Some granite and limestone deposits are quarried, although the state has many deposits of both. Slate deposits are located near Brownville and Monson in the central part of the state. One of the main elements of the Maine's mining industry is limestone, which is crushed for use in cement. Both Knox and Aroostook counties have limestone quarries. Cumberland and Penobscot counties both produce sandstone, which is crushed for use.
