I'm no geologist, but I was under the impression that "bedrock" generally refers to this harder type of rock. It is not just a word for any rock that things are built on. Maybe I'm wrong though. I've never heard London referred to as being built on top of bedrock in the same way I've heard it of NYC.

Bedrock is a generic term for the hard(er) layer of rock underneath the softer stuff. Manhattan has very tough bedrock (schist) London has very soft bedrock (chalk and London Clay) - and it's also deeper
