Both strong and durable, Meteor Stone's ESPERANCE PINK GRANITE features a black flecked matrix, that's speckled with a white and pink quartz. KIMBERLEY BLACK GRANITE naturally varies in colour from charcoal grey to deep black.
Allan Fox writes, in the Steve Parish Publishing book, amazing facts about Australian Landforms: The term 'granite' defines a group of related stones, all of which have their origin deep in the earth's molten mantle.
Large amounts of rising molten rock do not reach the surface but instead begin to slowly cool and harden, kilometres under the Earth's surface. This forms a batholith, a large body of igneous rock, shaped like a great hot-air balloon. For millions of years they cool and during this time the three main kinds of minerals of granite (silica, mica and feldspar) collect into crystals. Silica is glass-like. The colour of granite comes from the mix that makes the mica and the feldspar.
While a batholith is cooling, vapours and solutions of rare minerals that do not fit into the crystal structure of the three main components leak into surrounding rock. Minerals such as gold, silver, copper, lead and zinc fill cracks and rifts caused by the rising batholith, becoming veins or massive ore bodies.
Kilometres above, as the surface is constantly eroded, the land mass rises. After perhaps 50 or 100 million years, the crown of the batholith appears on the surface. In some places where the Earth's crust is under pressure, it begins to fault and fold, and the granite mass is uplifted.
Weathering and erosion penetrate joints isolating some of the layers of huge blocks. These are then rounded off by weathering to stand as tors. In some places, whole mountains are rounded to gigantic tors because of the uniform mix of crystals in the granite.
"Granite is slip resistant, withstands harsh weather and pollution, is colourfast and complements the natural environment."
