   Mike,   
      
   Thank you for the reply and comments.   
      
   I very much wish I could view the image at higher magnification without loss   
   of resolution   
   - or that the MER would acquire a closer image.   
      
   In looking at the image again - I agree that the black rectangular area is not   
   a perfect a   
   perfect square - although it closely approximates one.   
      
   Although I am not even an amateur rock guy, perhaps just more than casually   
   curious - that   
   such an indication on a fracture surface is most interesting - how can this   
   occur   
   naturally?   
      
   Also, the demarcation between the face adjacent areas of gray and black   
   appears rather   
   sharp - not blended.  A better resolution image at closer range would remove   
   any doubt   
   about what is being observed.   
      
   The following is the first post to this thread from you - at least that I have   
   seen.   
      
   Not sure why other posts would have been blocked - I appreciate your   
   thoughtful response   
   and look forward to your additional comments.   
      
   Best,
