Halpin et al. (2026) Supporting Geological Data for the Charcot Province, East Antarctica

Supplementary geological datasets accompany the paper 'Ediacaran–Cambrian high-strain melt-present deformation of the Archean Charcot Province, East Antarctica' in review with AGU Tectonics. The data includes tables of sample details, field observations, whole rock geochemical data, zircon U–Pb data, zircon Hf-isotope data, and feldspar Pb–Pb data. These tables are provided in XLSX format and were last updated on 2026-07-09.

Use Cases

• Reconstructing the Mesoarchean to Ediacaran–Cambrian geological history of Alligator Island based on zircon U–Pb–Hf geochronology data.
• Analyzing crustal melt sources and interactions using whole rock geochemistry and feldspar Pb–Pb compositions.
• Testing tectonic models for the Kuunga orogenic system during Gondwana assembly based on integrated field observations and geochemical data.

Strengths

• Includes multiple integrated data types: sample details, field observations, geochemistry, and isotopic data.
• Data supports a specific, peer-reviewed study in a major journal (AGU Tectonics).
• Last updated date is precisely recorded as 2026-07-09 23:31:49.976477.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
