Type of stone

Origin of stone: INDIA

Marble:

The word marble derives from the Greek marmaros that means “SHINING STONE”. Pure marble colour is white it shows absent of the any kind of impurities. The resulting marble rock is typically composed by nature of an interlocking mosaic of carbonate crystals rocks either limestone or dolostone. Primary sedimentary textures and structures of the original carbonate rock (protolith) have typically been modified.

The temperatures and pressures are necessary to form marble usually destroy any fossils & sedimentary textures present in the original rock. The characteristic swirls and veins of several colored marble varieties are usually due to various mineral impurities such as clay, silt, sand, iron oxides, or chert which were originally present as grains or layers in the limestone. These lots of impurities have been mobilized and re-crystallized by the intense pressure and heat of the metamorphism.

Granite:

The word granite derives from the Latin word granum, a grain, in reference to the coarse-grained structure of such a crystalline rock. Granite stone is an igneous rock with at least 20-25% quartz (i.e. the percentage of the rock made up of dark minerals) by volume. Granite differs from granodiorite in that at least 34% of the feldspar in granite is alkali feldspar as opposed to plagioclase; it is the alkali feldspar that provides many granites a distinctive pink color.

Granite is nearly always massive (lacking internal structures), hard and tough, and therefore it has gained widespread use as a construction (Flooring & Countertop) stone. Its compressive strength usually lies above 200 MPa, The average density of granite is located between 2.65 and 2.76 G/cm3, Melting temperature is 1215 – 1250 °C. The most part in granite is SiO2 — 72.04% (silica)

Slate:

The word slate derives from the French verb escalator meaning “to split”. Slate is waterproof, chemically resistant and non-combustible Slate which is composed of muscovite and quartz or illite, mica, often along with hematite, chlorite, biotite & pyrite and less frequently, kaolin, tourmaline, apatite, graphite, magnetite or zircon as well as feldspar. Fine-grained metamorphic rock that splits into thin more than two layers, smooth-surfaced layers. Slate is basically mudstone or sediment that had previously formed on ocean floors and was subject to intense heat and unimaginable pressure approximately 350 to 554 million years ago when the earth was an extremely volatile planet.

Slate is mainly suitable as a roofing material especially rainy area as it has an extremely low water absorption index of less than 0.4%. Its low tendency to absorb water also makes it very resistant to frost damage and breakage due to freezing. One of important application of slate is using as Blackboard Black in colour makes it as educational tools.

Limestone:

Limestone, it is a kind of sedimentary stone that is quite common all over the Europe and Mediterranean. Limestone is deposit of the shells of zillions of little sea snails and creatures like that. These snails, creatures and stuff lived in the sea, thousands to millions of years ago, and when they died they fell & remained at the bottom of the sea and rotted, but their shells, which were made of calcium like your bone & teeth, did not rot and just stayed there. Pressure from other shells, and from the water, and from sand being washed over the shells, squashed them all together into rock.
