Quartz, Silicon Dioxide:
One of the most common minerals found in the Earth’s crust. If pure, quartz forms colourless, transparent and very hard crystals with a glass-like luster. Quartz is a significant component of many igneous, metamorphic and sedimentary rocks. Silicon dioxide is found in a wide range of varieties and colours. Quartz in its polished form, was the most advanced technology thousands of years ago.
A major ore of copper. Common in sulfide veins and disseminated in igneous rocks.
Weathering may lead to the formation of malachite, azurite, brochantite, langite and numerous other secondary copper minerals.
