The Ti-saturation surface for low-to-medium pressure metapelitic biotites: Implications for geothermometry and Ti-substitution mechanisms

DJ Henry, CV Guidotti, JA Thomson - American mineralogist, 2005 - degruyter.com
The Ti content of biotite can serve as a geothermometer for graphitic, peraluminous
metapelites that contain ilmenite or rutile and have equilibrated at roughly 4-6 kbar. The …
