[meteorite-list] RFS Picture of the Day Jan. 8 / weird properties of NWA ...

[STARSANDSCOPES at aol.com]

Hi Bob and list,  I agree with Bob.   The "Blue Phase" seems like a different 
material than the "Brown Phase"   Not just magnetic attraction but chondrule 
occurrence and microscopic grain  structures seem different as well.

Could it be a breccia?  Also does  any one have a slice with both materials 
in it?  Not just Blue Phase with  brown staining.

Great micrograph Jeff!

Hi Jeff and  all,
This is a wonderful photo of the type of radial pyroxene  chondrules
I've seen in NWA 2965 and its cohorts. Very nice job Jeff. This  is
certainly a curious meteorite. I've been passing a magnet over  the
slices in my collection and have noticed a few things. The pale,  grey
speckled areas that appear fresh have little to no attraction to  a
rare earth magnet. If I didn't know better, I'd think it was  an
achondrite. However the brown veined sections are clearly attracted
and  the thick dark veins practically pull the magnet out of my hands.
Are the  veins hematite from weathering of iron-rich meteorite or
something else? Any  comments and observations from the group would  be
appreciated.
Thanks,
Bob
