Mineral Hardness Picks
April 10, 2014 | Geology.com Store
Mineral hardness picks are pencil-like tools that have points made from materials that match the hardness of minerals in the Mohs Hardness Scale. With them you can easily test the hardness of mineral grains in a rock and test the hardness of small-size specimens. In our opinion they are easier to use than pieces of minerals and allow you to obtain more accurate results. They also do not contaminate your specimen with particles of the hardness mineral.

Clay Minerals and a Collision with Europa?
December 15, 2013 | NASA
"A new analysis of data from NASA's Galileo mission has revealed clay-type minerals at the surface of Jupiter's icy moon Europa that appear to have been delivered by a spectacular collision with an asteroid or comet. This is the first time such minerals have been detected on Europa's surface. The types of space rocks that deliver such minerals typically also often carry organic materials."
