Incorporation of hydrocarbons in the channels of cordierite crystallin
e structure was experimentally proved. It is necessary for the basing
of estimates of complex metamorphis fluid composition. It was found th
at cordierite selectively incorporates water and corbon dioxide molecu
les in relation to CH4, CO and othet components of C-O-H fluid. New ex
perimental technique of CO-H2O, CH4 - H2O fluid generation and after r
un gas phase composition measurement were developed.
