National Geochemical Database on Ore Deposits: Legacy data

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: July 16, 2025 | Last Modified: 20211103
There is a growing demand for commodities (elements, compounds, minerals) used in today's advanced technologies. Critical minerals are usually found in ore deposits that are deemed vital to economic and national security. The National Geochemical Database on Ore Deposits: Legacy data (NGDOD) contains chemistry and geologic information for nearly 30,000 historic ore and ore-related rock samples from mineral deposits and mining districts in the United States. Geochemical data sets from various mineral deposits were submitted by geologists of the "Systems Approach to Critical Minerals Inventory, Research, and Assessment" (SACM) within the U.S. Geological Survey Mineral Resource Program (MRP). The data sets represent 15 mineral system types and 42 mineral deposit types.
