Major Minerals:
* Quartz: A hard, glassy mineral that gives granite its characteristic sparkle. It's typically white or gray but can be other colors.
* Feldspar: This group of minerals is responsible for the pink, red, or white colors often seen in granite. There are two main types:
* Orthoclase (Potassium Feldspar): Gives a pinkish or red color.
* Plagioclase (Sodium-Calcium Feldspar): Gives a white or grayish color.
* Micas: These minerals give granite its sheen and are often visible as small, dark flakes. There are two types:
* Biotite: Black or dark brown.
* Muscovite: Silver or white.
Minor Minerals:
* Amphibole: A dark, elongated mineral that can be found in some granites.
* Pyroxene: Another dark mineral that can be present in small amounts.
* Iron Oxides: These minerals contribute to the red, brown, or yellowish colors sometimes seen in granite.
Accessory Minerals:
* Zircon: A small, hard mineral that can be found in trace amounts.
* Apatite: A phosphate mineral that is often found in small quantities.
* Others: Rare minerals can also be present in trace amounts.
Note: The specific minerals present and their proportions can vary depending on the location and formation of the granite. This is why you see so much variety in the colors and patterns of granite.
