The Carbon Mineral Challenge

A worldwide hunt for new carbon minerals

The Carbon Mineral Challenge sets the stage for both professional and amateur mineral collectors to make their mark by discovering never-before described minerals. Researchers predict at least 145 of Earth’s carbon-bearing minerals remain undiscovered. How many can collectors find by 2019?


Carbon Mineral Ecology: Predicting the Undiscovered Minerals of Carbon

“Carbon mineral ecology: Predicting the undiscovered minerals of carbon,” published in American Mineralogist, is now available for download from the University of Arizona Department of Geosciences Website. The Carbon Mineral Challenge was launched as a result of the research in this paper.

Visit this page to see a listing of carbon minerals verified since December 2015. Minerals that were predicted by the paper are marked in red boxes.
