Part B:Tying plutonic igneous textures to their ternary phase diagram-in both directions! rock 1) Starting with a known composition of magma, plot the magma evolution path during slow cooling/crystallization and predict what the rocks texture will be for the following mafic magma composition: 50% Anorthite, 30% Diopside, 20\% Forsterite A) Plot the magma composition as point M, then show the path of evolving liquid composition during crystallization. B) Describe in your own words what the plutonic rock texture will look like. 2) Now starting with the following plutonic rock texture, determine the crystallization history of this rock. A rock consists of 10% euhedral phenocrysts of Anorthite, 20% as a mix of subhedral crystals of An and Fo with proportions of 70% An and 30% Fo, and a groundmass of anhedral crystals that make up 70% of the rock. The groundmass consists of 50% Di, 43% An, and 7% Fo. A) Plot the original magma composition as Xb, B) Trace the path of the evolving solid composition during crystallization. Anorthite 1553.
