Using the Fo-An-Q phase diagram below, describe, compare and contrast the liquid lines of descent of two melts (Melt 1 and Melt 2) with the following compositions. Explain the types of textures that may result from these different liquid lines of descent. Be sure to annotate the phase diagram shown below. (11 marks) Melt 1: 70% Fo, 20%An,10%SiO2? Melt2: 80%An,10%SiO2?,10% Fo
