Rhenium-osmium abundance and isotope measurements were collected from the approximately 2000-meter-thick Cretaceous stratigraphic section at Nakatengu Creek, Japan. The data, funded by an NSF-NERC award, was sampled in August 2021 from organic-bearing siltstone, siliceous mudstone, sandstone, and tuff horizons.
Use Cases
- Analyze rhenium-osmium isotope ratios to date the Cretaceous tuff horizons within the stratigraphic section.
- Model osmium abundance variations across the organic-bearing siltstone and siliceous mudstone layers.
- Correlate rhenium abundance data with other geochemical proxies for paleoenvironmental reconstruction of the section.
Strengths
- Data originates from a well-defined, approximately 2000-meter-thick Cretaceous stratigraphic section.
- Sample collection was funded by a major NSF-NERC research award.
- Focuses on the analytically precise rhenium-osmium isotope system.
Limitations
- The dataset size, row count, and specific column features are unknown.
- Data is limited to a single geographic location (Nakatengu Creek, Japan).
- The sample collection represents a single time point (August 2021), not a time series.
