A sample of gas hydrates collected from Mallik, Canada. Gas hydrates are naturally-occurring “ice-like” combinations of natural gas and water that have the potential to provide an immense resource of natural gas from the world’s oceans and polar regions.

A sample of finchite, a newly discovered uranium mineral. Finchite is the yellow material on the surface of the rock. Finchite is found in the late Pleistocene sediments deposited during the Illinoian glacial stage.
