Jurassic Fossil Limestone

Jurassic Fossil Limestone is a distinctive sedimentary rock quarried in the Castellon region of Spain. Renowned for its densely packed, well-preserved fossils of ammonites, shells, corals, and other prehistoric marine life, it offers a window into the ancient marine environments. The stone exhibits a brown color with light golden hues, providing a warm and earthy aesthetic that is sought after in both interior and exterior applications.

Physical and Mechanical Properties

• Water Absorption: Typically ranges between 3-7%, indicating moderate porosity which affects its resistance to weathering and frost.

• Density: Generally falls in the range of 2.35-2.55 g/cm³, depending on the fossil content and specific quarry characteristics.

• Flexural Strength: Usually around 8-12 MPa, making it suitable for various structural applications but requiring careful handling during installation.

• Compressive Strength: Typically between 60-80 MPa, indicating decent load-bearing capabilities for flooring and cladding purposes.

• Hardness: Equivalent to 3-4 on the Mohs scale, suggesting that it is relatively easy to cut and shape but may be susceptible to scratching.

• Porosity: Approximately 8-15%, influencing its weight, insulation properties, and suitability for different environments.

• Slip Resistance: Generally rated medium to high, particularly in finishes designed for external use or wet areas.

Chemical and Mineral Composition (% by weight)

• Calcium Carbonate (CaCO3): 70-85%
• Silica (SiO2): 5-15%
• Iron Oxides (Fe2O3): 2-5%
• Aluminium Oxide (Al2O3): 1-3%
• Clay Minerals: up to 5%
• Organic Material: Trace amounts, accounting for color variations and fossil content

Usage

• Interior Flooring: With its aesthetic appeal and adequate strength, it is suited for living spaces, hallways, and bathrooms.
• Exterior Cladding: Resilient to weathering, making it ideal for facades and external walls.
• Countertops: Provides a unique appearance, although requires proper sealing.
• Monumental and Sculptural Works: Its fossil patterns make it popular for artistic and commemorative purposes.

Maintenance

• Sealing: Regularly seal to protect against staining and water ingress, particularly in high-traffic or wet areas.
• Cleaning: Use pH-neutral cleaners to avoid damaging the surface. Avoid acidic or abrasive substances.
• Polishing: May require periodic polishing to maintain a glossy finish, depending on the surface finish.

Cutting Sizes (cm)

• Standard tiles: 30x30, 40x40, or 60x60
• Slabs: Typically 2 or 3 cm in thickness, various custom dimensions available.

Common Surface Finish Options

• Polished: Offers a glossy, reflective surface that highlights fossil details but is more slippery.
• Honed: A matte, smooth surface that balances beauty and slip resistance.
• Brushed: Provides a slightly textured surface, adding slip resistance and a rustic appearance.
• Bush-Hammered: A rough finish that enhances slip resistance, often used for exterior applications.
• Antiqued: Gives an aged appearance with subtle texture variations.

In summary, Jurassic Fossil Limestone offers a unique combination of aesthetic and functional properties that make it suitable for a range of architectural and decorative applications, provided that its maintenance needs are carefully managed.
