Quartzite can appear in many colors.
Air, water, and impurities can change the color of a mineral.
can color be a denitive factor in determinig a mineral
Quartzite
Quartzite is found, amongst other places, in counties Donegal and Wicklow.
Even though it's a blackish/brown mineral, it leaves a WHITE streak.
Quartzite can come in a variety of colors, including white, gray, pink, red, and brown. The color of quartzite is influenced by the minerals present during its formation, resulting in a range of hues.
No, quartzite typically does not have a streak. Streak is a property used to identify minerals by rubbing them on a porcelain plate to see the color of the powder left behind, and quartzite is made up of tightly compacted quartz grains that do not leave a noticeable streak.

Quartzite
Quartzite is a metamorphic rock. It is formed when the mineral quartz is subjected to extreme heat and pressure of the Earth's mantle.
Quartzite comes in a variety of colors including white, cream, grey, pink, red, green, and brown. The colors are typically determined by the mineral impurities present during the formation process.
Quartzite rock is primarily made up of the mineral quartz, which is a hard, abundant mineral composed of silicon and oxygen atoms. Quartzite can also contain other minerals such as feldspar, mica, and iron oxides, but quartz is the dominant mineral in this type of rock.
Quartzite is a metamorphic rock formed from sandstone. The process involves heat and pressure altering the sandstone's mineral composition, causing quartz grains to recrystallize and fuse together, resulting in a harder, more durable rock. Quartzite is known for its smooth texture, high resistance to weathering, and distinctive white color.
Quartzite is mainly composed of quartz, which is a mineral made of silicon and oxygen. It may also contain small amounts of other minerals such as feldspar, mica, and iron oxides. However, the predominant mineral in quartzite is quartz, giving it its characteristic hardness and durability.
Amethyst crystals are a type of quartz mineral that is typically purple in color due to trace amounts of iron in the crystal lattice. They are prized for their vibrant color and are often used for jewelry and decorative purposes.
A pink-ish, brown-ish, red-ish color.
Quartzite contains mostly quartz, which is a very hard and durable mineral that is resistant to weathering. Limestone, on the other hand, is made mostly of calcite, which is more easily dissolved and eroded by acidic water. This difference in mineral composition accounts for quartzite's greater resistance to weathering compared to limestone.
