Basalt

Basalt is a fine-grained, dark-colored volcanic rock composed primarily of plagioclase, pyroxene, and olivine minerals. It is formed from the rapid cooling of lava at or near the Earth’s surface and is widely used in construction, landscaping, and industrial applications due to its durability and abundance.
SKU: RAW-13

Specifications:
 • Composition:
 • Mainly composed of silica (45-55%), with significant amounts of iron oxide (FeO), magnesium oxide (MgO), and smaller amounts of aluminum oxide (Al2O3)
 • Rich in minerals such as plagioclase feldspar, pyroxenes, and olivine
 • Color: Typically ranges from dark grey to black, with variations in mineral content
 • Texture: Fine-grained, due to the rapid cooling of lava; may appear vesicular (bubbly) or dense
 • Density: Generally between 2.8 to 3.0 g/cm³
 • Hardness: 6-7 on the Mohs scale, making it durable and resistant to wear
 • Porosity: Typically low, contributing to its strength and resilience in various environments
 • Types:
 • Extrusive Basalt: Formed from lava that cools quickly on the Earth’s surface
 • Intrusive Basalt: Forms from magma that cools more slowly below the surface, often referred to as gabbro
 • Applications:
 • Construction: Used in road base material, concrete aggregate, and as crushed stone for building foundations, drainage systems, and landscaping
 • Stone Veneer & Tiles: Cut into slabs and tiles for use in facades, countertops, and flooring
 • Landscaping: Commonly used for decorative features, such as rock gardens, walls, and pathways
 • Railroad Ballast: Used as base material for supporting railroad tracks
 • Refractory Materials: Basalt is used for high-temperature applications due to its resistance to heat
 • Carbon Sequestration: Can be used in environmental efforts to capture carbon dioxide through mineral carbonation processes
