Dear Dave, Very good micro-photographs. I have seen these on many pallasites under my microscope. Analysis has shown me that the rust looking trails are the remains of iron oxide solutions from galvanic corrosion action under either surface coatings or Olivine xls. They micro blast off easily. You may have heard that I have shown that many of our meteorites are loaded with water after plunging into earth soil that contains water vapor and with 14.7 #/sq" shoves water vapor into the shocked meteorite. Oxygen and other elements enter the meteorite and then have a field day supporting the earlier galvanic action process. My goal is to help our knowledge of meteorite preservation be a universal capability.

Please enjoy these microscopic photographs of my four pallasite slices: http://free.radio.su/meteorites.html These are taken at 100X and 400X with a ProScope, at or near the olivine-iron boundary. I'm pretty curious about some of these features, especially on the Brenham. Is it just surface rust?
