How do you recognize limestone and marble? The main difference between limestone and marble is that limestone is a sedimentary rock, typically composed of calcium carbonate fossils, and marble is a metamorphic rock. Limestone forms when shells, sand, and mud are deposited at the bottom of oceans and lakes and over time solidify into rock.
Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO 3 ) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite .
That happened when sheets of ice plucked the stones from their bedrock, simultaneously grinding off their originally rough edges. The rocks eventually landed primarily in the Northwestern part of Michigan and its lower peninsula. When these stones are dry, you could easily mistake it for limestone.

Marble, on the other hand, is a rock formed when limestone recrystallizes into marble during the mountainbuilding process. When rocks are formed, limestone is heated and squeezed which causes the grains to recrystallize. It is metamorphic and is usually used as building material and in sculptures.

Extensive grinding illustrated the intensities from the various mineralogical forms approach a common value by reducing the absorption within the individual particles to a small value (325 mesh). Figure 1 illustrates the relation of intensity with grinding time or a reduction in particle for CaMg carbonate rocks.
Because travertine is a soft stone, it is a difficult choice for flooring and requires special maintenance. Thus, it is most often used for building facades or cladding. It requires grinding to hone the surface, which sometimes reveals deeper holes in the rock, formed by gas bubbles. Limestone, while rugged and durable, scratches and stains easily.
