TOURMALINE: AN IDEAL INDICATOR OF ITS HOST ENVIRONMENT

Journal article

Tourmaline-supergroup minerals are ubiquitous accessory minerals in rocks of the Earth's crust. They can adjust their composition to suit a wide variety of environments, and therefore display a remarkable range in stability in terms of pressure, temperature, fluid composition, and host-rock composition. Because of this compositional sensitivity, tourmaline is an excellent indicator of the environmental conditions in its host. This is further enhanced by negligible diffusion up to high tempera...
