of them already published), the latter concerning magnetic and gravimetric anomalies, tomographic and heat flow data. These data have been merged in an integrated data-base by using the MOVE software while geophysical modelling have been done using GM-SYS 4.7.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
