Collection of Missouri Core Logs




Dataset contains digital versions of physical core logs housed in Missouri Geological Survey archives. The logs are variable in detail, ranging from simple locations and formation tops to extensive stratigraphic descriptions and chemistry. A portion were done by MGS staff; others were donated by industry, academia, and government entities. The dataset includes logs for mines or undeveloped deposits with occurrences of or potential for critical minerals, along with logs in areas with permissive geology. The dataset comprises three tables: header and location information; formation/stratigraphic top, bottom and written description; and geochemical and assay data.
