John, not sure about that since if human is reforming the meteoritic iron, the lines disappear as he anneals it and doesn't work it cold which would be necessary. If you mean the anvil providing the backing you'd probably have a chance at some point in its lifetime, but they wouldn't be sharp, and it's likely tricky to get it right (I'm thinking Thor's hammer would do it). Krinov depicts a Sikhote Alin example of swirled Neumann lines I think he attributed to the atmospheric entry of that super energetic example, so it is certainly possible to not need asteroid/meteoroid collisions. These ones in Toluca are hard enough to figure out, some could be scratches too... |

Beautiful capture Paul. The clarity of the micro etch is amazing! |

Wow Paul,
A beautiful etch and those Neumann bands are incredible!
Thanks M8 |

Very nice little iron meteorite Paul. Doug and others, are these influences on the alignment of Neumann lines, I assume, only surmised from impacts in space? Or, can man's use of a meteorite iron piece as an anvil or tool, and/or the associated iron-works reheating, etc, cause these variations in the Neumann lines for a particular sample? I confess to less understanding of irons. Distortion of Neumann lines by man being the question. Is it possible? |

What a beautiful macro-window into a beautiful iron that has such a colorful past in meteoritics. It's just brimming with bent Neumann lines that record a long history of violent smash-ups ... Thanks Paul! |
