Northwestern North Carolina's Eastern Blue Ridge hosts this dataset of 40Ar/39Ar age determinations for hornblende and muscovite minerals. The data summarizes results from experiments on samples collected from the hanging wall and footwall of the Idlewild fault, north of Boone, NC. Sarah Hull authored the dataset, which was last updated on June 29, 2026.
Use Cases
- Determining the timing of fault movement based on mineral crystallization ages from the hanging wall and footwall.
- Correlating regional metamorphic events using 40Ar/39Ar results from hornblende and muscovite.
- Reconstructing the tectonic history of the Eastern Blue Ridge province in North Carolina.
Strengths
- Focuses on a specific geological structure, the Idlewild fault, providing targeted data.
- Includes results for two distinct mineral types, hornblende and muscovite, which can record different thermal events.
Limitations
- Row count and sample size are unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Description metadata is limited; actual data quality requires manual inspection after download.
