Whois & Analysis for stonecontact.com

Travertine is a form of limestone deposited by mineral springs, especially hot springs.

Travertine often has a fibrous or concentric appearance and exists in white, tan, cream-colored, and even rusty varieties.

It is formed by a process of rapid precipitation of calcium carbonate, often at the mouth of a hot spring or in a limestone cave.

In the latter, it can form stalactites, stalagmites, and other speleothems.

It is frequently used in Italy and elsewhere as a building material.

Limestone is a sedimentary rock, composed mainly of skeletal fragments of marine organisms such as coral, forams and molluscs.

Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3).

Granite is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture.

Granites can be predominantly white, pink, or gray in color, depending on their mineralogy.

The word "granite" comes from the Latin granum, a grain, in reference to the coarse-grained structure of such a holocrystalline rock.

By definition, granite is an igneous rock with at least 20% quartz and up to 65% alkali feldspar by volume.

Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism.

It is the finest grained foliated metamorphic rock.

Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression.

Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite.

Marble may be foliated.

Geologists use the term "marble" to refer to metamorphosed limestone; however, stonemasons use the term more broadly to encompass unmetamorphosed limestone.

Marble is commonly used for sculpture and as a building material.
