Composition and properties of glass obtained from Early Cretaceous Sidi Aich sands (central Tunisia)

The present work describes the chemical–mineralogical characterization of Barremian sand deposits. These Sidi Aich sands are observed exclusively in central Tunisia; in the Central Atlas two major domains might be discriminated: north–south axis and southern Atlas. In the collected raw samples, quar...

Description
Summary:The present work describes the chemical–mineralogical characterization of Barremian sand deposits. These Sidi Aich sands are observed exclusively in central Tunisia; in the Central Atlas two major domains might be discriminated: north–south axis and southern Atlas. In the collected raw samples, quartz and potassic feldspars are depicted with percentages that reach 30 wt.%. The chemical and XRD analyses confirm the existence of K-feldspars. These compounds are known fluxing agents. Since the amount in heavy minerals (
