- •
Outcrop logging and sampling of the section were systematically done from base to top.
- •
Field samples were analyzed and logged under the microscope.
- •
Detailed biostratigraphic age/correlations of the sediments was achieved.
- •
Paleoenvirionments of deposition of the sediments were ascertained using palynomorphs of environmental value.
- •
Paleosalinity and paleoclimatic conditions of the sediments were reconstructed.
