The Campanian to early Maastrichtian period is marked by important deposits of limestones in most parts of Tunisia and Algeria. These limestones form the so-called “Abiod formation”. The present paper focuses on the ability of limestones of Feriana Mountain (Jebel Feriana), Central West part of Tunisia, to produce high-quality white cement clinker. From detailed experimental and analytical techniques' data, the limestones of Abiod formation are particularly characterized by a high purity degree and whiteness index. They have a bright white color with a slight visible tendency toward yellow-red. Based on Bogue calculation, X-ray diffraction, and microscopical point-count methods, these particular limestones can conveniently form a white Portland cement when mixed with ∼12.5% of Neogene sands of Maamoura syncline and 7–10% by weight of common Mediterranean kaolins.
