Graphite deposits in the United States | U.S. Geological Survey
Graphite occurs in the U.S. as disseminated flake graphite deposits and as graphite veins. Globally, most currently mined flake graphite deposits contain at least 8 to 12 percent graphitic carbon in deposits larger than 0.5 million metric tons (Robinson and others, 2017). In comparison, the Graphite Creek deposit in Alaska contains a measured ...

Graphite: A mineral with extreme properties and many uses
Graphite is a mineral that forms when carbon is subjected to heat and pressure in Earth's crust and in the upper mantle. Pressures in the range of 75,000 pounds per square inch and temperatures in the range of 750 degrees Celsius are needed to produce graphite. These correspond to the granulite metamorphic facies.
