Landsat 9 is the latest in a prestigious line of satellites that have been watching our planet for nearly 50 years. They have monitored changes on land and made that information freely available to users around the world.

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.

Scenic view of the Seward Peninsula, Alaska. Photo taken from a ridge above Graphite Creek, looking northwest towards the Imruk Basin. This area of the Seward Peninsula holds the largest graphite deposit in the US known as the Graphite Creek Deposit.

View of the Kigluaik Mountains gneiss dome which is the location of the Graphite Creek Deposit. The rocks of the gneiss dome were metamorphosed to as high as granulite facies during the middle Cretaceous (ca. 100 – 90 Ma), forming flake graphite ore in the process.

The 26th annual Mineral Commodity Summaries report from the U.S. Geological Survey National Minerals Information Center is the earliest comprehensive source of 2020 mineral production data for the world.

The United States continues to rely on foreign sources for some raw and processed mineral materials, including some critical minerals. This map shows the countries that supply mineral commodities for which the United States was more than 50% net import reliant in 2020. 

Map indicating flight area for Trans-Pecos aeromagnetic and radiometric survey. The survey area includes parts of El Paso and Hudspeth counties, Texas, and Otero County, New Mexico. Flights will begin in November 2020 and are expected to conclude in mid-January 2021. 

Mineral elements provide the color in fireworks. Barium produces bright greens; strontium yields deep reds; copper produces blues; and sodium yields yellow. Other colors can be made by mixing elements: strontium and sodium produce brilliant orange; titanium, zirconium, and magnesium alloys make silvery white; copper and strontium make lavender.
