'The creation of magma in subduction requires the addition of water the source of which comes from minerals in the down-going ocean crust.
In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid compound with a fairly well-defined chemical composition and specific crystal structure that occurs naturally in its pure form.[1][ 2]
Geological definitions of minerals generally exclude compounds that are unique to living organisms. However, some minerals are often biogenic (such as calcite) or organic compounds in the chemical sense (such as melite). Additionally, organisms often synthesize inorganic minerals (eg, hydroxyapatite) that are also found in rocks.
The term "mineral" is different from rock. Rocks are solid bulk geological materials that are relatively homogeneous on sufficiently large scales.
