Abstract
The glauconite bearing rocks occurring in lower Eocene deposit of North-East of Tunisia were examined to study the composition and association of glauconite with different minerals. The study was carried out by petrographic investigation, X-ray powder diffraction, Scanning Microscopy with an Energy Depressive System methods. Green grains are a conspicuous component of the studied material. Although resembling glauconitic minerals in thin-section, electron microprobe analyses and acid treatment indicate that the green grains are formed by glauconite core and phosphate rim. The nature of (001), (002) and (003) spacing as found in the XRD patterns obtained for purified sample suggest the presence of glauconite mica mineral. XRD identification is amply supported by results of chemical analyses. Those revel high K and Fe contents in purified sample.
