> Check out the concentric bands in this photo of my Nevada find First of all: Congrats on that exceptional find!

Somehow the shock process may have been interrupted or stopped and the meteorite been ejected from its parent body before it underwent complete shock darkening: a shock melt breccia in the making ... ?
