Non-Metallic Deposits
Examples of non-metallic rocks and minerals of economic interest include coal, gemstones, construction aggregate (gravel or riprap), building stone, salt, gypsum and anhydrite, industrial-grade clays, fluorspar, phosphate, nitrate, and barite. Peat moss is included here because it is a fossil resource (i.e., it is mined faster than it is formed) similar in many respects to coal.

Peat Moss in Nova Scotia
Peat is the partially decomposed remains of plants and animals which have accumulated in oxygen poor freshwater environments over the past 11 000-13 000 years. Peat is mined for horticultural purposes, and is also used in distillation, yeast cultivation, as an energy source, and in manufacture of ferrosilicons.
