This sector exhibits Middle and Upper Jurassic deposits, developed in biohermal (in situ spongalgal, coralgal reefs and stromatolits) and biostromal facies. All around Hârșova, on the right bank of the Danube, the landscape is dominated by ruiniform shapes of this spongalgal limestones, formed through differential dissolution. The Callovian and Oxfordian fossil fauna contents are of biostratigrafic and paleoecological importance.
