Helium pycnometry measurements for 7 cored rhyolitic obsidian cylinders from Hrafntinnuhryggur, Iceland. The data includes sample mass and geometry, with density calculated for experiments in the study Seropian et al (2022). The dataset was collected and analyzed at the University of Liverpool.
Use Cases
- Calibrating material density for experimental models based on the described pycnometry data.
- Analyzing the relationship between sample mass and volume for rhyolitic obsidian.
- Validating physical property measurements for geological samples using the described helium pycnometer method.
Strengths
- Measurements are for 7 representative samples, providing a focused dataset.
- Data collection methodology is explicitly described, involving a scale, caliper, and helium pycnometer.
- Dataset is linked to a specific published study (Seropian et al, 2022).
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Freshness is unverified as the last update date is unknown.
