Abstract
Samples of the Dhajala meteorite (ordinary chondrite, type H3.8) were kept isothermically in a specially designed device in the temperature range from 300 to 800°C for 90 minutes. The composition and content of the released gases were studied on a gas chromatograph. The following were detected: CO, CO2, and H2O in concentrations of 10–60 µg/g of the sample; in addition, H2, CH4, and H2S in concentrations of 0.3–2 µg/g. The total nitrogen content during degassing increased quasi-linearly over time from 1–2 to 10–12 µg/g at each fixed temperature. Based on experimental observations of the change in the rate of nitrogen release depending on temperature, it was concluded that the effect of phase transitions depends on the permeability of the mineral matrix.
期刊介绍：
Doklady Physics is a journal that publishes new research in physics of great significance. Initially the journal was a forum of the Russian Academy of Science and published only best contributions from Russia in the form of short articles. Now the journal welcomes submissions from any country in the English or Russian language. Every manuscript must be recommended by Russian or foreign members of the Russian Academy of Sciences.
