Quarry

A quarry is a type of open-pit mine from which rock or minerals are extracted. Quarries are generally used for extracting building materials, such as dimension stone. Quarries are usually shallower than other types of open-pit mines.

People in some English-speaking countries are unlikely to make the distinction between this type of mine and any other type of open-pit or open-cast borrow or gravel pit mining operation.

Minerals extracted from quarries include:

• Cinder
• Coquina
• Blue rock
• Granite
• Gritstone
• Limestone
• Marble
• Sandstone
• Slate
