U-Pb Zircon Ages and Hf Isotopic Data from Cobequid Highlands, Nova Scotia

Cobequid Highlands in Nova Scotia, Canada, are the focus of this geochemical dataset. It contains U–Pb isotopic data for zircon analysis obtained via chemical abrasion isotope dilution thermal ionization mass spectrometry (CA-ID-TIMS). The dataset is a 231.9 KB XLSX file authored by Sandra M. Barr and last updated in May 2026.

Use Cases

• Calibrating geological timelines based on high-precision U-Pb zircon ages.
• Investigating crustal evolution and provenance based on Hf isotopic data.
• Correlating sedimentary and volcanic rock units within the Avalonian terrane.

Strengths

• Data is derived from a specific, high-precision analytical method (CA-ID-TIMS).
• Dataset is openly available under a CC-BY-4.0 license.
• File size of 231.9 KB suggests a focused, manageable dataset.

Limitations

• Row count is 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.
