Greenland Geochronology Database

The Greenland Geochronology Database is a systematic compilation of published U-Pb geochronological data from Greenland. The dataset integrates age determinations from a wide range of scientific publications and normalises isotopic ratios and uncertainties into a consistent format, with all analytical errors reported at the 1 sigma level. Ratios have been verified against reported ages and corrected where necessary to ensure internal consistency. The database is structured to enable efficient querying and cross-comparison of geochronological information derived using different analytical standards.

The dataset is a compilation of published geochronological data. Users must provide appropriate citation of both the Greenland Geochronology Database and the original publications in which the data were first reported. The dataset is provided without warranty regarding completeness or absence of errors. GEUS assumes no liability for interpretations or decisions based on the dataset. For scientific applications, users are advised to consult the original publications for details on analytical methods, standards and data processing.

Supplemental Information
The dataset represents a harmonised compilation of published U-Pb geochronological data and does not contain primary laboratory measurements. The original analyses were produced using different analytical techniques and standards, which may vary between publications. The normalisation to consistent isotopic ratios and 1 sigma uncertainties aims to ensure internal coherence and comparability; however, the dataset does not replace the original publications, which should be consulted for detailed geochronological or methodological assessments. The database is designed as a dynamic reference resource and may be updated as new data are published or existing interpretations are revised.

Statement
The dataset was established through systematic collation of published U-Pb geochronological analyses from the scientific literature. Original isotopic ratios and uncertainties were recast into a consistent format, with all errors reported at the 1 sigma level. Ratios were verified against reported ages and corrected where inconsistencies were identified to ensure internal coherence. The dataset represents a compilation rather than primary laboratory measurements.
