About Titanclinohumite
Formula:
Mg9(SiO4)4(F,OH)2
Lustre:
Vitreous
Hardness:
6
Crystal System:
Monoclinic
A Ti-bearing variety of both Clinohumite and Hydroxylclinohumite.
The varietal name titanoclinohumite (older literature uses the name "titanolivine" for this variety) is commonly used to indicate Ti-bearing hydroxylclinohumite found in metamorphosed serpentinites. Zambonini (1919) came to the conclusion that "titanolivine" from Ala Valley (Piedmont, Italy) is a titanian clinohumite very rich in OH and pratically F-free; therefore, he proposed, unsuccessfully, to substitute the name "titanolivine" with "titanhydroclinohumite" or "hydroclinohumite titanifère" (the species hydroxylclinohumite has been instituted in 1998 only).
