Hello Matthias, Do you know of any references regarding how armored chondrules form? I believe, the comprehensive study of the inner/outer crust of the metal, as well as the two inner/outer crusts of the matrix, might lead to a trail/solution. They are so cool, how?? That's it, John ______________________________________________ Meteorite-list mailing list Meteorite-list@meteoritecentral.com https://pairlist2.pair.net/mailman/listinfo/meteorite-list
