英文摘要	In the last 15 years, zeolite-like mayenite, Ca12Al14O33, has attracted significant attention in material science for its variety of potential applications and for its simple composition. Hydrogen plays a key role in processes of electride material synthesis from pristine mayenite: {Ca12Al14O32}(2+)(O-2) -> {Ca12Al14O32}(2+)(e(-))(2). A presence of molecular hydrogen in synthetic mayenite was not confirmed by the direct methods. Spectroscopy investigations of mayenite group mineral fluorkyuygenite, with empirical formula (Ca12.09Na0.03) (Sigma 12.12)(Al13.67Si0.12Fe0.073+Ti0.014+)(Sigma 12.87)O-31.96[F2.02Cl0.02(H2O)(3.22)(H2S)(0.15)square(0.59)](Sigma 6.00), show the presence of an unusual band at 4038 cm(-1), registered for the first time and related to molecular hydrogen, apart from usual bands responding to vibrations of mayenite framework. The band at 4038 cm(-1)corresponding to stretching vibrations of H-2 s at lower frequencies in comparison with positions of analogous bands of gaseous H-2(4156 cm(-1)) and H-2 adsorbed at active cation sites of zeolites (4050-4100 cm(-1)). This points out relatively strong linking of molecular hydrogen with the fluorkyuygenite framework. An appearance of H(2)in the fluorkyuyginite with ideal formula Ca12Al14O32[(H2O)(4)F-2], which formed after fluormayenite, Ca12Al14O32[square F-4(2)], is connected with its genesis. Fluorkyuygenite was detected in gehlenite fragments within brecciaed pyrometamorphic rock (Hatrurim Basin, Negev Desert, Israel), which contains reduced mineral assemblage of the Fe-P-C system (native iron, schreibersite, barringerite, murashkoite, and cohenite). The origin of phosphide-bearing associations is connected with the effect of highly reduced gases on earlier formed pyrometamorphic rocks.
