Summary of gas and sublimates analyses from Klyuchevskoy group volcanoes in 1939

This is a brief summary of gas analyses by I.Z. Ivanov of Kamchatka region volcanoes from 1939. Gas analyses were taken from four Klyuchevskoy volcano subsidiary craters: Tuyla, Biloikai, Tiranis and Kirgurich. Chemical composition of the gas analyses for 1939 for each volcano are presented as minimum and maximum values. Gas sublimates are reported simply as detects (DT).
