In this paper a geothematic map at 1:180,000 scale of the Daunian Subapennine, a sector of the Southern Apennines Chain, located in the Apulia Region (Southern Italy) is presented.

For this reason, the geological sheets do not provide an univocal geo-lithological framework of the whole area. The uncertain interpretations of the geological terms contained in the different geological sheets have been checked and u...
