Planktonic Foraminifera and Polarity Reversals in New Britain Sediments

Samples from the Rudiger Point-Cape Ruge area, New Britain, reveal two distinct age groups, correcting a previous assumption of a single late Miocene-earliest Pliocene sequence. The dataset includes a sample of volcanolithic sandstone identified as the youngest marine sediment yet recognized in New Britain. It was published by Geoscience Australia Data, with a last update recorded for 2026-04-30.

Use Cases

• Re-calibrating regional stratigraphic models based on corrected age groups for middle and late Miocene sediments.
• Correlating planktonic foraminifera zones (e.g., N.18) with intervals of normal magnetic polarity.
• Identifying the youngest known marine sediment in New Britain from the late Pliocene-middle Pleistocene sample NG34B.

Strengths

• Includes a specific sample (NG34B) identified as the youngest marine sediment recognized in New Britain.
• Correlates planktonic Zone N.18 with a normally magnetized interval, linking biostratigraphic and paleomagnetic data.

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 bias inherent to the specific study area in New Britain.
