Terrazzo flooring containing marble aggregate
Marble (recrystallized calcite, CaCO₃) aggregate in cementitious terrazzo
AI-generated identification · may be incorrectVisible gray and white angular chips in a pale cement binder, with a polished matte-to-satin surface; marble is Mohs 3–4, nonmetallic, commonly calcitic with rhombohedral cleavage. The overall slab is human-processed rather than natural bedrock.

Physical properties
Visible gray and white angular chips in a pale cement binder, with a polished matte-to-satin surface; marble is Mohs 3–4, nonmetallic, commonly calcitic with rhombohedral cleavage. The overall slab is human-processed rather than natural bedrock.
Formation & geological history
Marble forms when limestone recrystallizes during metamorphism, commonly during mountain building; its geological age varies by source. The aggregate was set into cement or terrazzo binder and ground/finished as architectural flooring.
Uses & applications
Used primarily for durable decorative flooring, walls, countertops, and stair surfaces; not generally valued as a collectible geological specimen.
Geological facts
Terrazzo can contain marble, granite, quartz, or glass chips; the irregular chips and continuous binder distinguish it from a natural conglomerate or breccia.
Field identification & locations
Identify by repeated cement-filled joints and uniformly finished surface; acid may weakly fizz on exposed calcite chips, while marble scratches with steel. Common in commercial and residential architecture worldwide.
