The process of extraction of suitable stones from their natural rock beds or layers is commonly called Quarrying of Stones.. It differs from the mining of ores of metals in that whereas quarrying is an operation carried out entirely on the surface, mining involves digging below the ground, sometimes at

Quarries are made when big deposits of commercially helpful minerals or rock are found close to the Earth''s surface.
· New quarries, and in particular, ''quarries'' for coal open casting will only receive planning permission if the quarry owner agrees to ''reinstate'' the area back to agricultural use after extraction has finished. This will be a condition of the permission

Sometimes they are also used as leisure lakes – for water sports – although this may conflict with the needs of wetland wildlife.
Some rock units that are stained by iron can be pink, red, or purple. Other impurities can cause quartzite to be yellow, orange, brown, green, or blue.

That same inventory counted 1,367 inactive operations, 70% of which were limestone quarries.
G. W. Bain (1931) has reported the case of flying rocksheets or spalls known as rockbursts in limestone quarries due to spontaneous mechanical rock expansion caused by unloading of superincumbent load. "As new faces are cut in the walls of (limestone) quarries the dense limestone expands, producing cracks parallel to the surface.
Quarrying sites as habitats When extracting minerals, we change nature and the landscape. Our mining activities are handled with most care and take into account the existing biodiversity of the site. Indeed many animals and plants also benefit from our quarrying activities thanks to the large number of different habitats which develop during the quarrying activities.
Whats Happens To The Rocks Of Quarries. Limestone Wikipedia.
