About

Summary

Macrostrat is a platform for the aggregation and distribution of geological data relevant to the spatial and temporal distribution of sedimentary, igneous, and metamorphic rocks as well as data extracted from them. It is linked to the xDD (formly GeoDeepDive) digital library and machine reading system, and it aims to become a community resource for the addition, editing, and distribution of new stratigraphic, lithological, environmental, and economic data. Interactive applications built upon Macrostrat are designed for educational and research purposes.

Collaboration

Our small team has worked hard to compile, format, and make data available via Macrostrat. We strongly encourage and welcome active collaborations, both scientific and geoinformatic. All data are provided freely on under a CC-BY-4.0 license.

Funding

Major Macrostrat data infrastructure development was supported by the US National Science Foundation (EAR-1150082, ICER-1440312), with ongoing support for data acquisition supported by NSF EAR-1948843 and ICER-1928323. Continuous and ongoing support has also been provided by the UW-Madison Department of Geoscience. If you use Macrostrat and like what we do, please consider helping out with a donation. Every contribute helps us to maintain infrastructure and keep improving.

API

All data contained in the Macrostrat database are freely available via our Application Programming Interface (API), which provides a convinient way to retrieve data for analysis or application creation. For more information head over to the API root to explore available routes.
