Figure 1From: FTIR and Raman spectroscopy characterization of fluorine-bearing titanian clinohumite in antigorite serpentinite and chlorite harzburgitePlot of X F versus X Ti . It shows TiChu’s F-OH exchange reaction follows a compositional vector TiO2Mg-1 F-2. XF is F/(F + OH) in moles. XTi is the fraction of Ti in the Mg-site.Back to article page
