Macrostrat aims to become a community resource for the addition, editing, and access of macrostratigraphic, lithological, environmental, and economic data. It is designed to facilitate the testing of hypotheses related to the spatial and temporal distribution of sedimentary, igneous, and metamorphic rocks and proxy data extracted from them. Interactive applications built upon Macrostrat are designed for educational and research purposes.
