Planktonic Foraminifera and Polarity Reversals from New Britain Sediments

Samples from the Rudiger Point-Cape Ruge area, New Britain, Papua New Guinea, reveal two age groups: general middle Miocene and late Miocene. A sample of volcanolithic sandstone is identified as the youngest marine sediment in New Britain, dating to late Pliocene-middle Pleistocene. The dataset, sourced from the Australian Ocean Data Network, correlates planktonic Zone N.18 with a normally magnetized interval.

Use Cases

• Refining biostratigraphic zonation based on planktonic foraminifera age groups.
• Correlating sediment ages with magnetic polarity reversals mentioned in the description.
• Studying the geological history and youngest marine sediments of New Britain.

Strengths

• Identifies specific planktonic foraminifera zones (N.18, N.21, N.22) for age correlation.
• Clarifies the age of sediments in a specific geographic area (Rudiger Point-Cape Ruge, New Britain).
• Correlates a biostratigraphic zone (N.18) with a paleomagnetic signal (normally magnetized interval).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic/temporal bias inherent to the sampling location.
