Lithium Isotope Ratios of Paleozoic Mudrocks from UK and Canada

Geochemical measurements quantify lithium isotope ratios (d7Li) of Paleozoic (541–251 Mya) mudstones. Samples were collected from field locations across Scotland, Wales, England and New Brunswick, Nova Scotia, Canada by the University of Cambridge. The data was collected to understand changes in weathering intensity coeval with the Paleozoic expansion of land plants.

Use Cases

• Modeling silicate weathering intensity based on lithium isotope ratios.
• Correlating geochemical signatures with stages of plant evolution through the Paleozoic.
• Analyzing environmental formation conditions of mudstones based on lithological characteristics.
• Comparing weathering proxies across different geographic regions (UK and Canada).

Strengths

• Data is linked to authoritative geological lexicons (BGS Lexicon, Government of Canada weblex) for detailed formation information.
• Stratigraphic age is standardized according to the GSA geological timescale v.5.0.
• Specific methodologies for sample preparation and analysis are documented in the Metadata Lineage.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific sampled locations in the UK and Canada.
