[meteorite-list] Nakhlite fragment suggests impact caused water to flow on Mars

[Robert A. Juhl]

Rare fragments of Martian meteorites have been investigated at the 
University of Leicester revealing one of the ways water flowed near the 
surface of Mars....

Hitesh Changela and Dr John Bridges used electron microscopes in the 
University’s Advanced Microscopy Centre to study the structure and 
composition of five nakhlites....

By comparing the five meteorites, they showed the presence of veins 
created during an impact on Mars. They suggest that this impact was 
associated with a 1-10 km diameter crater.

Findings from the research have been published in Meteoritics and 
Planetary Science (Dec. 2010 issue, vol 45).
