Phanerozoic Magnetostratigraphy: A Critique of Paleomagnetic Timescale Coverage

A critique of magnetostratigraphic coverage for the Phanerozoic era is presented by the Australian Ocean Data Network. The document analyzes constraints from the Cambrian to the Recent period, noting sparse coverage for the Cambrian to Early Carboniferous and better constraints for the Late Carboniferous to Recent. The last update was recorded on 2026-06-04.

Use Cases

• Calibrating geological timescales based on described magnetostratigraphic constraints.
• Analyzing the coverage and reliability of paleomagnetic data for different geological periods.
• Studying the Permo-Carboniferous Reverse Superchron (PCRS) and its polarity subchrons.
• Integrating magnetostratigraphic data with biostratigraphic control and marine magnetic anomalies.

Strengths

• Analysis covers the entire Phanerozoic eon, from Cambrian to Recent.
• Specific periods like the Triassic to Recent are described as having well-established constraints.
• Document is hosted by the authoritative Australian Ocean Data Network.

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 temporal/source bias inherent to the critique's scope.
