However, quartzite can also contain small amounts of other minerals, which can affect its color and appearance. These minerals can include:
* Feldspar: Adds a milky or pink hue.
* Mica: Creates a shimmering or sparkly effect.
* Iron Oxides: Gives reddish or brownish tones.
* Hematite: Contributes to a reddish-brown or purple hue.
* Garnet: Adds red or purple speckles.
* Other Trace Minerals: Can contribute to variations in color and texture.
It's important to note that the presence and amount of these accessory minerals can vary greatly depending on the specific quartzite formation. This is why quartzite comes in a wide range of colors, including white, gray, pink, red, brown, and even green.
