Abstract
This chapter presents numerical tools to “revert” the mass-balance relation (of Chap. 6), and explain the composition of a given igneous rock in terms of mixing between different components (solids or liquids). The proportions of each component can be constrained if their compositions are known. Thus it is possible to gain information on, e.g. the proportion of end-members involved in magma mixing, or the percentages of cumulative minerals formed during crystallization.
