[meteorite-list] Octahedrite formation and Mars

[Thomas Kurtz]

Yes, and in the core of our earth there are Widmanstaetten pattern too.
Unfortunately, we will never dig it out :-)

Subject: [meteorite-list] Octahedrite formation and Mars

I was just reading Meteorites and the Origin of Planets, by John A. Wood.  
In it, I found a statement that octahedrites are formed by exceptionally 
slow cooling over millions of years, such as might be found in the insulated

center of a planetoid.  We already know that Mars has a very weak magnetic 
field and negligible vulcanism, leading some scientists to believe that its 
core has largely cooled.  Might this mean that, if we were able to extract a

chunk of Martian core, it would exhibit an octahedral pattern?  Anyone care 
to speculate on the nickel content of the Martian core?

Mars is one big Wiedmanstatten pattern!
