I am a little curious about something.....

I heard that the sikhote-alin meteorites have a Widmanstatten Pattern
although large and difficult to see.

I have also heard that the regmaglypts are created when a molten piece cools
while airborne.. As nearly all the fragments I have seen have regmaglypts I
assume all these pieces have been molten.

So after melting and recooling on Earth do they really maintain the pattern
or is it only present on pieces large enough not to melt?
