Granite is an intrusive igneous rock, which means that it's formed by magma slowly cooling below the surface of the earth. True granite is a mixture of several different minerals, including quartz, mica, silica, feldspar, and other trace minerals that lend different colors to the stone.

Granite is a kind of igneous rock, found on Earth but nowhere else in the Solar System. It is formed from hot, molten magma.Its colour ranges from pink to grey, according to the proportions of its minerals.. The magma is forced between other layers of rock by the pressure under the Earth's surface.

Fissures naturally occur in granite and add a unique beauty to each stone. Pitting of the surface is also a natural characteristic of granite. Pitting occurs when there are softer minerals contained within the stone that flake at the surface. Pits do not make the granite less durable or inferior.

#2. Granite always contains the same minerals quartz and feldspar, along with a variety of different "accessory" minerals. The quartz and feldspar are responsible for giving granite a lighter hue—hence the abundance of white and pink shades found throughout granite. Darker accessory minerals highlight granite's light background coloring.

Other minerals are biotite or muscovite (between 5% and 15%), and amphiboles. These will make up the colors of the granite, as well as determine the durability of the stone. The amount of the different kinds of mineral you will find in granite depends on the source of the magma from which it came.

The primary minerals making up granite include quartz, feldspars, micas, and sometimes pyroxene, but mostly quartz and feldspar. Because granite often has excess potassium from alkali feldspars, granite is slightly radioactive because radioactive potassium (40 K) is relatively common.

Aug 13, 2018 · Granitoids also have dark minerals, sometimes quite a lot and sometimes hardly any. Usually, feldspar-plus-quartz dominates, and geologists call granitoids felsic rocks in recognition of this. A true granite can be rather dark, but if you ignore the dark minerals and assess only the felsic component, it can still be properly classified.
