These images, made from data obtained by Curiosity's CheMin, show the patterns obtained from a drift of windblown dust and sand called 'Rocknest' and from a powdered rock sample drilled from the 'John Klein' bedrock.
This graphic shows results of the first analysis of Martian soil by the CheMin experiment on NASA's Curiosity rover. The image reveals the presence of crystalline feldspar, pyroxenes and olivine mixed with some amorphous (non-crystalline) material.
