1 PSRDPSRD presents www.psrd.hawaii.edu/May08/MetsOnMars.html Meteorites Found on Mars Dewar area One iron and four possible other pieces of asteroids have been identified since 2005 by the Mars Exploration Rovers. The rock shown here is classified as a IAB complex iron meteorite based on mineralogy and chemical composition. Longest dimension is 31 centimeters.

2 PSRDPSRD presents www.psrd.hawaii.edu/May08/MetsOnMars.html Meteorites Found on Mars Dewar area Barberton (3 centimeters long) is olivine-rich and contains metallic iron. Cosmochemists say it is most consistent chemically with a mesosiderite type of stony-iron meteorite. Santa Catarina (14 centimeters long) is similar to Barberton.

3 PSRDPSRD presents www.psrd.hawaii.edu/May08/MetsOnMars.html Meteorites Found on Mars Dewar area The thermal infrared characteristics shown in the Mini-TES spectra are similar for the known iron meteorite (Meridiani Planum) and two rocks in Gusev Crater (labeled Zhong Shan and Allan Hills). The spectrum for a Martian basaltic rock (labeled Dome Fuji) is distinctly different and shown for comparison.
