    There are three main types of rock sedimentary metamorphic and igneous. They are named by how they are formed. Sedimentary rock forms from sedimentsmall particles of materials such as bits of sand rock and shell. The sediment settles into layers and over a very long period of time eventually hardens into rock making it ideal for forming fossils.

    Intrusive rock is typically very hard and erodes slowly. This allows the surrounding rock to be worn away by wind and water leaving only the harder rock in place. Heavy particles such as gold are likely to accumulate against the harder rock while the lighter materials are more easily moved away.
