How to install Marble?

I recently installed ceramic tiles on a basement slab and now want to install marble in a foyer on top of wood.

What are the main differences that I need to know between what I expreienced with ceramic and the marble?

The foyer has marble in it already that I will rip up prior to installing new marble.

If a wood floor, it needs almost twice the strength, than it does for Ceramic, tell us a little about the floor, joist size, spacing, length of unsupported span, subfloor there now, how many layers, how thick and what is it?

You don't want any lippage with marble, you want a tight joint, 1/16 to 1/8" joints and use un-sanded grout, then seal it all.

type of floor

I am not sure what type of floor is under the current marble tiles. I would guess that it is plywood but it has marble on it right now, I think the floor joists are 16 inches apart. Does it need to be stronger because the marble weighs a lot more?
