Sandstone (Navajo Sandstone)
Utah Red Sandstone
Utah Red Sandstone, often referred to as Navajo Sandstone, is a prominent geological formation in Utah, known for its striking red and orange hues. It is a Jurassic-aged aeolian (wind-deposited) sandstone, characterized by large-scale cross-bedding, indicating ancient desert environments. The red color is due to iron oxides within the quartz grains. It is a durable and aesthetically pleasing stone.
- Origin
- Utah, USA
- Quarry
- Southern Utah (historically quarried in areas like Zion National Park, though active commercial quarrying for dimension stone is limited).
- Mohs hardness
- 6-7
- Water absorption
- Low to moderate (Sandstone typically has low to moderate water absorption, requiring sealing for exterior use).
- ASTM spec
- Sandstone typically falls under ASTM C616 (Standard Specification for Quartz-Arenite Dimension Stone). Specific ASTM data for Utah Red Sandstone is not readily available in snippets, but general sandstone properties apply.
- Installed price
- $15 - $40 (General sandstone veneer installed can range from $20-$40/sq ft. Flagstone patios installed can be $15-$30/sq ft. Pricing varies based on thickness, cut, and application).
- Slab price
- $3 - $10 (Material cost for flagstone can range from $3-$10/sq ft depending on thickness and type. Specific slab pricing is not readily available, as it's often sold as cut stone, veneer, or flagstone).
- Finishes
- Natural Cleft, Sawn, Split Face, Tumbled
- Applications
- Building veneer, retaining walls, patios, walkways, landscaping, fireplaces, interior and exterior applications.
- USA distributors
- Utah Stone, Western Stone & Materials, various landscape suppliers in Utah and the Southwest.
