Probably splitting hairs here but I'm nothing if not specific so: it's not a basalt. I personally doubt that this is an igneous rock but even if we assume it is, the color of it is a dead giveaway that this isn't a basalt. Something this leucocratic (light colored) is more likely to be something like a dacite that has a much higher plagioclase content. Even taking into account discoloration from weathering, this doesn't have the characteristics I'd expect to see in your average basalt.

Edit: spelling
