This ScienceBase community represents the National Digital Catalog of the National Geological and Geophysical Data Preservation Program (NGGDPP). The National Digital Catalog includes metadata records describing geological, geophysical and biological collections and data managed by state geological surveys and USGS. These collections include rock samples, thin sections, field notebooks, photographs, maps, datasets, and others. Collections are described using metadata elements identified by the NGGDPP as important for discovering, understanding, accessing, and using physical collections. Contact and access information is provided for collections and individual samples to enable users to access information and material.
