The proposed study aims to qualitatively analyze the limestones of Lukunga, within the Lukala subgroup (Neoproterozoic) in the Mbanza-Ngungu region, to determine their potential for industrial valorization. The petrographic and geochemical characteristics, which determine the quality and are crucial factors for identifying industrial valorization potential, have shown that these limestones from Lukunga, in accordance with existing international standards, possess features suitable for valorization in various industrial sectors, such as the manufacturing of construction materials and lime production. However, they remain unsuitable for cement manufacturing and the chemical industry due to their relatively high silica content.
