Sand and Gravel. Sand and gravel deposits found on beaches or in rivers and streams, are mostly quartz (silicon dioxide, SiO 2) grains. Weathering of rocks such as granite forms these quartz grains. In the process of weathering, the softer, weaker minerals in granite (such as feldspar) are weathered away.
Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an orebody, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Iron ore can be defined on the basis of its iron content into low-grade ore (taconite), which commonly contains 25 to 35% iron, and high-grade ore, which contains 50 to 70% iron. Iron-bearing ore minerals include oxides, carbonates, silicates, and, in some cases, sulfides.
Gold in its natural mineral form almost always has traces of silver, and may also contain traces of copper and iron. A Gold nugget is usually 70 to 95 percent gold, and the remainder mostly silver. The color of pure Gold is bright golden yellow, but the greater the silver content, the whiter its color is.

Rocks and minerals are important for learning about earth materials, structure, and systems. Studying these natural objects incorporates an understanding of earth science, chemistry, physics, and math. The learner can walk away with an understanding of crystal geometry, the ability to visualize 3-D objects, or knowing rates of crystallization.
