I may have mentioned before, back in Feb of this year I found a wet rock on the beach with rust on it so I cracked it open thinking there would be an old bolt or metal in black crap, I see some black stuff and rusty metal with some bright metal where I hit it,so thinking it was some kind of slag as it had some kind of black/green glass in places I took it to work to have cut on a band saw, cutting into it only got part of the way through and something was stopping it cutting further so cut another angle part through and chipped out a piece, the black stuff was like crystal with slight green tinge and had cut through metal (started to rust two days later) and brown/ginger rock? but the bit that wouldn't cut all way was a very sparkly metal which didn't rust and very small bits of yellow/green melted looking crystal with the sparkly metal, also some brown patches like dark chocolate, so when i looked through a microscope i was amazed to see a very clear and defined widmanstatten structure appear on the dark brown patches, so it still could be slag of some sort but I'm thinking more pallasite of some sort hopefully, anyway my question is, is it possible that the cutting heat caused the pattern to emerge on the brown patch (poss metal enriched mineral).the specimen is in a university museum that specializes in meteorites since Feb and I've been told it won't be looked at till mid June. Thanks for reading and my apologies for being long winded about it. Sorry no pics at mo.
