Granite is formed from magma which has found
its way through the earth’s crust and solidified. It is generally
accepted that most granites were formed during the Carboniferous
and Permian geological ages some 250-360 million years ago.
In many cases the granite was not exposed until millions of years
later when the overlaying softer soils and rocks had been eroded
away.
The colour and appearance of granite can vary enormously, as shown
by our range. If the molten magma was close to the surface cooling
would have been rapid thus resulting in a fine texture, e.g. SPI,
however if the deposits were deeper set, the rate of cooling would
be considerably slower, therefore enabling larger crystals to form,
e.g. Baltic Brown.
By using the word “granite” we refer to compact polishable
igneous rocks that are suitable for building and decorative purposes,
consisting of minerals such as silica, feldspar, engine, mica, basalt,
diorites etc.
Granite is quarried extensively throughout the world and its resilience,
strength and high aesthetic value as well as its ability to be polished
into various textures makes granite unique as a quality building
material. |
