This study focuses on identifying and quantifying the mineralogical composition of two diatomite samples collected in the Faya-Largeau region (Borkou, northern Chad) in order to assess their mechanical suitability and potential use as local construction materials. The research is set within the Saharan context, where imported materials remain expensive and difficult to transport, making the development of local geological resources essential. Diatomite, a lightweight sedimentary rock rich in silica originating from fossilized diatoms, is a key material for sustainable construction thanks to its porosity, thermal insulation capacity, and ease of shaping. Two samples from the Tchang-Sousse and Dozanga districts were analyzed using X-ray diffraction (XRD) to identify their mineral phases and determine their behavior during firing and their suitability for local brick production.
