In these line graphs of laboratory spectra, it is evident that different minerals have different spectra. The graph on the left shows the typical minerals found in igneous rocks, which are rocks related to magma or volcanic activity. The graph on the right shows iron-bearing candidates for further study and comparison to spectra from the Mars Exploration Rover panoramic cameras on Mars.
