Title

Archived geochemical, geospatial, and geochronological data associated with individual rock units contained within stratigraphic columns (covering North America and New Zealand) in the Macrostrat.org database (NERC Grant NE/L002507/1)

Abstract

Macrostrat.org is a live database project collecting geochemical, geospatial, and geochronological data associated with specific rock units within stratigraphic columns with a geographic footprint. The data in Macrostrat is an aggregate of previously reported measurements in the literature. The database is constantly updated, expanded, and improved. Hence, data are archived (5-2-23) in this file for posterity in support of the manuscript titled "Evolution of the crustal phosphorus reservoir" (Walton et al., 2023). In all measurements in the data file: ages are in millions of years (Ma) and elemental compositions are in wt%. Further details of all definitions and standards in Macrostrat data reporting are permanently available at https://macrostrat.org/api/defs. Macrostrat data are useful for weighting geochemical data by the relative areal and volume abundance of the rock units from which they derive, helping to address questions of (over/under) sampling-induced bias. Data in these files represent direct exports from Macrostrat.org via the API root, supplemented with data from Reinhard et al (2017). Unit areal extents for data from Reinhard et al 2017) are approximated with the relevant Eon average from Macrostrat.org. Macrostrat.org is maintained by Shanan Dr Peters, Dr Daven Quinn, and the hard work of many others (https://macrostrat.org/#people).

Quality and validity

Lineage

Macrostrat.org is a database of rock chemistry, geometry, age, and lithology. The database is actively maintained and so the data used in supporting the manuscript is archived here permanently. The authors recommend that new studies should repeat our approach using newly downloaded rather than archived data, as metadata is constantly being added to Macrostrat as global surface area coverage is improved.
