Planktonic Foraminifera and Sediment Ages from New Britain, Papua New Guinea

Samples from the Rudiger Point-Cape Ruge area, New Britain, reveal two distinct age groups, challenging previous assumptions of a conformable sequence. A volcanolithic sandstone sample, NG34B, is identified as the youngest marine sediment recognized in New Britain, dating to the late Pliocene-middle Pleistocene. The dataset, from Geoscience Australia, correlates planktonic Zone N.18 with a normally magnetized interval.

Use Cases

• Re-evaluating regional stratigraphy based on the described middle and late Miocene age groups.
• Correlating planktonic foraminifera zones with geomagnetic polarity based on the described N.18 zone correlation.
• Studying the youngest recognized marine sediments in New Britain using the NG34B sample data.
• Analyzing sediment age discrepancies in the Rudiger Point-Cape Ruge area as described.

Strengths

• Contains specific sample identifiers like NG34B for traceability.
• Challenges and corrects previous geological assumptions about the sequence's conformity.
• Identifies the youngest recognized marine sediment in New Britain.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in PDF and HTML formats, which may require extraction for analysis.
