Placer deposits are natural occurring concentrations of minerals and metals that are found in sedimentary rock formations. These deposits are formed through a series of geological processes that involve the movement, deposition, and alteration of minerals. They are an important source of economic minerals such as gold, silver, copper, lead, and zinc. In

· Heavy minerals are high-density components of siliciclastic sediments. They comprise minerals that have specific gravities greater than the two main framework components of sands and sandstones, quartz (s.g. 2.65) and feldspar (s.g. 2.54–2.76). In practice, heavy minerals are usually considered to be those with specific gravities

2.6: Classes of Minerals. Minerals are classified according to their chemical properties. Except for the native element class, the chemical basis for classifying minerals is the anion, the negatively charged ion that usually shows up at the end of the chemical formula of the mineral. For example, the sulfides are based on the sufur ion, S 2–.
