Description
418-360 million years ago, palaeosol profiles from eastern North America were analyzed to investigate the link between deep-rooting forest evolution and chemical weathering. The dataset, from a NERC grant (NE/J007897/1) managed by the British Geological Survey, was last updated in April 2026. It likely contains geochemical, mineralogical, and palaeontological data from drilled soil profiles comparing pre-forest and forested ecosystems.
Use Cases
Modeling the impact of forest evolution on silicate weathering rates based on palaeosol geochemistry.
Analyzing isotopic and elemental enrichment in soil horizons as a proxy for ancient root activity.
Correlating the formation of pedogenic clays with atmospheric CO2 drawdown during the Devonian period.
Comparing weathering profiles between early vascular plants and deep-rooting forests as described in the research hypothesis.
Strengths
Data is focused on a critical Silurian-Devonian time interval (418-360 Myr ago) for testing a major Earth system hypothesis.
Analysis controls for palaeogeography and provenance effects by using sites in eastern North America.
Research design includes a 'control case' of pre-forest plant weathering for comparison.
Limitations
Row count and dataset scale are 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 after download.
