By combining the mass balance (Chap. 6) and partition coefficient (Chap. 10) concepts, it is possible to derive a range of laws that relate the trace-element composition of a melt to that of its source, the nature and proportion of solid phases (cumulate or restite), etc. Various laws are written to account for different situations (melting, crystallization, mixing; batch or fractional; etc.).
