Determination of Provenance and Tectonic Settings of Niger Delta Clastic Facies Using Well-Y, Onshore Delta State, Nigeria

Figure 5

Discriminant function diagram for the provenance signatures of sandstone mudstone suites using major elements after Roser and Korsch [9]. The fields were dominantly mafic, intermediate, and felsic igneous provenances. Also shown is the field with quartzoze sedimentary provenance.
