Marble is in general terms metamorphosed limestone, mostly composed of recrystallised carbonate minerals. So the bulk of marble is just CaCO3.

Chalk is a soft, white, porous, sedimentary carbonate rock, a form of limestone composed of the mineral calcite. Calcite is an ionic salt called calcium carbonate or CaCO3. The chemical formula for chalk is CaCO3.
