My feeling right now is that it is fairly random. It seems like it destroys blocks below it and to the sides, but not above. I have noticed that sometimes the trasnmuted material is close to where the Brown Mob exploded and sometimes at the outer limits of the blast. One thing I didn't mention is that usually when it explodes it causes the Transparency Bug to occur. If you quickly drill any block the transparency goes away, but some of the floating blocks get stuck inside of the remaining blocks and you can't collect them. It's all very strange.
