Abstract[EN] Flint from Montmaneu's Limestones Formation of Rupelian age (Oligocene) is being here characterized. The analysis of the compositional texture, mineralogy and geochemical features has revealed this flint is highly pure and of microcrystalline texture, with a significant content of moganite. This flint is product of an early diagenetic replacement of limestone from littoral lacustrine facies. This flint was exploited by human populations in a regional range, especially in the early stages of the Neolithic.
[ES] Se caracteriza el sílex de la Formación calizas de Montmaneu, de edad Rupeliense (Oligoceno). El análisis textural, mineralógico y de sus rasgos geoquímicos indica que se trata de un sílex microcristalino, bastante puro, con una proporción significativa de moganita. Es producto del reemplazamiento diagenético temprano de calizas de facies lacustres litorales. Este sílex fue objeto de una explotación regional, especialmente en los primeros momentos del Neolítico.
