Limestone
Limestone is a sedimentary rock composed mostly of the mineral calcite and makes up about 15% of the Earth’s sedimentary crust. Limestone is formed when the area gets covered with warm, shallow marine water. Many people mine limestone from a quarry.
Uses: Primarily used in construction projects – for concrete, asphalt, cement, bridges, agriculture and parking lots.
Color: Limestone is typically grey in color, it can be a light grey or a dark grey.
Fun fact! Did you know? The world’s largest limestone quarry is located in northern Michigan, near Rogers City.
