Pelusa Orellana García,Paula Baldwin Lindyolite and fluorite show minor endothermic effects caused by structural changes (see Fig. 10). The cryolite is a suitable internal standard for the determination of the high-low inversion temperatures of quartz crystals (see III-8), because of its reversible structural transformation temperature of
