The composition and content of fluid inclusions in the main structural and technological types of vein quartz of the Fenkina-Lampi deposit were studied by gas chromatography. It is shown that H2O dominates (90–99%) in the gases composition released from quartz under heating to 1000°C, CO2, CO, N2 and hydrocarbon compounds contents are much less. Quartz is characterized by high gassing in the high-temperature region (600–1000°C) comparable to gassing in the low-temperature interval (100–600°C), which is a negative indicator of the quality of quartz as a raw material for high-quality glass melting. It is necessary to develop a special purification technology for this quartz, which will take into account the features of its saturation with gas-liquid inclusions.
