[meteorite-list] Mars Rover Discovers A Potential Meteorite

[Nicholas Gessler]

Hi Jeff, et all,

Looking closely at the new odd rock (aka "meteorite") on Mars, I'm struck 
by what appear to be very clearly delineated ventifact markings.  I have 
seen this a lot in certain desert localities.  They are oriented, as one 
would expect from a desert wind (e.g. the rock sits flat-side down and the 
wind and sand ablation comes across it's length).  One would not expect the 
orientation of flight ablation markings from a meteorite to follow this 
pattern.  They should be somewhat radial.  Has it been suggested that the 
"spherules" are also wind artifacts?  The Derrick Peak Iron shows none of 
these.

Cheers, Nick
