Experimental petrology of oxides to replicate the chemistry of the rock/system in question) in an apparatus capable of creating and sustaining high pressures and temperatures such as a Diamond anvil cell. In general, it is ideal if the enclosing capsule is relatively nonreactive, such as diamond or platinum/gold alloys . Experimental igneous petrology is the subset of experimental petrology concerned with quantifying the behavior of magmas and their associated igneous rocks at depth. Standard procedure generally involves the creation of a synthetic magma (often corresponding to a real world analog) which is then cooled to a target temperature. After crystallization, the products
