Navigating a slippery slope at Graphite Creek Deposit
Geologist, Sue Karl, at Graphite Creek Deposit on the Seward Peninsula, Alaska. She is making field observations and measurements about the flake graphite deposit and the surrounding host rocks. These observations were used in developing a model of flake graphite genesis. Graphite is a critical mineral which the US depends entirely on imports. The USGS has been studying the geology of graphite deposits to learn more about how they form and where they are likely to be found, to improve the future domestic supply chain.
