| Abstract: | Two profiles have been gravimetrically modelled in the central and eastern parts of the Alboran Sea and Betic Cordillera. The crust in the central part thins from 38 km below the Internal Zones to 18–22 km beneath the Alboran Basin in an area about 30 km wide. The eastern part shows greater thinning, from about 38 to 15 km, distributed over a broader area some 100 km wide. The mode of crustal thinning in the eastern part can be compared with that of a rifted passive margin whereas the central part exhibits a transform style. |
