- ERA: Mesozoic
- Period: Tertiary
- Epoch: Wilcox-Eocene
- Age: 60-34 million years ago
- Formation: [Bauxite was a paleosol formed on the surface of the exposed nepheline syenite (GeoLab 4 & 5). It could be included in the 'basal Midway Formation']
- Lithology: Bauxite (Aluminum-hydroxide Paleosol; weathered Nepheline Syenite)
- Original location: 34.548284,-92.501283

- MacNote: Classic bauxite texture reflecting mm to cm-scale aluminum hydroxide nodules. This is the weathering product of soil formation on an exposed surface of nepheline syenite. The nepheline syenite “parent rock” was emplaced during the Cretaceous. Its surface was exposed and altered to an aluminum rich paleosol under humid, tropical conditions during the Tertiary.
- AGS note: Bauxite formed in the Tertiary (Eocene – Wilcox) and is a weathering product of Cretaceous age Syenite
