[meteorite-list] Odd layered feature in NWAXXX specimen

[tracy latimer]

I was going through a batch of unclassified NWAXXX rocks and putting the small ones in mylar baggies for giveaway.  One of the specimens caught my eye; surface features make it seem to have many thin layers, like slate or shale.  It is attracted to a magnet, so chances are good it really is a meteorite and not an erratic that got tossed into the hopper, but I am at a loss as to what might naturally produce this type of effect.  Any ideas?
