Fusion crust?

[rockpassion]

I have found a big fragment of a rock with a very interesting composition. It has spherules and divers type of green inculsions. What is striking about this rock, is that on one side it has a beige crust and it is really part of the rock and even has contraction cracks and melted brown stuff. Love to hear your opinions and if someone has seen this before.

UPDATE from this find. I have decided to cut this one because i thought it was worth it. And have not cut a rock for 3 years now. The total mass of the stone before cutting was 16 kilo and after 14,9 kilo combined pieces. It looks like black beauty somewhat, and has inclusions which have a martian look to them. included shockveins only visible with 10x loupe. Judge for yourself and give an opinion.

Well after allot of research and study of the rock the first conclusion is that it is indeed a impact melt rock. If it is from mars or from earth i don't know. It is full of impact melt spherules and divers stages of melt and brecciation as can be seen on the photo's.
