Eagle Ford Shale in South Texas provides a dataset of rhenium isotope compositions, concentrations, and associated geochemical measurements from bulk rock digestions. The data was collected to compare isotopic composition before and after oxidative weathering, using samples from drill core Innes-1 and outcrop sections DR5 and DR12. Measurements were obtained via MC-ICP-MS and Rock-Eval pyrolysis.
Use Cases
- Analyze rhenium isotope compositions across coeval strata to study oxidative weathering effects.
- Correlate rhenium concentrations with total organic carbon concentrations to investigate geochemical relationships.
- Model the isotopic composition of Re using titanium concentrations as a provenance or dilution proxy.
- Compare rhenium concentrations and isotope data from drill core and outcrop samples for spatial variability.
Strengths
- Includes multiple geochemical variables: rhenium isotopes, rhenium concentrations, total organic carbon, and titanium concentrations.
- Data generated using precise analytical methods: MC-ICP-MS with a tungsten spike correction and Rock-Eval pyrolysis.
- Samples sourced from specific, documented locations: drill core Innes-1 and outcrop sections DR5 and DR12 in South Texas.
Limitations
- Sample size and row count are unknown, limiting statistical power for some analyses.
- Geographic scope is restricted to the Eagle Ford Shale in South Texas, USA.
- Data freshness is uncertain as the last update is a future date (2026-03 26).
