Microbial growth in actual martian regolith in the form of Mars meteorite EETA79001

open access: yesCommunications Earth & Environment, 2023
Studies to understand the growth of organisms on Mars are hampered by the use of simulants to duplicate martian mineralogy and chemistry. Even though such materials are improving, no terrestrial simulant can replace a real martian sample.

Shear-Induced ringwoodite formation in the Martian shergottite Dar al Gani 670 [PDF]

open access: yes, 2013
Shock-produced melt veins in the Martian shergottite Dar al Gani 670 crosscut large olivine crystals. The upper part of one of these crystals appears to be sheared off and displaced along the shock vein.
