Data for: What caused Earth's largest mass extinction event? New evidence from the Permian-Triassic boundary in northeastern Utah
This geochemistry data comes from a newly discovered extraordinarily well-preserved stratigraphic section of the Permian-Triassic boundary in Utah. The data features a comprehensive geochemical dataset from northeastern Utah, assembled from a unique and remarkable 9-meter section of rock in Sheep Cr...
