Stonyfell Quartzite is a durable, metamorphic rock primarily composed of quartz. It is characterized by its hard texture and often displays a range of colors, including gray, pink, and white. This rock is commonly found in the Adelaide Hills region of South Australia and is known for its resistance to weathering, making it a popular choice for construction and landscaping. The formation of Stonyfell Quartzite dates back to the late Cambrian period, around 500 million years ago. It originated from sandstone that underwent metamorphism due to heat and pressure over millions of years. Today, it is frequently used in building materials, paving, and decorative stone applications.
