Caracterización petrológica del sílex de la Formación Calizas de Montmaneu (Sector oriental de la Cuenca del Ebro)

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....

Description
Summary: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
