Summary:Four arenitic successions, outcropping along the outer margin of the S Appennines, have been studied for their lithostratigraphic and petrographic features. They are in stratigraphic contact with sediments of the 'Complesso Sicilide', and probably represent sequences of the 'Tufiti di Tusa e Arenarie di Corleto' formation. The presence of glaucophane and glaucophane-garnet-bearing schists in all the sequences, together with the abundant andesitic material, granitic rocks and low to medium grade metamorphic lithics, suggests that the sedimentation basin had a very complex shape with various source areas. Calabrian provenance has been suggested for the 'Arenarie di Corleto'; the data, presented here, indicate that ophiolitic rocks, with high P and low T features, and Oligo-Miocene active volcanoes, were involved too. The basin- source area relationships are documented by sequences which are mainly volcaniclastic or siliciclastic, and by the compositional variation along a given sequence. The detrital components of the rocks suggest that in the source areas, rocks similar to those now outcropping in Sardinia-Corsica and Calabria were present; the glaucophane detrital material resembles that found in the 'Falda Piemontese'. If this is true, a more precise relationship between the Alpine chain and the Sicilian basin evolution can be inferred. [R.E.S.]
