Marble is calcium carbonate (the same stuff as chalk or limestone) that has been subjected to very high temperatures and pressures; what is called a metamorphic rock. Granite is an igneous rock made from slowly cooled magma (hence the large crystals). For counter tops, polished is better because it is less susceptible to scratches than honed finish.

Chalk is made from the same mineral as limestone but in a different way. Chalk hills are usually called 'downs' and have dry valleys that were formed when the ice from the last ice age melted. Chalk is porous so surface water seeps into the ground and drainage density is very low.

There are many different names used for limestone. These names are based upon how the rock is formed and its density, appearance, and chemical composition. Some of the more commonly used names are chalk, travertine, and marble. Chalk is a soft limestone with a fine texture. Travertine is a limestone that forms by evaporation of an aqueous (water) solution of CaCO 3, often in caves. It can ...
Get PriceThe difference between travertine and limestone occurs when the layers of sedimentary rock end up being subjected to more pressure and heat, making it limestone instead of travertine. When comparing travertine vs limestone, travertine just accumulates the layers without the heat and pressure necessary to convert it to limestone. You wouldn't ...
