Antarctic Peninsula Crystalline Rock Geochemistry And Geochronology

A growing database contains a suite of crystalline rocks, primarily granitoids and quartzites, collected from the Antarctic Peninsula and adjacent islands. The dataset includes geochronology and geochemistry data for some samples, funded by NSF awards to David Barbeau and Sidney Hemming. Associated metadata was scheduled to remain private until September 2015 to facilitate publication.

Use Cases

• Analyze geochemistry data to classify rock types like granitoids and quartzites.
• Use geochronology data to date tectonic events in the Antarctic Peninsula region.
• Correlate sample locations with geological maps to study the distribution of crystalline rocks.
• Compare geochemical signatures of mafic intrusive rocks with other Antarctic samples.

Strengths

• Includes multiple rock types: granitoids, quartzites, gneisses, schists, volcanic rocks, and mafic intrusives.
• Data funded by multiple NSF awards, indicating peer-reviewed scientific backing.

Limitations

• Sample access and data use were limited through 2015 for a subsequent project.
• Metadata was private until September 2015, restricting immediate public analysis.
• The exact number of samples, rows, and data columns is unknown.
