Possible fusion crust??


Recommended Posts

Found this rock in Upper Michigan this weekend and see it has what appears to be remnants of fusion crust - dark brown and some black colored crust which is paper thin. The first pic also shows rock fragments (just left of center) that is in the matrix and looks like breccia. I would appreciate any thoughts on this possibly being a meteorite and fusion crust.  (very heavy and attracts magnet)

I don't really know, my geology isn't that great, but a quick google search turns up lots of results, especially for volcanic basalt breccia.  Give the glacial activity in north Michigan that rock could have come from almost anywhere... hopefully someone else can chime in.

Interesting bit... It would be a good idea to get those chondrules tested for nickle content...Worth checking just for fun!

Cheers, Unc
