[meteorite-list] NWA 2371 Crust micrographs with crystal structure. Check it out!

[STARSANDSCOPES at aol.com]

Hi list,  Tom Phillips here,  I have some crust micrographs taken  in 
reflected cross polarized light of a thick slice of NWA 2371 an H4.  The  
heating/cooling caused the crust to crystallize like nothing I have seen  before.  

I haven't posted them to the Gallery yet but it is well  worth the time to 
email me and I will send some shots in an email.

I  would welcome any thoughts on this and if any one has noticed it before.   
It really is cool!

Hello  all,

Looking at crust on various thin sections under the microscope it is  very 
common to see a mineral, such as an olvine crystal, on top of the  crust.  It 
is not as even as it appears to our naked eyes.  A few  old photographs on my 
website illustrate this fairly  well...
