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.
