Where does granite come from?
Where to begin? Most accurate articles about
rock are written by geologists. They quickly
become boring and confusing. The subject is
so complex that everybody gets confused -
and that's OK.
So where do we start? Well, lets try and start
at the beginning. Now any discussion regarding
granite is kind of like walking into a movie half way through. It
has literally taken "Billions" of years to form.
So what is granite? Granite is an "Igneous" rock that was formed
from molten lava. Granite owes its hardness to two major players.
First, being solidified deep with in the earths crust. Second, being
cooled very slowly - overs millions of years. As the crust of our
planet has changed , these massive deposits slowly made their
way towards the earths surface. These deposits have been found
on all continents.
While commercially, we consider all granites, well granite - it is
not true. Just because it is sold as granite does not make it granite!
The main minerals in a true granite are Silicates, Feldspar, and
quartz. A TRUE granite is usually easy to distinguish because of its
lighter colors. Approximately 98% of the stone sold as granite are
not granite! They can be a Norite (Black Galaxy), a dolerite (Black
Zimbabwe), a larvikite (Blue Pearl), a anorthiste (Volga Blue), a
gneiss (Santa Cecelia), or a Charnockite (Verde Ubutuba) - these
are just to name a few. . That doesn't mean that they are not as
good as true geological granite. As a matter of fact, some of them
are better than a true granite.
So how did these mineral deposits end up
as the shiny, beautiful counter tops in
your kitchen? Well they certainly did not come
from your local Home Depot. They started there
journey in perhaps as far away as Brazil, Italy,
Africa, Russia, Norway, or India. Or maybe
these beautiful stones came from as close as
New Hampshire, Maine, Virginia, North Dakota,
or North Carolina.
The stone was removed from the earth, using
various methods, in large cubic blocks. From
there, they are trucked to a sawing facility.
Using a water jet cutting system or a wire
saw, the blocks are sawn down into shippable
pieces called slabs. From there the slabs are
shipped by container to distributors and
fabricators all over the world. This is where you come in!
We love stone - that's all we can say. If we can be of any service to
you, please let us know. We're always glad to answer questions and
help you make a decision that's best for you. If you're reading this
than chances are you are strongly considering natural stone in some
form. I say - you will not be disappointed.
