Quarrying is the process of removing rock, sand, gravel or other minerals from the ground in order to use them to produce materials for construction or other uses. So, a quarry is any such working on the surface of the earth where minerals are extracted. Quarries are also known by other names around the world: 'surface mine', 'pit', 'open ...
5 – The Market for Stones. The rapid expansion of Rome during its Late Republic put a large demand on quarrying stones for building materials and decoration. Romans saw stone buildings as a proper way of building, following the Greeks (Russell, 2013). Decorating these buildings with marble and granite was costly.
