What Metamorphic Rock Is Formed From Sandstone? Quartzite, a durable and visually appealing stone, is formed from sandstone through metamorphism, and at rockscapes.net, we help you explore the beauty and possibilities of using quartzite in your landscape design. Our expert guidance ensures you can select the perfect stones to enhance your outdoor spaces with natural elegance and longevity.
1. Understanding Metamorphic Rock Formation
Metamorphic rocks are created when existing rocks, such as sedimentary or igneous rocks, are transformed by heat, pressure, or chemically active fluids. This process, called metamorphism, changes the mineral composition, texture, and sometimes even the chemical composition of the original rock.
1.1. The Metamorphic Process
The metamorphic process occurs deep within the Earth’s crust where temperatures and pressures are significantly higher than at the surface. According to research from Arizona State University’s School of Earth and Space Exploration, high temperatures can cause minerals to recrystallize, while high pressure can cause them to align in a specific direction. Chemically active fluids can introduce new elements or remove existing ones, further altering the rock’s composition.
1.2. Types of Metamorphism
There are two main types of metamorphism:
- Regional Metamorphism: This occurs over large areas and is associated with mountain-building events. It results from the intense pressure and heat generated by the collision of tectonic plates.
- Contact Metamorphism: This occurs when magma intrudes into existing rock. The heat from the magma alters the surrounding rock, creating a zone of metamorphic rock around the intrusion.

2. Sandstone: The Parent Rock
Sandstone is a sedimentary rock composed primarily of sand-sized grains of mineral, rock, or organic material. It’s a common rock type that can be found in various environments around the world.
2.1. Composition of Sandstone
The most common mineral in sandstone is quartz, but it can also contain feldspar, mica, and various other minerals. The grains are typically cemented together by silica, calcium carbonate, or iron oxide.
2.2. Types of Sandstone
There are several types of sandstone, classified based on their mineral composition and texture. Some common types include:
- Quartz Arenite: Composed almost entirely of quartz grains.
- Arkose: Contains a significant amount of feldspar grains.
- Greywacke: A poorly sorted sandstone containing a mixture of sand, silt, and clay-sized particles.
2.3. Uses of Sandstone
Sandstone has been used for centuries as a building material. Its durability and attractive appearance make it a popular choice for walls, paving stones, and decorative features. According to the United States Geological Survey, sandstone is also used in the manufacture of glass and ceramics.
3. Quartzite: The Metamorphic Transformation of Sandstone
Quartzite is a metamorphic rock formed when sandstone is subjected to high temperatures and pressures. This process causes the quartz grains in the sandstone to recrystallize, creating a dense, hard rock.
3.1. The Formation of Quartzite
During metamorphism, the individual quartz grains in sandstone fuse together, forming an interlocking network. This process eliminates the pore spaces that are present in sandstone, making quartzite much harder and more resistant to weathering.
3.2. Characteristics of Quartzite
Quartzite is characterized by its hardness, durability, and crystalline appearance. It typically has a light color, ranging from white to gray, but can also be pink, red, or brown depending on the presence of impurities.
| Characteristic | Quartzite | Sandstone |
|---|---|---|
| Hardness | Very hard, difficult to scratch | Relatively soft, can be scratched easily |
| Texture | Crystalline, interlocking grains | Granular, individual grains visible |
| Porosity | Low, almost non-porous | High, porous |
| Composition | Primarily quartz | Primarily quartz, but can contain other minerals |
| Formation | Metamorphism of sandstone | Sedimentation and cementation of sand grains |
| Uses | Countertops, paving stones, decorative aggregate | Building stone, paving stones, aggregate |
| Color | White, gray, pink, red, brown | Varies depending on mineral composition, typically light brown, tan, or red |
| Weathering | Highly resistant to weathering | Less resistant to weathering |
| Fracture | Fractures across grains | Grains break apart |
| Grain Size | Fine to medium | Fine to coarse |
| Density | High | Low to medium |
| Luster | Vitreous | Dull |
| Appearance | Glassy, crystalline | Earthy, granular |
| Notable Types | Rose Quartzite, Milky Quartzite | Arkose, Quartz Arenite |
| Common Regions | Brazil, South Dakota, parts of India | Worldwide, including the Colorado Plateau, and various coastal and desert regions |
| Applications | High-end architectural designs, durable outdoor surfaces, decorative landscaping, kitchen countertops in luxury homes | General construction, historical buildings, garden pathways, used in cement and asphalt mixes |
| Maintenance | Low; requires infrequent sealing to prevent staining | Moderate; may require regular sealing, especially in wet climates, to prevent erosion and maintain structural integrity |
| Cost | Higher due to processing and durability | Generally less expensive |
| Environmental | Quarrying can impact landscapes; sourcing from sustainable quarries is preferable | Extraction can lead to habitat disruption; responsible sourcing mitigates environmental impact |
| Heat Resistance | Excellent, making it suitable for fireplaces and outdoor kitchens | Less heat resistant; prolonged exposure to high temperatures can cause cracking |
| Slip Resistance | Can be textured to provide a non-slip surface, ideal for pool decks and patios | Varies; smoother surfaces can be slippery when wet |
| Cutting | Requires specialized tools due to its hardness | Easier to cut and shape |
| Joining | Mortar or epoxy adhesives | Mortar |
| Popularity | Increasing in popularity due to its aesthetic appeal and longevity | Remains a staple in construction and landscaping |
| Installation | Requires skilled labor for precise fitting | Can be installed by DIY enthusiasts for simpler projects |
| Weight | Heavier than sandstone | Lighter, making it easier to handle |
3.3. Identifying Quartzite
One way to distinguish quartzite from sandstone is to break the rock. Sandstone will typically break along the grain boundaries, while quartzite will fracture across the grains. According to the Geological Society of America, quartzite is also much harder than sandstone and will scratch glass.
