Writeup from MB 109:

Meridiani Planum 007        2.121°S, 5.532°W

Mars

Find: 1 Oct 2009

Classification: Iron meteorite (IAB complex)

History: The Mars Exploration Rover Opportunity encountered a pitted boulder on sol 2022 along the rover’s traverse to Endeavour crater.

Physical characteristics: The rock appears to be extensively weathered, some parts appearing deeply pitted with large spires whereas smooth areas on the surface show an eroded Widmanstätten pattern (Ashley et al., 2011). Dimensions: 50 × 24 × 20 cm. It would have an approximate mass of ~245 kg if it were a hemisphere, but it is more likely closer to half this mass (Chappelow and Golombek, 2010).

Geochemistry: Mössbauer analyses showed the dominance of metallic iron-nickel phases, with resolvable kamacite and taenite (Fleischer et al. 2010a).

Classification: Iron, Ni, Ge, and Ga abundances measured using the Alpha Particle X-Ray Spectrometer (APXS) are consistent with an iron meteorite in the IAB Complex (Fleischer et al. 2010a; Ashley et al. 2011). Pancam color imaging and APXS composition shows the presence of a dark surficial coating similar in hue, composition, and occurrence to that found on Meridiani Planum 001 (Heat Shield Rock) (Johnson et al., 2009; Fleischer et al., 2010a).
