Stone Veneer Ledgestone

Stone Veneer Ledgestone: Definition & Classification

Definition

Stone veneer ledgestone refers to natural stone that requires polishing and exhibits wide variations in composition and structure. These stones range from pure carbonate rocks to low-carbonate rocks and are commercially classified as marble. Most of them feature patterns or veins, and their crystal grain size varies from cryptocrystalline to 5mm in diameter.

1. Calcite Marble

• Composition: Primarily calcite
• Characteristics: Crystallized due to recrystallization

2. Dolomite Marble

• Composition: Mainly dolomite
• Formation: Developed under high temperature and high pressure during the metamorphic process

3. Serpentine Marble

• Composition: Serpentine (magnesium silicate hydrate)
• Appearance: Green or dark green with veins of dolomite, calcite, or magnesite

4. Tuff Marble

• Composition: Tuff with a porous, layered structure
• Special Feature: Contains calcite crystals

• Color: Ranges from pink to light gray or dark gray
• Composition: Mainly quartz and feldspar, with minor amounts of black minerals
• Texture: Uniform grain texture, sometimes appearing in gneiss or porphyry structures

• Composition: Mainly consists of minerals and rock particles (0.06-2mm in size)
• Silica Content: More than 60% silica
• Structure: Porous, formed by agglomeration of silica, iron oxide, carbonate, or clay

1. Blue-Lime Sandstone & Brown Sandstone

• Silica Content: 60-90%

2. Ortho-Quartz Sandstone

• Silica Content: 90-95%

3. Quartzite

• Silica Content: Above 95%

By understanding these classifications and compositions, you can better select the appropriate stone veneer ledgestone for different applications.
