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!
