Why this rock is probably not a meteorite:

We've seen these before. It does, in fact, resemble an impact breccia - the clasts are not rounded, there's no preferred orientation of the clasts, there's a large variety of clast types, and there's an assortment of sizes. But, when you (I) look close, the clasts look like fragments of terrestrial rocks. The black ones look like shale. Others look like quartz-bearing granitoid rocks. Lunar breccias don't contain red clasts.
  
What is it?

I'm not sure. At first I thought it looked like a volcaniclastic rock, but few of the clasts look volcanic. It may be a debris flow breccia.
