Tennessee Geological Survey
The mission of the Tennessee Geological Survey (TGS) is to encourage and promote the prudent development and conservation of Tennessee’s geological, energy, and mineral resources by developing and maintaining data bases, maps and technical services; providing accurate geologic hazard assessments; and disseminating geologic information through publications and educational outreach activities.
The TGS is the lineal descendant of the first Tennessee Geological Survey that was established in 1831. It is thus one of the oldest geologic service and research organizations in the country. Our geologists are responsible for surficial mapping, subsurface geologic interpretation, and technical support to those in need of assistance in matters related to Tennessee's geology, particularly to other state agencies and federal and local organizations.
Learn more about TGS activities, including mapping, geologic hazards research, public service and education programs, basic and applied research on geology and critical mineral resources, and publication of geologic information.
Learn about the Tennessee state symbols related to geology: our state rock, gem, mineral, and fossil, Also, view a generalized geologic map of the state and get more inforation about the mineral industry in Tennessee.
The TGS conducts research on the geology and mineral resources of Tennessee and makes the resulting scientific and technical information available to the public through maps and other publications.
The Survey curates a large collection of historical documents relating to the geology and mineral resources of Tennessee. These include maps, reports, field observations, drillers logs, etc. organized in collections by theme. Collections are searchable and most items can be viewed and downloaded.
