Аннотация: Abstract. New experimental data on the interaction of igneous melts with hydrogen in a dynamic mode at a temperature of 1200 °C and hydrogen pressures (75 - 100 MPa) were obtained, which make it possible to understand the possible role of hydrogen in the processes occurring in magma in the earth's crust and the volcanic process under reducing conditions (f (O2) = 10-13 - 10-14). Natural samples of igneous rocks were used in the experiments: the magnesian basalt of the Northern breakthrough of the Tolbachik volcano (Kamchatka), and the andesite of the Avacha volcano (Kamchatka). On the basis of experiments, it has been shown that all the features of the interaction of hydrogen with basalt melts, established earlier in static experiments, are preserved, but at the same time the intensity of the release of the metallic phase and the degree of acidification of the original andesite and basalt melts are significantly increased.
