Message to Andreas Tennie,
I have additional information for you but cannot reach you by e-mail.

>experimental calibration of the isotope fractionation of the alumosilicates
>kyanite, sillimanite and andalusite. The experiments are finished for the
>most part and now I want to applicate the results to natural mineral
>assemblages. Although I have already a selection of samples I am searching

>(1980) and Sharp et al. (1993). Any advice, help or comment is greatly
