Note that I'm not saying it's limestone all the way down, but there are chucks of marble (formerly limestone) down there. If you want to be really extreme, there is an article where the authors say:
...carbonate sediments were subducted into the upper mantle...
Upper mantle is 200-300 kilometres deep. And you know what? That's only the ones we know of. Who knows, there might be some limestones that were subducted all the way down to the core-mantle boundary, almost 3000 kilometres deep.
