Granite (Igneous Rock)
|
| Igneous rocks are formed from the solidification of magma deep in the earth. They contain 45 to 66% silica (Quartz). The remaining minerals are mostly feldspar, mica and iron ores. Granite is the most abundant igneous rock found on earth. |
Marble & Slate (Metamorphic Rocks)
|
| Metamorphic rocks are limestones that have been exposed to high temperatures and high pressures over a long period of time. The change is known as metamorphosis and hence the name metamorphic. The change causes the minerals to go through a molten phase. For this reason marble often has distinct swirls or bands. |
Quartzite (Metamorphic Rock)
|
| Quartzite is also a rare flooring material but is gaining popularity. It is metamorphosed quartz sand and is classified as sandstone. For this reason it exhibits all properties under the sandstone category. |
Limestone & Sandstones (Sedimentary Rocks)
|
| Sedimentary rocks are simply produced from erosion of the other rocks as well as compression and underground water erosion(Lithification). The sedimentary group of rocks cover nearly 75% of the earths surface. For our purposes sedimentary rocks can be classified into two types: Limestones and Sandstones. |
Terrazzo
|
| Terrazzo is a type of concrete in which chips or pieces of the stone (usually marble) are mixed with cement then ground to a flat surface exposing the chips which take a high polish. |
Travertine Marble
|
| A variety of limestone regarded as product of chemical precipitation from hot springs. Travertine is cellular with the cells usually concentrated in thin layers that display a stalactite-like structure. Some that take a polish are sold as marble and may be classified as travertine under the class of "Commercial Marble". |
