Quarrying of Stones: Its Methods, Selection of Site,

No explosive material is used at any stage in this method of quarrying of stones. Soft rocks and also those rocks which have layered structure are easily quarried by these methods. As a first step, the loose cover of soil over the rock (the over-burden) is first removed and the rock surface is cleared.Portland stone - Wikipedia,Portland Stone or Portland Stone Formation is a limestone formation from the Tithonian stage of the Jurassic period quarried on the Isle of Portland, Dorset, England.
