Origin of granite there are two theories for the origin of granite. The magmatic theory states that granite is derived by the crystal fractionation of magma. Thus granite bodies are the result of intrusion of liquid magma into the existing rocks. The granitization theory states that granite is formed in place by extreme metamorphism. There is evidence to support both theories, and both are useful to explain different observed features. The two may actually merge: as metamorphic conditions increase to the melting point of the metamorphosed granite, it will melt and become a liquid magma. Uses of granite granite has been extensively used a dimension stone and as flooring tiles in public and commercial buildings and monuments.

What is marble? marble is metamorphosed limestone, composed of fairly pure calcite (a crystalline form of calcium carbonate, caco3). It is extensively used for sculpture, as an building material, and in many other applications. Origins of marble marble is a metamorphic rock resulting from regional or at times contact metamorphism of sedimentary carbonate rocks, either limestone or dolostone. This metamorphic process causes a complete recrystallization of the original rock into an interlocking mosaic of calcite andor dolomite crystals. The temperatures and pressures necessary to form marble usually destroy any fossils and sedimentary textures present in the original rock. Pure white marble is the result of metamorphism of very pure limestones. The characteristic swirls and veins of many 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. Green coloration is often due to serpentine resulting from originally high magnesium limestone or dolostone with silica impurities. These various impurities have been mobilized and recrystallized by the intense pressure and heat of the metamorphism.

Limestone is a sedimentary rock composed of the mineral calcite (calcium carbonate) . The primary source of this calcite is usually marine organisms. These organisms secrete shells that settle out of the water column and are deposited on ocean floors as pelagic ooze (see lysocline for information on calcite dissolution). Secondary calcite may also be deposited by supersaturated meteoric waters (groundwater that precipitates the material in caves). This produces speleothems such as stalagmites and stalactites. Limestone makes up approximately 10 percent of the total volume of all sedimentary rocks.

Quartzite is a hard, metamorphic rock which was originally sandstone. Through heating and pressure usually related to tectonic compression within orogenic belts, the original quartz sand grains and quartz silica cement were fused into one. Pure quartzite is usually white to grey. Quartzites often occur in various shades of pink and red due to varying amounts of iron oxide. Other colors are due to impurities of minor amounts of other minerals. Quartzite is a hard, metamorphic rock which was originally sandstone.

We are offering origins of sandstone sandstones are clastic in origin (as opposed to organic, like chalk or coal). They are formed from the cemented grains that may be fragments of a pre-existing rock, or else just mono-minerallic crystals. The cements binding these grains together are typically calcite, clays and silica. Grain sizes in sands are in the range of 0.1mm to 2mm. (rocks with smaller grainsizes include siltstones and shales and are typically called argillaceous sediments, as are also clays. Rocks with larger grainsizes include both breccias and conglomerates and are termed rudaceous sediments.). The principle mechanism for the formation of sandstone is by the sedimentation of grains out of a fluid, such as a river, lake or sea. The environment of deposition is crucial in determining the characteristics of the resulting sandstone, which on a finer scale include its grainsize, sorting, composition and on a larger scale include the rock geometry. Principal environments of deposition may be split between terrestrial and marine, as illustrated by the following broad groupings: terrestrial environments1. Rivers (levees, point bars, channel sands)2. Lakes marine environments1. Shoreface sands2. Deltas3. Turbidites (submarine channels)

Slate is a fine-grained homogeneous sedimentary rock composed of clay or volcanic ash which has been metamorphosed (foliated) in layers (bedded deposits). Slate can be made into roofing shingles ('roofing slates' in the uk ) because it has two lines of breakability: cleavage and grain. This makes it possible to split slate into thin sheets.

When choosing roofing materials, one must take into consideration the longevity of the roofing material, as well as the installation cost. Slate roofs have been known to last hundreds of years in comparison to the synthetic roof which typically lasts 10-20 years. Synthetic and manufactured roofing materials may initially save money at the time of installation, but the slate roof will last many lifetimes, making it the more permanent, economical choice.

We are offering fireplaces.Marble, granite and stone fireplaces have been the heart of the british household for centuries, providing warmth, light and also a beautiful focal point and beautiful creation for any room. Today, chariot international can offer fireplaces to suite any style or colour scheme from traditional to contemporary. The stone hearths are easy to keep clean and can be used with wood fires, electric fires and gas fires. With marble fireplaces, you can choose a variety of granites and marbles colors and designs. A fireplace made with marble can be come in one piece and makes this seamless and easy to install in any home. Stone fireplaces are common in older and newer homes. The size of your fireboxes will determine the size of the fireplace you need. Your firebox is the inside where the fire will be burning. Older stone fireplaces where not installed with doors, but with screens. You can build your fireplace with or with out doors.
