Stages of Palaeoenvironmental Evolution, Climate and Sea Level Change of the Niger Delta, East Equatorial Atlantic: Novelty from Elemental Tracers, Sedimentary Facies and Pollen Records
This Study Used the Comparative Analysis of 3 Gravity Cores (GCs) Obtained from the Shallow Offshore at ~40 M Water Depth to Reconstruct the Morphological Evolution of the Delta (East Equatorial Atlantic). the Focus of This Study is on the Interpretation of Elemental Tracers and their Justification...

This Study Used the Comparative Analysis of 3 Gravity Cores (GCs) Obtained from the Shallow Offshore at ~40 M Water Depth to Reconstruct the Morphological Evolution of the Delta (East Equatorial Atlantic). the Focus of This Study is on the Interpretation of Elemental Tracers and their Justification between These Tracers and Microfossil Data to Understand the Impact of Climate-Sea Level Controls on the Evolution of the Niger Delta during the Late Quaternary.
