Are we overlooking something, page-9

HC, front page is the clearest view of the important bit of the core. If you zoom in there, before it pixalates, there are 2 distinct colours in the pyrohitite. I understand the darker one is iron sulphides, but there is more than one grey/silvery colour, one is clearly lighter than the other.
You do not get nearly as good a view on the cores in the trays. You can zoom to 3-400% on that front picture.
I never mentioned anything about Nova style. Does it have to be the same? Could it be different from a different event ie sometime later melted the same original source but relaid it down in a different configeration?
Thanks for your views.
