Geology 101: Facts about Marble

20150901_113726Marble is one of the most durable and attractive types of natural stone in the world, which is why it has been used a highly decorative and luxurious materials for floors, walls, facing stones, windowsills, columns, and other building parts since ancient times.

But what is marble actually? And what gives it the qualities that people love about marble?

Manhattan Marble — Geologically Speaking

Marble is technically a non-foliated metamorphic rock that is formed when limestone is exposed to extreme heat and pressure. The rock itself is composed mostly of the mineral calcite, but usually also contains additional minerals, including clays, micas, quartz, pyrite, iron oxides, and graphite.

When all of these minerals are exposed to heat and pressure over time, the calcite in the limestone re-crystalizes, forming a mass of interlocking calcite crystals.

Manhattan Marble — Where Is Marble Found?

Most marble is mined from the ground. It naturally forms large deposits that can be found all over the world, most famously in Italy.

In some cases, these marble deposits can be hundreds of feet thick. Some of the biggest marble quarries have been producing millions of pounds of marble each year for decades.

Marble that is of low quality is typically crushed into dimension stone, which is then used in highways, railroad beds, building foundations, and other structures.

But the best marble — which is identified by its color, hardness, and purity — is sold to businesses around the world, where it eventually makes it way into buildings, homes, statutes, and other places.

Like any luxury stone, marble requires continual maintenance and care in order to maintain its shine and polish.
