Rhenium-Osmium Isotope Data from a Cretaceous Creek Section in Japan

Kyoei-Sakin-zawa Creek Section in Japan provides a 340-meter-thick Cretaceous stratigraphic record. The dataset contains rhenium-osmium abundance and isotope measurements from organic-bearing siltstone, sandstone, and tuff horizons associated with Oceanic Anoxic Event 1d (OAE1d). Sample collection was funded by an NSF-NERC award in August 2021, and the data is hosted by the British Geological Survey.

Use Cases

• Modeling rhenium-osmium isotope systematics during an oceanic anoxic event based on the described stratigraphic section.
• Correlating geochemical signatures with lithological changes (siltstone, sandstone, tuff) mentioned in the description.
• Calibrating age models for the OAE1d interval using the isotope data.
• Investigating paleoenvironmental conditions from organic-bearing sediments described in the dataset.

Strengths

• Data is tied to a specific, well-described 340-meter-thick stratigraphic section.
• Focuses on a defined geological event (Oceanic Anoxic Event 1d).
• Sample collection was funded by a specific NSF-NERC award in August 2021.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
