Granite is one of the most common igneous rocks found on the earth’s surface. With light and dark-coloured tones, granules are large enough to recognize minerals without a magnifying glass. Igneous rocks form through the volcanic process of rock having solidified from magma or lava.
Comprising granite is an abundant amount of quartz and feldspar. Minor traces of other minerals can sometimes be in granite, including amphiboles (a mineral typically forming as prismatic or needle-like crystals). Granite is defined depending on the industry. Complexities occur when giving an igneous rock a formal name due to its composition. Granite uses unique titles determined by grain size. There are many names for specific types of granite which are, defined by the aggregate and texture.
Often extracted from quarries and desired for its properties as a “dimension stone,” granite can withstand wear from rubbing, is capable of supporting large weights, naturally prevents deterioration, and has a nice finish when polished.
An effective way to identify, study and examine minerals constituting igneous rocks. Ideal for classrooms, rock discussions, and classification. Applications include borders around homes, decorative garden stones, pool accents, ponds and water features.
