I was looking through some of Michael Farmers auctions on Ebay
and one piece made me puzzled.
It was a 7 kg oriented Sikhote-Alin that had flowlines. I thought that
all the shrapnel pieces were created when larger meteorites impacted
and tore the metal apart.
But flowlines should mean that this shrapnel were created in flight.
My question is if there are shrapnel pieces created in flight?
I have a neat oriented Sikhote-Alin in my collection, complete with
flowlines, thumbprinting and even fractured surfaces and teared metal.
It isn't a shrapnel and there still are some crust on the leading edge
with finer flowlines in the crust. If a shrapnel piece would have
crust with flowlines then I would be convinced that it was created
in flight but isn't it possible that there could be similar structures
without crust created when it hits the ground?
I'm just curious as this is the first shrapnel I've heard about with
flowlines.
Regards, Göran
