Hi Matt, My best view of the veins is by photography, which is not my best talent, but the 'shine' of the veins match the 'shine' of the FeNi flecks, so I am making the assumption they are of the same minerology. I know - when I assume I make an 'ass' of 'u' and 'me'. LOL I will have to look into this further to be sure. Did you see the closeup picture at;
http://www.meteorite-dealers.com/images/northbranch4-2b.jpg It does not show it, but just now I put on my strongest glasses and used a loupe to look closer. The vein does cross the edge of the partslice and on the opposite side looks more like a shock vein, not being filled full with the 'shiny stuff'. Would FeNi flow into a shock vein during the higher temp stage of atmospheric entry? Would hematite? I don't know how to explain this as I am relatively new to observing details of slices and am only stating what I see. Any enlightenment would be very welcome.
