What causes the minerals to be deposited?
Deposits of minerals form when a medium that contains and transports mineral-making ore releases and deposits the ore. When magma or lava cools, the magma and ore carried within it crystallize to form tiny minerals in the newly-created igneous rock. Minerals found in such rock might include feldspar or mica.
What are the three ways that mineral deposits can form?
The four main categories of mineral formation are: (1) igneous, or magmatic, in which minerals crystallize from a melt, (2) sedimentary, in which minerals are the result of sedimentation, a process whose raw materials are particles from other rocks that have undergone weathering or erosion, (3) metamorphic, in which …

Is gold a mineral deposit?
What is Gold? Native gold is an element and a mineral. Therefore, most gold found in nature is in the form of the native metal. Gold occurs in hydrothermal veins deposited by ascending solutions, as disseminated particles through some sulfide deposits, and in placer deposits.
What are the two types of mineral deposits?
Generally we can classify mineral deposits into two major groups: Industrial and non industrial.
