Why this rock is probably not a meteorite:

This one is from Canada. Like the previous one, it resembles a lunar breccia. However, the white "clasts" are grains high-potassium feldspar, which is rare on the Moon. Note the trapezoidal shapes and parallel sides. That's the crystal growth form, not an impact breakage form.
What is it?

Probably another terrestrial volcaniclastic rock. The finder and I agree that it would make a nice kitchen countertop.
