		Granite is an intrusive igneous rock, it’s characteristic grainy structure and strength is the result of many individual crystalline structures which form tightly together as magma slowly cools within large, deeply buried rock bodies known as plutons. The first step in quarrying is to remove the layer of earth, vegetation, and rock. After the face of the granite is exposed, the stone is removed from the quarry in benches, usually 8 to 12 feet square extending 20 feet or more. Heavy equipment is used to lift the granite bench and transfer it to an inspection area for grading.
		Transportation of the (raw) stone is then made from the quarry to the processing facility, and the stone may be transferred to distribution locations worldwide. Additionally, some granite (blocks) may have been cut into slabs before reaching the main fabrication plant. These are most commonly sliced to a thickness of 3/4 in (2 cm) or 1-1/4 in (3 cm) in lengths of approximately 8-10 ft and widths around 3-5 ft. Processing operations include much more variation than extraction. The general procedure begins with initial cutting, followed by application of a finish, and conclude with a second cutting or shaping step.
