Use of olivine and plagioclase saturation surfaces for the petrogenetic modeling of recrystallized basic plutonic systems [PDF]

During petrogenetic studies of basic plutonic rocks, there are at least three major questions to be considered: (1) what were the relative proportions of cumulate crystals and intercumulus melt in a given sample? (2) what is the composition and variation
